(Active and Passive Skills)

Line 1: Line 1:
'''Skills''' are what all abilities the character [[class]]es in [[Diablo III]] have are called. A skill includes regular physical abilities like [[Cleave]] or a magical [[spell]] like [[disintegrate]]. While '''skills''' is the official name, players often refer to them as '''spells''', '''talents''', '''abilities''', and similar terms. These are just synonyms, and are frequently interchangeable in use.
+
'''Skills''' refers to the Active Skills, the class-specific character abilities in Diablo III. There are around 25 skills per class, (down from 30+ in earlier versions<ref>[http://diablo.incgamers.com/blog/comments/jay-wilson-exclusive-full-transcript/ Jay Wilson Interview @ Diii.net] - IncGamers, October 2009</ref> of the game) and they are wildly-varied, ranging from physical strikes to [[spell]] attacks to buffs, debuffs, mind control abilities, and many more.
  
 +
Diablo III divides skills into [[Active]] and [[Passive]]. The skills selected to use are all Active, and these are attacks, debuffs, auras and other such abilities that only have an effect while they are being actively used. Passive skills (initially called [[traits]]) are limited to 3 per character, and they remain in effect indefinitely once they are enabled. (Though it may take special circumstances to trigger their effect, such as using a ranged attack.) There are dozens of passive skills per class, they vary widely between the classes, and add bonuses such as +damage to ranged attacks, faster movement speed, increased chance of critical strike, faster resource regeneration, improved healing, and many more.
  
Worth noting is that [[monster]]s can also use skills, but often not a Character skill. Primarily [[caster]] monsters have skills/spells, but others as well. Monster skills include all their abilities besides their "auto attack".
+
In Diablo III, skills are seldom used in their basic form, since the five types of [[runestones]] greatly modify every skill, always in beneficial fashion. There is thus no good reason to ever use the base skill once a runestone is available.  (Some players dislike this design, but the developers have said that at least one runestone in each skill will not modify the basic function, and will only add damage or some other improvement that doesn't change the basic function.)

This skill system has changed as often as any game feature during development, but seems at least semi-finalized as of January 2012. (See the archived skills page for details about the numerous earlier skill systems, many of which varied wildly from the final form.)
  
==Known Skills==
+
Characters now have six [[active skill slots]], which are unlocked at Clvl 1, 2, 6, 12, 18, and 24. Active skills become available to assign to these slots regularly, one every level or every other level, until the highest level skills are unlocked at around Clvl 29 (the number of skills and max level varies slightly from class to class). There are no skill points in Diablo III; skills are either selected or not; on or off.
  
[[Image:Skill-tree-blizzcon09-monk-muldric.jpg|thumb|right|200px|[[Monk skill|Monk Skill Tree]] interpretation by [http://forums.diii.net/showthread.php?t=739038 Muldric].]]
+
With the current system, a new character starts off wit one skill that they can not change or switch out, since only one skill is available at that level. Very quickly, as soon as the character reaches Clvl 2, another two skills are enabled, and a second active skill slot is unlocked. This gives the player a choice of three skills, two of which can be usable at a time. For example, a Wizard starts off with [[Magic Missile]], and no other skills available. At level 2, a second active skill slot comes online, and the skills [[Frost Nova]] and [[Ice Armor]] are enabled. Either of those can then be assigned to the second slot, or both can be used if one is swapped in for Magic Missiles.  
We know a fair number of skills from seeing them in demonstrations, and from taking notes of them at BlizzCon in October [[BlizzCon 2008|2008]] and [[BlizzCon 2009|2009]]. More than 30 skills each are known for the [[Barbarian]], [[Wizard]] and [[Witch Doctor]], while fewer of the [[Monk]]'s skills have yet been revealed. Click to the appropriate pages in the links above to learn the names and functions of all known skills.
 
  
==The Skill Design Team===
+
Additional active skill slots come in at level 6, 12, 18, and 24, with new skills available every level or two until about Clvl 29. At that point each class has about 24 active skills, of which six can be active at once.
  
[[Jay Wilson]] revealed the key skill designer guys on the Daiblo 3 team in an October 2009 interview. [http://diablo.incgamers.com/blog/comments/jay-wilson-exclusive-full-transcript]

===How Many Skills?===
+
==Passive Skills==
  
There will be around 35 skills per character in Diablo 3, as confirmed by [[Jay Wilson]] in an October 2009 interview: [http://diablo.incgamers.com/blog/comments/jay-wilson-exclusive-full-transcript/]
+
[[File:Skills-passive-beta1.jpg|thumb|300px|Passive skills for a Witch Doctor, Jan 2012.]]
 +
The [[Passive Skill]] system has undergone numerous changes as well, but it also seems mostly finalized as of January 2012, during the beta test.  
  
