[[File:Legem-interface-live1.jpg|thumb|300px|Legendary Gem interface window.]]
Legendary Gems will be added to Reaper of Souls in [[Patch 2.1]], and are currently undergoing testing on the [[PTR]]. The items add special bonuses when socketed in rings and amulets (only on Chars and not on Followers), and can be upgraded in power via [[Urshi]], the NPC who appears after [[Greater Rifts]] are cleared.  
+
Legendary Gems (or LGems or LeGems) were added to [[Reaper of Souls]] in [[Patch 2.1]], after extensive testing on the [[PTR]]. There were initially 14 types of Legendary Gems, with more added each [[Season]]. Most Legendary Gems have a function only when socketed in rings and amulets, this makes rings and amulets with sockets highly sought.  
  
While the developers are calling them "legendary gems" these socketables have nothing in common with regular [[gems]] in stats or appearance, and are more analogous to the {{iw|Unique_Jewels Rainbow Facet unique jewels}} of Diablo 2. The main difference in Diablo 3 is that these gems can only be socketed in jewelry, and the way the gems can be upgraded to improve their functions over time.
 
  
 +
==Rules of Drop and Use==
 +
Legendary Gems are only dropped from [[Greater Rift Guardians]], the final bosses of [[Greater Rifts.]] A Gem is guaranteed to drop if the player doesn't have on in his equipment, inventory or stash. This guarentees that a player will get all Legendary Gems without having to rely too much on the RNG. Duplicates are only possible if another character takes a Gem out of the stash.
  
==Legendary Gems Listing==
+
All gems are dropped at rank 0 and must be socketed into a ring or amulet, making such rings and amulets valuable. Players can use the [[Mystic]] to add sockets to ring and amulets they like. Socketing and removing work the same as with normal Gems.
  
While the Legendary Gems are still undergoing development on the PTR, their stats and bonuses are changing constantly. A major revision was created on July 15, 2014 with new or upgraded stats for almost every gem.  
+
Legendary Gems come with an effect with an upgradeable value in it. Each rank the gem gains increases the value by a set amount. Gems are upgraded by Urshi after completing a Greater Rift within 15 minutes. Players get 3 chances to upgrade gems for each rift. Upgrade odds are based on Gem Level and Greater Rift Level. When both are equal, the chance is 60%. When the Greater Rift is more than 6 level higher, the chances up, topping out at 100 % at 10 levels. If the Gem is higher, the chance is halved for each rank of difference. The max gem rank is 200, far beyond the highest Greater Rift Clear.

[[Enforcer]]
 
* Increase the Critical Hit Chance of your pets by 20%.
 
* Upgrade rank grants: +0.4% Critical Hit Chance. Max +20% upgrade (+40% total).
 
* Rank 50 unlocks: Your pets are unkillable.
 
Bliz Note: As was discussed in another thread, allowing this this gem to rank up to +100% pet Crit would likely cause undesired gearing issues and probably be a little out of line.
 
  
 +
Examples:
 +
* GRift level 17, LGem level 5 = +12 = 100% chance of successful upgrade.
 +
* GRift level 22, LGem level 14 = +8 = 80% chance of successful upgrade.
 +
* Grift level 22, LGem level 24 = -2 = 15% chance of successful upgrade.
  
[[Moratorium]]
+
Note that the odds recalculate with each successful upgrade, so a gem rolling successfully could be 100% on the first try, 90% on the second, and 80% on the third.
* 30% of all damage taken is instead staggered and dealt to you over 3 seconds.
 
* Upgrade rank grants: +0.1 second to the stagger duration.
 
* Rank 50 unlocks: 10% chance on kill to clear all staggered damage.

* Damage you deal is increased by 6% for every 10 yards between you and the enemy hit. Maximum 30% increase.

!Effect
* Upgrade rank grants: +0.1% for every 10 yards (+0.5% to max).
+
!Values
* Rank 50 unlocks: 30% chance on hit to Stun the enemy for 1 second.
+
!Rank 25 Bonus
Bliz Note: The max of 50 yards was added not because it was too powerful (even though it was too powerful), but so that you wouldn't be incentivized to stay offscreen while your pets killed everything. At 50 yards, I expect you to be in range to actually still use your skills (crazy right?).

==LGem Popularity==
  
[[Simplicity’s Strength]]
+
Legendary Gems were immediately embraced by players as a powerful new feature in the game, and sockets in jewelry became immediately sought after as mandatory [[end game]] affixes. Of all the gems, the offensive ones were the most popular and most used, since killing things faster is almost always the best and most fun strategy in Diablo III.
* Increase the damage of primary skills by 25%.
 
