===Difficulty Level Progression==

It's not known how non-random [[Superunique]] bosses will gain properties. In Diablo 2 SuperUnique bosses (but not Act Bosses) got one or two preset mods, have static modifiers and added one random to that on Nightmarespawn locations, and two on Hellgenerally do not come with minions (outside of some [[quest]] bosses).

Most of the special, random modifiers found on bosses in Diablo 3 are reminiscent of {{iw|Monster_modifier#Unique_Monster_Bonuses those seen in Diablo 2}}, but there are many new ones mixed in. All of the bosses seen (on normal difficulty) in the Blizzcon 2008 and 2009 demos had at least one modifier, but quite a few had two. That seems to not be a feature in the final game, where random Normal bosses only get  . It's not known if the bosses with two mods were [[SuperUniques]] sporting their own innate mod + a random one, or if some bosses can just spawn with multiple modifiers on normal difficulty. Plenty of [[champions]] spawned with one or two properties as well, something never seen in Diablo II. This page is the master listof boss modifiers. Each entry has a brief listing here; click to the individual pages for a fully detailed listing with screenshots and gameplay reports.

  ===Ballista=== [[Ballista]] was a new property seen in the Blizzcon 2010 demo. This modifier appeared to increase the size and damage of their projectiles, but the damage wasn't noticeably giant, and the shots didn't explode upon impact, as Warcraft 2 fans might have expected, given the utility of the human catapult, the Ballista, in that title. * Monster Level Minimum: ?* Available to: All* Damage Type: N/A* Additional Resistances: None  ===Cold Aura=== [[Cold Aura]] reported by a fan from the Blizzcon 2009 demo. It has not been seen since, and is considered unconfirmed. It reputedly worked just as it did in Diablo 2, chilling and slowing players within the radius of effect. Interestingly, it was not until after that year's Blizzcon that [[Jay Wilson]] let it be known that [[Auras]] would return to the game, most likely as [[Monk skills]].* Monster Level Minimum: ?* Available to: Bosses only.* Damage Type: Cold* Additional Resistances: Cold<br>

[[Fast]] does what you'd expect, just more quicklyis precisely as it sounds. These monsters have a 40% bonus to their movement speed, and can thus prove quite difficulty to avoid, or to track down if they run.

[[Fire Chains]] appear and disappear rapidly, linking Champions with flaming chains that deal fire damage to nearby players and their minions. This property only appears past Normal difficulty, and only on Champions. (Not on bosses.)A monster with fire chains will attempt, as a group, to surround or box in a player to inflict maximum damage.

* Monster Level Minimum[[Illusionist]] Bosses and Champions are able to create duplicates of themselves, much as {{iw|Baal Baal}} did in Diablo II: ?* Available Lord of Destruction. The clones have the same properties as the original, potentially including the ability to: ?* Damage Type: ?* Additional Resistances: ?resurrect or summon new monsters. The illusions have very low health points, so they die fairly quickly, but they do not drop any items. Certain properties can be bestowed to the illusion, such as [[Fast]]. The illusions are capable of inflicting damage as well.

===Mirrored=== Mirrored Bosses and Champions are able to create duplicates of themselves, much as {{iw|Baal Baal}} did in Diablo II: Lord of Destruction. The clones have the same properties as the original, potentially including the ability to resurrect or summon new monsters. The Mirrored versions have only half the hit points of the original, so they die fairly quickly, but they do not drop any items. Individual bosses are able to produce numerous clones at the same time, potentially making their own minion packs. Actual minions can not create Mirrors, though a Champion pack with Mirrored can turn into quite an ordeal. [[Mirrored]] was originally called [[Doppleganger]], and was later named [[Illusionist]].

===GrenadierMortar===

[[Mortar]] bosses were briefly seen during is a property where the betaelite will fire off firebombs over the head of the player, theoretically hitting the edge of the screen, although this is often not the case. The name was changed design intention is to keep players in melee range, or to punish ranged players with a specific attribute as melee players are often besieged by [[Plagued]] or [[GrenadierMolten]], while the function remained much tattributes.