::'''''Diii.net: '''We saw 30-35 skills for the Wizard (30), Barbarian (35), and Witch Doctor (34), at Blizzcon. Can you give us an idea how close to the final skill trees those are?
+
In the current system, players can choose from 3 passive skills, with their [[passive skill slots]] becoming available at level 10, 20, and 30. Switching these in and out works much as it does with active skills, except that passive skills are first available at Clvl 10, when 2 of them are enabled. Additional passive skills come online every level or two thereafter, until each class has around 15 passive skills to choose by level 30.  
::'''Jay Wilson: '''In terms of the number of skills, that’s about right. In terms of the skill tree we’re um... we’re still playing around with the actual layouts of skill trees and the working of the skill system. The skills for the Wizard and Barbarian their skill trees were very solid.  We like their skills, though there are a few still missing. Especially for the Wizard, there are skills we didn’t put into her tree that we’re still defining, especially at the high end. The same for the Barbarian; we’ve got a few skills on the way for him. But for the most part, the content of those trees is more or less correct.

One major change from [[Diablo 2]] is that the various snaking lines of skill prerequisites are gone. In [[Diablo 3]] skills are enabled by spending skill points. In the [[BlizzCon 2009]] build, a character had to place 15 points in various skills before using Tier 4 skills. Which skills you put those points on that tier and below is up to you. This general tier-mechanic has stayed the same since [[BlizzCon 2008]], so will likely carry on to the final game.
 
  
  
==Skill Trees==
+
==Respecs==
The skill tree format we'll see in Diablo 3 has undergone many design changes, and is still in flux. The form seen at Blizzcon 2009 (represented by images on this page) was thought to be fairly final, but in November 2009 Blizzard let it be known that the UI had been entirely reworked, and was now quite different. No further details have since been revealed.
 
  
The first word came on November 21st. [http://diablo.incgamers.com/blog/comments/skill-trees-gone1 Skill trees gone], via two Twitter posts.
+
[[Respecs]] are readily-available in Diablo III, and players are encouraged to experiment with a wide variety of skills, as well as swapping them around between situations. This system has undergone much change during development, and remains in flux, with the final system of skills and runestones not yet finalized.
* The skill system revision is in full force. Trees begone! I think it might be a winner.
 
* We’re implementing and will be testing a new system that changes how skills are acquired. That’s all I’ll say.
 
  
[[Image:Skill-tree-blizzcon09-wiz-muldric.jpg|thumb|right|200px|[[Wizard skill|Wizard Skill Tree]] interpretation by [http://forums.diii.net/showthread.php?t=739038 Muldric].]]
+
While the developers initially shrugged off player complaints that total [[freespecs]] were an exploit that would prevent players from getting any sense of "ownership" or "identity" to their characters, the skills system during the beta has gradually changed to limit respecs, first by the [[Nephalem Altar]], then with a 30 second cooldown on using or changing any skill slot after it's been swapped.
Much player speculation ensued, some of it [http://diablo.incgamers.com/blog/comments/more-no-skill-trees-speculation/ was shot down], and a bit more explanation (without details) was offered on the 25th. [http://diablo.incgamers.com/blog/comments/non-skill-trees-discussion-evolves/]
 
:: Can you say why you guys decided to drop the skill tree? What deficiencies did it have that you felt another system could do better? --by JeffKamo
 
::: Focus. --by @Diablo
 
  
:: That is hard, so many games rely on skill trees. My guess would have to be… “skill” items that you find or even create for skills. -by CaptainCasey
 
::: Sounds like you’re talking about our skill rune system, which is still very much a part of the game. --by @Diablo
 
  
Jay Wilson provided some overview of the concept behind the changes in an interview in late November. [http://diablofans.com/forums/showthread.php?t=23550]
+
==Skill Points==
  
::'''Jay Wilson:''' This new system is still in the development stages and if it does not work, we still have plenty of options to fall back on. Right now, we're just trying different things and getting a feel for the few ideas in regards to the skill system that we have going on right now. It differs from the World of Warcraft/Diablo II type hierarchical styles and is more of a skill pool/path than a tree per se.
+
Skill points were removed from the game during development. The developers felt that skill points were a max skill cap by another definition, since most skills had to be maxed out to retain high utility. Skill points also proved difficult to balance, as additional points in some skills were of minimal importance, while they were essential in combat/damage skills.  
  