* Upgrade rank grants: +0.5% damage.
 
* Rank 50 unlocks: Primary skills heal you for 2% of maximum health on hit.
 
  
 +
As for defensive legendary gems, even in [[Hardcore]] they were hardly used, which prompted much bigger defensive bonuses on the gems in the second batch, [[Esoteric Alteration]] and [[Molten Wildebeest’s Gizzard]], added in [[Season Two]].
  
[[Bane of the Trapped]]
+
==Gem Upgrade Development==
* Increase damage against enemies under control-impairing effects by 20%.
 
* Upgrade rank grants: +0.5% damage.
 
* Rank 50 unlocks: Gain an aura that reduces the movement speed of enemies within 15 yards by 30%.
 
  
 +
The system was under construction all throughout the PTR and saw major changes during July and August, 2014.
  
[[Wreath of Lightning]]
+
Gems initially had 50 ranks, with the odds to upgrade[http://www.diablofans.com/forums/diablo-iii-general-forums/diablo-iii-general-discussion/90337-community-effort-legendary-gem-upgrading-effects] increasing on higher Greater Rift levels. This was reworked after a few weeks, and a patch on August 5, 2014 changed the maximum level from 50 to 200 and greatly increased the odds for multiple rank boosts per upgrade, as well as granting multiple upgrade opportunities on higher level greater rifts. <ref>[http://diablo.incgamers.com/blog/comments/diablo-3-ptr-2-1-0-patch-notes-5-august/comment-page-1?cpage=1#comment-8649488 Legendary Gem changes] - August 5th PTR Patch  5/08/2014</ref>
* 15% chance on hit to gain a Wreath of Lightning, dealing 500% weapon damage as Lightning every second to 1-2 nearby enemies for 3 seconds.
 
* Upgrade rank grants: +10% weapon damage per second.
 
* Rank 50 unlocks: While under the effect of the Wreath of Lightning, gain 25% increased movement speed.
 
  
 +
<blue>Legendary gems now start at rank 0
 +
* Changes have been made to the frequency at which Legendary gems are upgraded
 +
** Note: Because of this change the power of each upgrade has been reduced, but the overall rate at which gem power is gained through upgrades should remain roughly the same</blue>
  
[[Gem of Efficacious Toxin]]
+
That system was changed again late in the PTR, with the ranks cut from 200 to 25, and a whole new system of upgrade odds implemented, based on the difference in level between the gem and the Grift. Those odds were the final system which went live a few weeks later.
* Poison all enemies hit for 1000% weapon damage over 10 seconds.
 
* Upgrade rank grants: +20% weapon damage over 10 seconds.
 
* Rank 50 unlocks: All enemies you poison take 10% increased damage from all sources.
 
  
  
[[Pain Enhancer]]
+
==Legendary Gem Design Theory==
* Critical hits cause the enemy to bleed for 500% weapon damage as Physical over 3 seconds.
 
* Upgrade rank grants: +10% weapon damage over 3 seconds.
 
* Rank 50 unlocks: Gain Blood Frenzy, granting you 2% increased Attack Speed for each bleeding enemy within 20 yards.
 
 
 
 
 
[[Mirinae, Teardrop of the Starweaver]]
 
* 15% chance on hit to smite a nearby enemy for 1000% weapon damage as Holy.
 
* Upgrade rank grants: +20% weapon damage.
 
* Rank 50 unlocks: Smite a nearby enemy every 5 seconds.
 
 
 
 
 
[[Gogok of Swiftness]]
 
* 50% chance on hit to gain Swiftness, increasing your Attack Speed by 2% for 3 seconds. This effect stacks up to 10 times.
 
* Upgrade rank grants: +1% chance.
 
* Rank 50 unlocks: Gain 2% Cooldown Reduction per stack of Swiftness.
 
 
 
 
 
[[Invigorating Gemstone]]
 
* While under any control-impairing effects, reduce all damage taken by 30%.
 
* Upgrade rank grants: +1%. Maximum +50% upgrade (80% total).
 
* Rank 50 unlocks: Heal for 20% of maximum life when hit by control-impairing effect.
 
 
 
 
 
[[Boon of the Hoarder]]
 
* 30% chance on killing an enemy to cause an explosion of gold.
 
* Upgrade rank grants: +1% chance on kill.
 
* Rank 50 unlocks: Gain 30% increased movement speed for 3 seconds after picking up gold.
 