* Damage Type: ?Fire.

===LinkedHealth Link===Health [[linkedHealth Link]] bosses and champions were first seen in the Blizzcon 2010 demo, and feared. This mod "links" the hit points of all the champions, or the boss and his minions, essentially giving them all one huge health pool. This makes it impossible to kill any single target quickly, since all of the enemies lose hit points at the same rate, until the health link breaks when they are very low on hit points.

It's dangerous since you a single monster can't pick them be picked off one at a time, and you can't kill one cannot be killed quickly to lessen the damage they're dealingbeing dealt. All of the monsters stay on the attack until they're nearly dead, at which point they de-link and usually drop over one right after the other. That aspect of it is a fun mod, since the whole group goes over like dominoes once one of them succumbs.

[[Plagued]] bosses add poison damage to their attacks, and presumably enjoyed greater resistance to poison damage as well. They gave give off a visual identifier, with little clouds a distinct pool of green smoke rising up from them. Upon death they explode in a huge cloud of poisonous gaspoison underneath their feet.The pool inflicts [[http://twitterAoE]] damage to any player or minion standing within the substance.com/Diablo/status/37649605197832192]

===PowerfulShielding===

[[PowerfulShielding]] was seen in is a modifier that allows the Blizzcon 2010 demoelite to become temporary invulnerable to all sources of damage, but not understood completelyincluding damage-over-time abilities ([[DoT]]s) that were cast/inflicted before the shield went up. It sounds like the Diablo III version of "Extra StrongMonsters who are shielded," a Diablo II mod that granted bonus damage similar to [[Invulnerable]] monsters, but that wasn't clear from the play testingcan still be snared, rooted, or feared. Nor did these bosses seem The shields have a fairly long duration (up to have any specially greater amount ten seconds), and an elite will shield of hit pointsits own volition, meaning that an individual monster in a pack will shield at different times from its brethren.

* Available to: ?Rare/Champion* Damage Type: Nn/A.a* Additional Resistances: None.  ===Stoneskin=== [[Stoneskin]] returns from Diablo II, once again granting monsters much higher defense. It doesn't seem to improve the monster's hit points or resistances though, as [[Wizard]]s found monsters with this one easy prey. * Monster Level Minimum: ?* Available to: All.* Damage Type: Standard.* Additional Resistances: Physical.n/a

===VampirificVampiric===

[[VampirificVampiric]] is life leech in Diablo III, and player reports from Blizzcon 2009 ranked this among the worst of the boss modifiers. The life leech was very high from this one, and some players found these guys literally impossible to kill, since they'd heal almost fully with a single hit, while it took dozens of hits to kill them.[http://diablo.incgamers.com/blog/comments/bosses-and-champions-in-diablo-3/]

It's likely This section lists modifiers that others on this page are known to have been removedfrom the game. ===Ballista=== [[Ballista]] was a new property seen in the Blizzcon 2010 demo.

Doppleganger was the original name of the modifier now called [[MirroredIllusionist]]. See that entry for full details. ===Magical=== [[Magical]]. This modifier was seen several times during Blizzcon 2009 play testing, but its effect wasn't apparent to any of the players. * Monster Level Minimum: ?* Available to: ?* Damage Type: ?* Additional Resistances: ? <br>  ===Multishot=== [[Multishot]] returns from Diablo II. [http://blues.incgamers.com/Posts/1/1/4/10/6548/diablo-iii-health-globes#postId_17794]. It's nastier by itself in Diablo III, since ranged attackers pack more of a punch than most of them did in Diablo II, and a boss or champion pack of ranged attackers with this mod can emit some serious ordinance.

* Monster Level Minimum: ?* Available to: All.* Damage Type: N/A.* Additional Resistances: None. <br> ===MortarMythical=== [[Mythical]] was seen several times during Blizzcon 2009 play testing, but its effect wasn't apparent to any of the players. * Monster Level Minimum: ?* Available to: ?* Damage Type: ?* Additional Resistances: ? <br> ===Powerful=== [[Powerful]] was seen in the Blizzcon 2010 demo, but not understood completely.