 +
Without skill points players can experiment by regularly swapping skills ([[respec]]) in and out, low level skills can scale up to remain useful long term, and equipment becomes much more important, as skill damage comes largely from equipment bonuses such as +attributes.
  
===Diablo 2 in Style===
 
  
One thing we do know about the skill trees in Diablo 3 is that they'll be fairly similar to those of Diablo 2, in terms of how quickly characters acquire new skills to play with. [http://diablo.incgamers.com/blog/comments/jay-wilson-exclusive-full-transcript/]
+
==Skill Requirements?==
  
::'''''Diii.net:''' Another follow up on that issue. People are wondering if the skills will be like Diablo 2 or more like World of Warcraft. Will we see more skills forever, or get the top level at level 30ish? 
+
[[File:Patch10-skill-swap-cooldown-sml.jpg|thumb|350px|[[Cooldown]] on skill switching, Beta v10.]]
::'''Jay Wilson: '''Diablo 2. We’re following the same model. Here essentially our Nightmare and Hell difficulties are an extension of normal difficulty, not a continuation of more content. So normal difficulty ends our core game, and then nightmare and hell are replays of them on higher skills levels. So we are going to allow you to continue and develop your skills into the higher difficulty levels.  
+
Diablo III has no skill requirements or prerequisites, other than minimum Clvls. Skills are no longer arranged in trees or grouped by tiers, and a new skill becomes available nearly every level up until Clvl 29 or 30. (The numbers vary between the classes.)
  
 +
This system, along with respecs and several other changes, is designed to let players freely experiment with skills and different builds.
  
===Skill Tree Changes During Development===
+
There are requirements on how many skills can be used at once. Characters start out with one skill, and unlock additional [[Active Skill Slot]]s at Clvl 2, 6, 12, 18, and 24.  [[Passive Skill Slot]]s  are enabled at Clvl 10, 20, and 30.
  
Only Blizzard knows exactly how many versions of the skill tree format they've gone through, but they've alluded to dozens of different major forms, and countless smaller varieties during their development period. At the skill panel during Blizzcon 2008 numerous different skill tree mock-up forms were shown on the powerpoint presentation.
 
* [http://diablo.incgamers.com/gallery/showgallery.php?si=&limit=&thumbsonly=0&perpage=18&cat=611&ppuser=&thumbcheck=0&page=1&sortby=&sorttime=&way=&cat=611 Skill trees] in the image gallery.
 
  
 +
==Resource Costs and Cooldowns==
  
====2008 Early Form====
+
Skills in Diablo III vary greatly in their resource costs. Some low level skills and [[signature skills]] have a low or even zero cost to cast, thus allowing players to [[spam]] them in all circumstances. More powerful skills have higher resource costs, to make using them more of a strategic choice. The highest level skills have very high resource costs, and/or cooldowns, forcing players to wait considerable times (up to 120 seconds for the highest level skills[http://diablo.incgamers.com/blog/comments/blizzard-on-high-level-barbarian-skill-cooldowns]) between uses.
  
[[File:Barb-juggernaut-tree08.jpg|thumb|2008 Format.]]
+
The point in resource costs and cooldowns is to give Diablo III's skills greater variety in effect and usage.[http://diablo.incgamers.com/blog/comments/blizzard-calms-the-masses-on-skill-cooldowns] In Diablo II there were very minimal cooldowns and resources costs became irrelevant to high level characters with lots of [[leech]], regeneration, or [[potions]]. As a result, every player could use their best skills constantly, without delay, and thus there was no reason to use lower level skills at all.  
The first skill tree shown to fans was revealed in the Blizzcon demo in late 2008. No official screenshots were released, though it was seen in [[:File:Barb-juggernaut-tree08.jpg|many photos and videos]] taken from the event. Only the Barbarian's can be judged, since the Witch Doctor only had 11 skills spread over his three trees. Of the Barbarian's 50+ skills, they were arranged much like Diablo 2's skills, with three distinct skill trees, displayed on tabs in the same interface window. Each row had 3-4 skills, and there were no prerequisite skills linked by columns. To move down a row in the tree, 5 points had to be spent on each row.
 
  
The skills were not as discrete as those in Diablo 2, and there was considerable overlap between skills in different trees. It appeared that the D3 team intended players to specialize in one tree per character, and thus included skills with redundant basic functions, such as +damage, +defense, etc.
+
Diablo III has been designed to encourage a wider mixture of skill types, with [[spammable]] skills mixed in with big damage/big delay skills, and others that fall inbetween. Lower level skills are meant to remain useful as their damage and effectiveness scales up with the character level.  
  