 
 
 
 
[[Taeguk]]
 
* Gain 1% increased damage for 4 seconds after spending primary resource. This effect stacks up to 10 times. Gaining a stack refreshes all existing stacks.
 
* Upgrade rank grants: +1 max stack.
 
* Rank 50 unlocks: Gain 1% increased Armor for every stack.
 
Bliz Note: This buff duration on this gem was chosen so that it’s easier to keep up with cheap spenders and not trivial with expensive spenders.
 
 
 
 
 
==Gem Upgrade Odds==
 
 
 
[[File:Legem-interface-large1.jpg|thumb|400px|Legendary Gem upgrade interface from a L19 GRift.]]
 
The only way to upgrade a Legendary Gem is via [[Urshi]], who only appears when a character defeats the Greater Rift Guardian '''''after''''' the 15 minute timer has expired. So players must fail to finish a Rift in time, but still continue on to clear it and kill the Guardian. (Who drops the same quality of loot in either case.)
 
 
 
The odds that a gem will be upgraded increase with each higher level Greater Rift completed in that game. There is also a chance that the gem will receive a double, triple, or quadruple upgrade, boosting it 1-4 levels in total. It's yet not known if anything effects the chances of a double or bigger upgrade, and most fans suspect it's pure [[RNG]].
 
 
 
The Legendary Gem upgrade chances are displayed in the [[tooltip]], so the following figures are not estimations, but are what the game actually says before each upgrade attempt.[http://www.diablofans.com/forums/diablo-iii-general-forums/diablo-iii-general-discussion/90337-community-effort-legendary-gem-upgrading-effects]

Legendary Gem interface window.

Legendary Gems (or LGems or LeGems) were added to Reaper of Souls in Patch 2.1, after extensive testing on the PTR. There were initially 14 types of Legendary Gems, with more added each Season. Most Legendary Gems have a function only when socketed in rings and amulets, this makes rings and amulets with sockets highly sought.


Rules of Drop and Use[edit | edit source]

Legendary Gems are only dropped from Greater Rift Guardians, the final bosses of Greater Rifts. A Gem is guaranteed to drop if the player doesn't have on in his equipment, inventory or stash. This guarentees that a player will get all Legendary Gems without having to rely too much on the RNG. Duplicates are only possible if another character takes a Gem out of the stash.

All gems are dropped at rank 0 and must be socketed into a ring or amulet, making such rings and amulets valuable. Players can use the Mystic to add sockets to ring and amulets they like. Socketing and removing work the same as with normal Gems.

Legendary Gems come with an effect with an upgradeable value in it. Each rank the gem gains increases the value by a set amount. Gems are upgraded by Urshi after completing a Greater Rift within 15 minutes. Players get 3 chances to upgrade gems for each rift. Upgrade odds are based on Gem Level and Greater Rift Level. When both are equal, the chance is 60%. When the Greater Rift is more than 6 level higher, the chances up, topping out at 100 % at 10 levels. If the Gem is higher, the chance is halved for each rank of difference. The max gem rank is 200, far beyond the highest Greater Rift Clear.

Upgrade Odds[edit | edit source]

GRift level vs. Gem Level +10 +9 +8 +7 +6 +5 +4 +3 +2 +1 0 -1 -2 -3 -4 -5 -6 -7
LGem Upgrade Chance 100% 90% 80% 70% 60% 60% 60% 60% 60% 60% 60% 30% 15% 8% 4% 2% 1% 0%


Examples:

  • GRift level 17, LGem level 5 = +12 = 100% chance of successful upgrade.
  • GRift level 22, LGem level 14 = +8 = 80% chance of successful upgrade.
  • Grift level 22, LGem level 24 = -2 = 15% chance of successful upgrade.

Note that the odds recalculate with each successful upgrade, so a gem rolling successfully could be 100% on the first try, 90% on the second, and 80% on the third.

Legendary Gems Catalog[edit | edit source]