====2009 Evolution====
+
* See the [[cooldowns]] article for more detail, [[Blue]] quotes, and specific skill examples.
 +
<br>
  
A new style for skill trees was revealed in early 2009, when several screenshots were released along with BlizzCast 8. This was an evolutionary change, and there were still 3 tabs/trees per character, though each tree was more open and a fair number of column-style prerequisite lines had been added.
 
* [http://diablo.incgamers.com/gallery/showphoto.php?photo=2649&cat=611 Screenshot example].
 
  
 +
==How Many Skills At Once?==
  
This style changed entirely by Blizzcon 2009 in August, with the individual skill tree tabs removed. All characters now possessed one big skill tree with all 30+ skills arranged in rows. There were a few column-style prerequisites, but for the most part it was a large skill "menu," with only prerequisites of 5 points per column required to move down to the more powerful skills.  
+
Only 6 skills can be active at once, with the number available increasing as a character levels up. Characters start out with one skill and gain an additional [[active skill slot]]s at Clvl 2, 6, 12, 18, and 24.
  
No official images of this were released, but numerous exact recreations were mocked up by talented community artists.  
+
The maximum number of skills changed repeatedly during development. The first word that there would be any skill limit at all came in September, 2010. <ref>[http://diablo.incgamers.com/blog/comments/diablo-on-skills-party-help-and-beta-confirmation/ @Diablo] - IncGamers, September 2010</ref>
* [http://diablo.incgamers.com/gallery/showphoto.php?photo=3526&cat=611 Barbarian Skills].
+

It's known that the skill trees were largely reworked in late 2009, but no images or further details have yet been revealed.
+
This was at a time when skills were arranged in trees with tiers, which were arranged at Clvl 1, 2, 6, 10, 14, 20, and 26. Characters could activate multiple skills from any tier -- not just one from each tier -- and gained an additional skill point every level up.  
  
==Skill Caps==
+
The final game system bears almost no resemblance to that early design.
Bashiok spoke to this issue in a forum post in May 2009. [http://www.diii.net/blog/comments/diablo-iii-skill-trees-innovative-overhaul/]
 
  
::''Currently we’re envisioning the majority of skills to be capped at 5 points, to begin with. As a form of progression we're planning for players to be able to increase the point caps of skills. More than likely to a maximum of 15. It's a system that’s still under heavy design, but the fact of choosing and increasing key skills beyond their initial cap is important to this new unified tier system.''
 
  
Blizzard has not given any word on how these increased skill caps would be enabled, whether by Clvl requirements, quests/in-game achievements, item bonuses, or something else. Like the other features, it's under construction and will change between now and the game's release.
+
==Skill Tooltips==
  
There has been talk of [[rune]]s affecting the skill caps, or perhaps a secondary limited "skill point" system that lets you increase the cap of individual skills further.
+
[[File:Skill-tooltip-simplified-beta.jpg|thumb|350px|Simplified [[tool tips]].]]
 +
Skill tooltips were changed to be short and lacking in details (such as numbers) during late game development. Players reacted poorly to this change, but the developers insisted it was for the best and would be more [[accessible]] to new players.  Slightly more detailed skill information (showing damage types, some functions, numbers, etc) can be viewed by hovering on a skill while holding down the Control key.
  
 +
An side-by-side example can be seen to the right.
  
==Skill Display==
 
[[Image:Skill-threatening-shout.jpg|frame|Skill hover, May 2009.]]
 
The finer points of the skill hover have changed and evolved during the game's development, and will continue to do so. Expect further changes.
 
  
Hovering on a skill produces a visual like the one seen to the right. The name of the skill is displayed, along with the current and maximum points that a character may spend in it. The current function is shown, as is the increases you will enjoy with another point.
 
  
One prime difference from Diablo II is the slot for a [[skill rune]] that you see below the skill, in the skill tree. Only active skills (as far as is known) have slots for skill runes, and skill runes can be freely socketed and swapped in and out. (Subject to change during further development.) See the skill runes page for more details.
 
 
 
==Active and Passive Skills==
 
Diablo III skills are either "active" or "passive." There are many more passive skills than active skills. At Blizzcon in October 2008 (a very preliminary build of the game), each skill tree was set up in tiers, with 4 or 5 skills per tier. On each tier, one or two were active and the rest were passive.
 
 
Active skills are used by clicking their icon, and are generally direct attacks; things like [[Spirit_Skill_Tree#Soul_Harvest|Soul Harvest]], [[Battlemaster_Skill_Tree#Hammer_of_the_Ancients|Hammer of the Ancients]], or [[Arcane_Skill_Tree#Magic_Missile|Magic Missile]]. Active skills attack, cast a protective armor, stun monsters, etc.
 
 
Passive skills grant the character some sort of bonus that is always in effect. Passive skills do not need to be cast to activate them; they give a bonus all the time, as soon as points are placed into them. These are skills and spells like [[Arcane_Skill_Tree#Efficient_Magics|Efficient Magics]] or [[Battlemaster_Skill_Tree#Power_of_the_Battlemaster|Power of the Battlemaster]]. (No passive Witch Doctor skills have yet been named.) Passive skills boost the damage of other spells, lower the mana cost of casting them, increase their duration, etc. Passive skills were often called "masteries" in Diablo II, and that term is still applicable to many of them in Diablo III.
 
 
 
The balance of active and passive skills is an issue that must be tackled in character balancing. Jay Wilson spoke on this issue in an October 2009 interview. [http://diablo.incgamers.com/blog/comments/jay-wilson-exclusive-full-transcript/]
 
 
::'''''Diii.net: '''Based on playing those two characters and examining their trees, the Wizard has tons and tons of active attack skills and very few passives, while the Barbarian has an awful lot of defensive passives. Early on he didn’t have very many active skills. So fans were thinking we’d still see a lot of changes, and especially that the Wizard would be getting some more interesting passives.
 
::'''Jay Wilson: '''*sounding thoughtful* Um… yeah, the team has done more passes and passives on the Barbarian, so his are more developed. The Wizard is a little bit harder to do passives for. If you look at the Barbarian in D2, you see the same thing. A lot more passives and less actives than the wizard in D2. I think that’s more a difference between a melee char and a magic wielder.
 
 
::The fact that the Barbarian has a lot of passive defense is because he’s supposed to be tough. While I think that the Wizard probably doesn’t have enough passives, I would agree with that statement, keep in mind that they are two different classes.
 
 
==Abilities==
 
 
[[Abilities]] are actions all characters can perform, such as [[throw]], [[attack]], [[unsummon]], and [[resurrect]]. Just how many of these we'll see in Diablo 3 is not yet known, and this coverage is somewhat speculative, but we're assuming that at least the ones from Diablo 2 will return.
 
 
==Skills Define Characters==
 
D3 Lead Designer [[Jay Wilson]] discussed how skills drive game development, and vice versa, in a December 2008 interview with 1up.com[http://www.1up.com/do/previewPage?pager.offset=1&cId=3172030&p=1]. The D3 team later coined the expression "[[signature skill]]s" to express this further. Skills that truly guides the rest of the development of a class.
 
 
::'''1UP: In creating this game, would you say that the character classes and their powers drive the rest of the game, or are their powers created as a result -- or solution -- to problems presented by the game?'''
 
 
::'''JW:''' Probably the best way to describe it is that initially, when we're doing skills for a class, we're not thinking anything except "what makes this class awesome? Why do I care about this guy?" Then you say, "Because he can hit the ground and create a small localized earthquake that destroys everything in front of him." That sounds pretty awesome; that sounds like a guy that I'd want to play. So early on, that's really our fixation: What is going to make this class sing? But that only really drives the first half-dozen skills. After that, we start getting into what mechanics have we put in the game that we want this class to take advantage of. For example, with the Wizard, we gave her a passive skill that causes enemies to drop mana orbs -- just like health orbs. So that's a mana-recovery mechanic for her; it plays into her resource and plays into the health-orb system.
 
 
::So there, we just said, "We need a recovery mechanism for her -- what would work? Well, we can give her something similar that we already give for health." But then that doesn't mean anything for the Barbarian since he uses a completely different resource. For him, we tend to focus on skills that make him play in a way that's interesting. His "fury resource" is designed to drive the player forward, like a Barbarian, because he's very tough and is a close-quarters combatant. He wants to move forward, because the mechanic is "I have a lot of fury, which helps me deliver a lot of damage, but I'm going to lose it just sitting around." It makes him very aggressive, which is what we wanted out of the character. So that was driven by [the concept of] how do we want this guy to play. Very aggressively, and hence we built this mechanic.
 
 
::And lastly, [there's] the monster design. As we get further and further into the game, our goal is to make monsters that we can't figure out how the player can defeat [with the existing skills] and give the player the tools they need to defeat them. So the design of the monsters has a direct relationship to the design of the classes. That's kind of an ongoing thing; we [decide] "Let's create a monster that has really debilitating rooting attacks that just get you stuck when you encounter them." Then we see that this really screws with the Barbarian, so we give him a skill that lets him break out of roots so that he can counter that. Those things are interesting and allow for the player to have a broader, deeper character. On the other hand, we don't want to go too far -- a lot of mechanics of World of WarCraft are based heavily on control, and we want to make sure that Diablo 3 stays mostly a combat game based mostly on attacks.
 