Effect Values Rank 25 Bonus Notes
Bane of the Powerful
Bane-of-the-Powerful-icon4.jpg
Gain 20% increased damage for X seconds after killing an elite pack. Start:30 Increase:1 15% Increased Damage to Elites One of the most popular gems, this grants a big damage buff, works with every type of build, and enjoys around 100% up-time in Rifts, where Elites abound.
Bane of the Stricken
Bane-of-the-Stricken-icon4.jpg
Each attack you make against an enemy increases the damage it takes from your attacks by X% Start: 0.8% Increase: 0.01% Gain 25% increased damage against Rift Guardians and bosses This gem was added for Season 4
Bane of the Trapped
Bane-of-the-Trapped-icon4.jpg
Increase damage against enemies under control-impairing effects by X% Start: 15% Increase: 0.3% Gain an aura that reduces the movement speed of enemies within 15 yards by 30%. The Aura at Rank 25 has no visual display, but it does proc the gem itself; so monsters near the hero are slowed and thus take increased damage.
Boon of the Hoarder
Boon-of-the-Hoarder-icon4.jpg
X% chance to cause an explosion of gold when you kill an enemy Start: 25% Increase: 1.5% Gain 30% increased movement speed for 2 seconds after picking up gold. The first time found (on an account) it will only drop from Greed, found in The Vault.
Enforcer
Enforcer-icon4.jpg
Increases the damage of your pets by X% Start: 15% Increase: 0.3% Your pets take 25% reduced damage. The rank 25 bonus is irrelevant for pets that are not targeted and do not take damage, such as Hydras or Sentries.
Esoteric Alteration
Esoteric-Alteration-icon4.jpg
Gain X% non-Physical damage reduction Start: 10% Increase: 0.5% While below half Life, your resistances to Cold, Fire, Lightning, Poison, and Arcane are increased by 75%. A very powerful defensive gem, added in Season Two.
Gem of Ease
Gem-of-Ease-icon4.jpg
Monster kills grant +X experience Start: 500 Increase: 50 Level requirement reduced to 1 Sockets into Weapons rather than jewelry. Useful for twinking
Gem of Efficacious Toxin
Efficacious-Toxin-icon4.jpg
Poison all enemies hit for X% weapon damage over 10 seconds. Start: 1000% Increase: 50% All enemies you poison take 10% increased damage from all sources. A popular gem for big damage over time, but less useful for characters who kill enemies very quickly. One of the more powerul Rank 25 bonuses
Gogok of Swiftness
Gorgok-icon4.jpg
50% chance on hit to gain Swiftness, increasing your Attack Speed by X% for 4 seconds. This effect stacks up to 15 times. Start: 1% Increase: 1% Gain 1% Cooldown Reduction per stack of Swiftness The Attack Speed increase is useful to some builds, but this gem is most valued for the massive CDR granted by the Rank 25 property.
Iceblink
Iceblink-icon4.jpg
Your Cold skills now apply Chill effects and your Chill effects now slow enemy movement speed by an additional X% Start: 5% Increase: 0.4% 10% increased chance to critically strike Chilled or Frozen enemies One of two gems added in Season Three
Invigorating Gemstone
Invigorating-icon4.jpg
While under any control-impairing effects, reduce all damage taken by X% Start: 30% Increase: 0.4% Heal for 20% of maximum life when hit by a control-impairing effect. As with the other original batch of defensive gems, this is one of the least-used gems.
Mirinae, Teardrop of the Starweaver
Mirinae-icon4.jpg
15% chance on hit to smite a nearby enemy for X% weapon damage as Holy. Start: 1000% Increase: 40% Smite a nearby enemy every 5 seconds The smite can hit virtually any enemy on the screen, making the "nearby" description fairly inaccurate. On the whole this adds huge damage to individual targets, but not as much to large groups compared to other gems
Molten Wildebeest's Gizzard
Wildebeest-icon4.jpg
Regenerate X Life per Second Start: 10000 Increase: 1000 After not taking damage for 4 seconds, gain an absorb shield for 200% of your total Life per Second. Another powerful defensive gem added in Season Two. This gem synergizes well with defensive buffs that prevent the character from taking damage, and the Rank 25 power can fuel itself, as the shield keeps the player from taking damage.
Moratorium
Moratorium-icon4.jpg
35% of all damage taken is instead staggered and dealt to you over X seconds. Start: 3 Increase: 0.1 20% chance on kill to clear all staggered damage. Another of the initial batch of defensive gems that proved little-used.
Mutilation Guard
Mutilation-Guard-icon4.jpg
Gain X melee damage reduction. Start: 10% Increase: 1% Below 50% life, you may move through enemies unhindered A Defensive Gem added in Season 3
Pain Enhancer
Pain-Enhancer-icon4.jpg
Critical hits cause the enemy to bleed for X% weapon damage as Physical over 3 seconds. Start: 500% Increase: 30% 2% increased Attack Speed for each bleeding enemy within 20 yards. Best used with character with high Crit chance and AOE attacks.
Simplicity’s Strength
Simplicity-icon4.jpg
Increase the damage of primary skills by X% Start: 25% Increase: 0.5% Primary skills heal you for 2% of maximum health on hit. Probably the least used offensive gem from the initial batch, as primary skills are so weak compared to Spenders.
Taeguk
Taeguk-icon4.jpg
Gain 0.5% increased damage for 3 seconds after spending primary resource. This effect stacks up to X times Start: 20% Increase: 1 Gain 0.5% increased Armor for every stack. This gem adds huge damage when fully stacked, but the stacks take quite a while to build up, and any lull of just 3 seconds resets them to zero. The Rank 25 property is a powerful defensive bonus, especially for melee characters who can keep it stacked and active.
Wreath of Lightning
Wreath-icon4.jpg
15% chance on hit to gain a Wreath of Lightning, dealing X% weapon damage as Lightning every second to nearby enemies. Lasts for 3 seconds. Start: 600% Increase: 10% While under the effect of the Wreath of Lightning, gain 25% increased movement speed. A mini-Conduit Pylon, this gem zaps all nearby enemies for considerable damage. Radius is limited so close proximity to enemies is preferred.
Zei’s Stone of Vengeance
Zei-Stone-icon4.jpg
Damage you deal is increased by X% for every 10 yards between you and the enemy hit. Maximum 20% increase at 50 yards Start: 4% Increase: 0.05% 20% chance on hit to Stun the enemy for 1 second. The damage boost is calculated when damage is dealt, so movement changes the amount.