 
 
Also on this topic, Jay Wilson spoke about how much planning the team puts into potential character builds. October 2009 interview: [http://diablo.incgamers.com/blog/comments/jay-wilson-exclusive-full-transcript/]
 
 
::'''''Diii.net: '''Do you guys work and plan in advance to plan multiple potential builds for each character? Or do you just throw in as many cool skills as you can and see how players find ways to use them?
 
::'''Jay Wilson: '''A little bit of both. We try to anticipate what we think will be good builds. For example, there’s lots of things we put into the wizard, to try to make a battle mage more viable. But sometimes we put in skills that we’re not 100% sure is an awesome skill, but that we think somebody will find an awesome use for. We try to plan things ahead of time, but we’re not foolish enough to believe that the three of us who work on skills can come up with as many possibilities and variations as the millions of players who will take the work we’ve done and have fun building stuff with it. We mostly try to make sure they have the tools to have a lot of freedom and create a lot of cool stuff.
 
 
==School of Skills==
 
Skills currently lack a lot of information of what type of skill they are. When the game is released, we will be able to decipher a lot more of these. For now, terms such as "schools" of skills (or spells) are generally speculation to make it easier to understand the mechanics behind them.
 
 
All abilities, spells etc are classed as "Skills" at the moment, but this could also change. DiabloWiki is simplifying this by talking about three types of skills:
 
* Magical Skills
 
* Supernatural Skills
 
* Extraordinary Skills
 
Magical skills are all types of skills that use [[mana]] or is of a magical nature, like a monster being able to summon allies, despite not having mana, or being a traditional [[caster]].
 
 
Supernatural skills are the type of feats a [[Barbarian]] typically would do. They are not magical as such, but they don't ''really'' follow traditional physical laws.
 
 
Extraordinary skills are just that: Extraordinary. Very strong monster/character, someone who can jump very high, use a chemical compound to "breathe fire", etc.
 
 
 
==Development==
 
[[Image:Barb-berserker-tree.jpg|thumb|150px|Berserker Skill Tree. Oct 2008.]]
 
The first sighting of skill trees was in the [[BlizzCon 2008]] build where more than 50 skills were shown for the [[Wizard]] and [[Barbarian]] and placed in three individual trees, similar to how the system worked in [[Diablo II]] and [[World of WarCraft]]. Each 5 points spent in a tree opened a new tier to put skill points in. That game design favoured specializing in one tree, and did not have any prerequisites, instead totally based on points spent in each tree.
 
 
At that point there were just 4 tiers of skills. Tier 1 was available at level 1, Tier 2 at level 5, then at 10 and 15. There was a fifth tier at level 20, but no skills were displayed in it. The image to the right is from that era.
 
 
The [[D3 Team]] mentioned that they were experimenting with allowing certain skills to have higher skill caps, but did not give details such as if it would be [[Clvl]] based, item based, points spent or something completely different.
 
 
[[Image:Skill-tree-berserker.jpg|thumb|left|150px|[[Berserker Skill Tree]]. April 2009.]]
 
This layout had changed a great deal by March 2009, when the next skill tree image was released. You see it to the left. The basic form remains, but the skills are staggered out over more tiers. Also note that the tiers are not labelled; they may no longer proceed at 5 point intervals. It's also possible that tiers will grow longer, with higher level skills being added as development proceeds.
 
 
[[Image:Wizard_skill_tree.jpg|thumb|right|150px|Barely discernible [[Wizard]] Skill tree at PAX 2009.]]
 
[[Bashiok]] elaborated on this in a forum post in May 2009 [http://www.diii.net/blog/comments/diablo-iii-skill-trees-innovative-overhaul/] saying the trees had been unified to one single page that "allows you to spend wherever you like." This overhaul of the skill system merging the skill trees but the group of skills kept their skill tree names.
 
 
The skill requirement still opened up in tiers, but opened up to all trees at the same time, enabling a player to pick low level skills in one tree, continuing with medium level skills in another and high level skills in the third.
 
 
The general theory of skill trees is to encourage character specialization, but not force [[cookie cutter]] style character builds. The removal of individual skill trees means that every character can now pick from all the possible skills; this is great in theory, since players can all use whatever skills they want, Tier conflicts permitting. On the other hand, if the skills aren't very well balanced, every character will end up using the same few skills, since those are the best, and the cookie cutter-ism on [[Battle.net]] could be insane.
 
 
[[Image:Skill-tree-blizzcon09-barb-muldric.jpg|thumb|right|150px|Fan-made representation of how it looked at [[BlizzCon 2009]]. Made by [http://forums.diii.net/showthread.php?t=739038 Muldric].]]
 
Bashiok defended the design saying it "diversifies the types and amounts of builds available to players," and explaining another advantage is that the [[D3 Team]] "don't have to throw in skills that are important, such as damage mitigation, all over the place."
 
 
"Every barbarian is probably going to want [[whirlwind]]. And why not? What this tree style allows for, and one reason we’re pretty keen on it, is that we aren’t saying “You’re a ‘berserker’ barbarian, you can’t have whirlwind”. Instead, you’re a [[barbarian]]!, pick the key skills that define you and your character as you want them to be."
 
 
Exactly how the D3 Team pulls this off without making every character use the same "best" skills is something worth monitoring as the game continues its development.
 
 
The overhaul did also see the removal of many relatively redundant skills, primarily removing [[passive skill]]s.
 
 
 
The whole skill system is being reworked, and [http://diablo.incgamers.com/blog/comments/skill-trees-gone1/ Blizzard has said] that the skill tree system is being removed completely. [[Bashiok]] mentioned Blizzard is "implementing and will be testing a new system that changes how skills are acquired." (Nov 20, Blizzard’s @Diablo channel at Twitter). Also, on an interview between Diablofans.com and [[Jay Wilson]], the latter explained a bit about how the new skill system might be. Removing the tree-type architecture and moving into a purely skill-based system. How the skill system will exactly work remains unknown for the time being.
 
 
::'''Jay Wilson:''' ...We've decided to remove the tree-type architecture and we are moving into a purely skill-based system. This new system is still in the development stages and if it does not work, we still have plenty of options to fall back on. Right now, we're just trying different things and getting a feel for the few ideas in regards to the skill system that we have going on right now. It differs from the World of Warcraft/Diablo II type hierarchical styles and is more of a skill pool/path than a tree per se.'''

Latest revision as of 23:24, 29 January 2012

Skills refers to the Active Skills, the class-specific character abilities in Diablo III. There are around 25 skills per class, (down from 30+ in earlier versions[1] of the game) and they are wildly-varied, ranging from physical strikes to spell attacks to buffs, debuffs, mind control abilities, and many more.

Diablo III divides skills into Active and Passive. The skills selected to use are all Active, and these are attacks, debuffs, auras and other such abilities that only have an effect while they are being actively used. Passive skills (initially called traits) are limited to 3 per character, and they remain in effect indefinitely once they are enabled. (Though it may take special circumstances to trigger their effect, such as using a ranged attack.) There are dozens of passive skills per class, they vary widely between the classes, and add bonuses such as +damage to ranged attacks, faster movement speed, increased chance of critical strike, faster resource regeneration, improved healing, and many more.

In Diablo III, skills are seldom used in their basic form, since the five types of runestones greatly modify every skill, always in beneficial fashion. There is thus no good reason to ever use the base skill once a runestone is available. (Some players dislike this design, but the developers have said that at least one runestone in each skill will not modify the basic function, and will only add damage or some other improvement that doesn't change the basic function.)

Essential Skill Links[edit | edit source]


Active Skills[edit | edit source]

This skill system has changed as often as any game feature during development, but seems at least semi-finalized as of January 2012. (See the archived skills page for details about the numerous earlier skill systems, many of which varied wildly from the final form.)

Characters now have six active skill slots, which are unlocked at Clvl 1, 2, 6, 12, 18, and 24. Active skills become available to assign to these slots regularly, one every level or every other level, until the highest level skills are unlocked at around Clvl 29 (the number of skills and max level varies slightly from class to class). There are no skill points in Diablo III; skills are either selected or not; on or off.

With the current system, a new character starts off wit one skill that they can not change or switch out, since only one skill is available at that level. Very quickly, as soon as the character reaches Clvl 2, another two skills are enabled, and a second active skill slot is unlocked. This gives the player a choice of three skills, two of which can be usable at a time. For example, a Wizard starts off with Magic Missile, and no other skills available. At level 2, a second active skill slot comes online, and the skills Frost Nova and Ice Armor are enabled. Either of those can then be assigned to the second slot, or both can be used if one is swapped in for Magic Missiles.

Additional active skill slots come in at level 6, 12, 18, and 24, with new skills available every level or two until about Clvl 29. At that point each class has about 24 active skills, of which six can be active at once.

View the images below to see a character at level 1, level 2 with the second active skill slot unlocked, and level 13, with 4 active skills slots, to see this progression.