LGem Popularity[edit | edit source]

Legendary Gems were immediately embraced by players as a powerful new feature in the game, and sockets in jewelry became immediately sought after as mandatory end game affixes. Of all the gems, the offensive ones were the most popular and most used, since killing things faster is almost always the best and most fun strategy in Diablo III.

As for defensive legendary gems, even in Hardcore they were hardly used, which prompted much bigger defensive bonuses on the gems in the second batch, Esoteric Alteration and Molten Wildebeest’s Gizzard, added in Season Two.

Gem Upgrade Development[edit | edit source]

The system was under construction all throughout the PTR and saw major changes during July and August, 2014.

Gems initially had 50 ranks, with the odds to upgrade[1] increasing on higher Greater Rift levels. This was reworked after a few weeks, and a patch on August 5, 2014 changed the maximum level from 50 to 200 and greatly increased the odds for multiple rank boosts per upgrade, as well as granting multiple upgrade opportunities on higher level greater rifts. [1]

Legendary gems now start at rank 0
  • Changes have been made to the frequency at which Legendary gems are upgraded
    • Note: Because of this change the power of each upgrade has been reduced, but the overall rate at which gem power is gained through upgrades should remain roughly the same

That system was changed again late in the PTR, with the ranks cut from 200 to 25, and a whole new system of upgrade odds implemented, based on the difference in level between the gem and the Grift. Those odds were the final system which went live a few weeks later.


Legendary Gem Design Theory[edit | edit source]

Legendary Gem upgrade interface.

Blizzard's John Yang explained the design theory behind Legendary Gems while they were being tested on the PTR, July 15, 2014. [2]

Hi everyone. I wanted to pop in here while discussion on Legendary gems is ongoing.


First off, our philosophy on Legendary gems is that, when you pick one up for the first time, you should immediately want to use it, assuming it’s for your build, since some gems don’t apply to all builds/needs. This puts a minimum bar on the starting power level. After that, the power increase per upgrade is directly related to the frequency of upgrading, which is closely tied to the Greater Rift reward scheme and is still being iterated on. In the end, we’d like gems to be infinitely upgradeable when it makes sense, but not be outrageous.

Additionally, all Legendary gems have been disabled for followers. These powers were not designed for followers in mind, and this way we can ensure the gems are of a high power level because you can only have 3 equipped. In the future, if followers need avenues of advancement we would likely make Legendary gems specifically designed for them.

Now for the details. The existing stats you see on Legendary gems on the PTR today are somewhat placeholder. So, to steer further discussion in a direction that’s more in line with the next PTR build, here are the freshly tuned numbers (with some of my notes) for each gem.


Official Reveal[edit | edit source]

Legendary Gems were first revealed in June 2014 and the first official info came from Blizzard's Patch 2.1 preview blog. [3]

Legendary Gems are still undergoing significant iteration at this time, so you won’t see them available on the PTR right away. The gist is that these gems are infinitely upgradeable, and provide special Legendary powers when socketed into the appropriate gear slot. They can only be socketed into Rings and Amulets, and can be upgraded by completing additional Greater Rifts. The higher you place in a Greater Rift, the more likely your gem will be successfully upgraded. We’ll have more details in the future as we continue development on these powerful baubles, so stay tuned!