  • The icons of skills that are available but not currently active are bright and colorful.
  • The icons of skills that are not yet available (due to a character not being high enough level) are dimmed out.
  • The icons of skills that are currently selected have a small silver border around them, for ease of identification.


Passive Skills[edit | edit source]

Passive skills for a Witch Doctor, Jan 2012.

The Passive Skill system has undergone numerous changes as well, but it also seems mostly finalized as of January 2012, during the beta test.

In the current system, players can choose from 3 passive skills, with their passive skill slots becoming available at level 10, 20, and 30. Switching these in and out works much as it does with active skills, except that passive skills are first available at Clvl 10, when 2 of them are enabled. Additional passive skills come online every level or two thereafter, until each class has around 15 passive skills to choose by level 30.

You can see full lists of all passive skills on the appropriate class skill pages.


Respecs[edit | edit source]

Respecs are readily-available in Diablo III, and players are encouraged to experiment with a wide variety of skills, as well as swapping them around between situations. This system has undergone much change during development, and remains in flux, with the final system of skills and runestones not yet finalized.

While the developers initially shrugged off player complaints that total freespecs were an exploit that would prevent players from getting any sense of "ownership" or "identity" to their characters, the skills system during the beta has gradually changed to limit respecs, first by the Nephalem Altar, then with a 30 second cooldown on using or changing any skill slot after it's been swapped.


Skill Points[edit | edit source]

Skill points were removed from the game during development. The developers felt that skill points were a max skill cap by another definition, since most skills had to be maxed out to retain high utility. Skill points also proved difficult to balance, as additional points in some skills were of minimal importance, while they were essential in combat/damage skills.

Without skill points players can experiment by regularly swapping skills (respec) in and out, low level skills can scale up to remain useful long term, and equipment becomes much more important, as skill damage comes largely from equipment bonuses such as +attributes.


Skill Requirements?[edit | edit source]

Cooldown on skill switching, Beta v10.

Diablo III has no skill requirements or prerequisites, other than minimum Clvls. Skills are no longer arranged in trees or grouped by tiers, and a new skill becomes available nearly every level up until Clvl 29 or 30. (The numbers vary between the classes.)

This system, along with respecs and several other changes, is designed to let players freely experiment with skills and different builds.

There are requirements on how many skills can be used at once. Characters start out with one skill, and unlock additional Active Skill Slots at Clvl 2, 6, 12, 18, and 24. Passive Skill Slots are enabled at Clvl 10, 20, and 30.


Resource Costs and Cooldowns[edit | edit source]

Skills in Diablo III vary greatly in their resource costs. Some low level skills and signature skills have a low or even zero cost to cast, thus allowing players to spam them in all circumstances. More powerful skills have higher resource costs, to make using them more of a strategic choice. The highest level skills have very high resource costs, and/or cooldowns, forcing players to wait considerable times (up to 120 seconds for the highest level skills[1]) between uses.

The point in resource costs and cooldowns is to give Diablo III's skills greater variety in effect and usage.[2] In Diablo II there were very minimal cooldowns and resources costs became irrelevant to high level characters with lots of leech, regeneration, or potions. As a result, every player could use their best skills constantly, without delay, and thus there was no reason to use lower level skills at all.

Diablo III has been designed to encourage a wider mixture of skill types, with spammable skills mixed in with big damage/big delay skills, and others that fall inbetween. Lower level skills are meant to remain useful as their damage and effectiveness scales up with the character level.

  • See the cooldowns article for more detail, Blue quotes, and specific skill examples.



How Many Skills At Once?[edit | edit source]

Only 6 skills can be active at once, with the number available increasing as a character levels up. Characters start out with one skill and gain an additional active skill slots at Clvl 2, 6, 12, 18, and 24.

The maximum number of skills changed repeatedly during development. The first word that there would be any skill limit at all came in September, 2010. [2]

You can spend into seven skills at a time, total. These are active skills and don’t include passives. --Diablo

This was at a time when skills were arranged in trees with tiers, which were arranged at Clvl 1, 2, 6, 10, 14, 20, and 26. Characters could activate multiple skills from any tier -- not just one from each tier -- and gained an additional skill point every level up.

The final game system bears almost no resemblance to that early design.


Skill Tooltips[edit | edit source]

Simplified tool tips.

Skill tooltips were changed to be short and lacking in details (such as numbers) during late game development. Players reacted poorly to this change, but the developers insisted it was for the best and would be more accessible to new players. Slightly more detailed skill information (showing damage types, some functions, numbers, etc) can be viewed by hovering on a skill while holding down the Control key.

An side-by-side example can be seen to the right.
