Changes

Legendary Gems (or LGems or LeGems) were added to [[Reaper of Souls]] in [[Patch 2.1]], after extensive testing on the [[PTR]]. There are were initially 14 types of Legendary Gems, all of which add with 3 more added in Season Two. Legendary Gems have a special bonus function only when socketed in rings and amulets, and they are very powerful items, so that a socket in all 3 jewelry items is considered mandatory for [[end game]] gear. (The value [[Gem of Ease]] is the bonus increases with each rank the gem is upgradedonly exception, with and it can only be socketed into a special special secondary power unlocked at level 25weapon. )

There is no upper limit to the gem's rankLGems drop only from Greater Rift Guardians, and some gems continue to improve considerably with every point. It's very difficult to raise a LGem's thus can only be obtained by level more than a few levels higher than 70 characters, (the one exception is the [[Boon of the maximum Grift a player Hoarder]]) though LGems have no level req and can clearbe used by any level character, so the practical limit a few weeks after Patch 2and they make very powerful [[twinks]].1 is around 50To upgrade LGems, players must interact with few players raising [[Urshi]], a gem higher than ghostly NPC who appears after the death of the low 40sGreater Rift Guardian.

The value of the bonus increases with each rank the gem is upgraded, with a special special secondary power unlocked at rank 25. These rank 25 powers vary widely in quality, from "makes the gem worth using" to "irrelevant for some builds." There is no theoretical upper limit to the gem's rank, and all gems improve with every rank. However, the odds are very poor to raise a LGem's level higher than the maximum Grift a player can clear, so for most players their LGems have a practical limit of several levels higher than their highest Greater Rift, and largest possible difference is 7 ranks. When 6 ranks higher than the Grift, there is a 1% chance the LGem will upgrade. * '''Diablo 2 Jewels''': While the developers call these items "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.

* Drop quite commonly (100% drop chance), but ** After a players will never find two has found one Boon of the same type of legendary Hoarder from Greed, that gem if they have is eligible to drop from Greater Rift Guardians.* At least one already on that Legendary Gem should drop from each GR Guardian, until a character or in their + stashhas all the gems. Duplicate gems are never dropped.** To find more than one of the same gem, you need to put the first gem on another characteror drop it in town before starting the Greater Rift.** This is actually a benefit to players seeking a specific gem, since holding the other types means you won't find any duplicates.* Can LGems can only be socketed into rings and amulets - not any other item types.* Only * [[Gem of Ease]] added in [[Season Two]] is the only exception; it sockets into weapons.* LGems only work when equipped on by players. Do They do not function when equipped on [[followers]].(Including Gem of Ease.)* Can LGems can only be upgraded with [[Urshi]], the NPC who appears only in [[Greater Rifts]]after the Guardian is defeated.

** If the level of the Grift is more than 10 higher than the rank of the gem, the odds are 100%for an upgrade. If the Grift is more than 7 levels lower than the gem, the odds are 0%. Full odds listed below.

After players kill Note that the Greater Rift Guardian they can use Urshi's interface to either odds recalculate with each successful upgrade , so a gem rolling successfully could be 100% on the first try, 90% on the GRK (which will go up at least 1 levelsecond, and possibly more 80% on the third. Urshi allows LGem upgrades any time she appears, even if they had a very fast run)player does not complete the GRift within 15 minutes. If completed within that time limit, players can choose 3 tries to upgrade gems, or choose to upgrade their Rift Key to a Legendary Gemhigher rank. (The Key Rank upgrade is always at least 1 level. One or If a player completes a GRift with more than 4:30 left, the other, but not both, so when players choose to Rift Key will upgrade an additional level for about every 45 seconds. Players who finish a LGem, they GRift very quickly can not upgrade a GRK and continue escalating that series of Greater Riftstheir Rift Key as much as 9 or 10 ranks.)

These stats changed several times during PTR testing. Here are the Legendary Gem stats as of [[Patch 2.1]], which went live in late August 2014. No changes were made to their stats (though many bugs were fixed) afterwards, up through Patch 2.1.2 in January 2015.* Three new LGems were added in [[Season Two]], beginning in February 2015. The [[Gem of Ease]], [[Molten Wildebeest’s Gizzard]], and [[Esoteric Alteration]].

Drops The first time found (on an account) it will only drop from [[Greed]], found in [[The Vault]]. The only This was tweaked in [[Patch 2.1.1]] and now this gem that doesn't can drop from GRift Greater Rift Guardians, providing it has previously been found from Greed on that account.

This is a very powerful [[twink]] item, and with the rank 25 power unlocked it lets a level one character equip any weapon in the game, instantly giving them incredibly-high damage. Testing on the PTR showed a character could hit level 40+ in less than 15 minutes playing solo.

Bliz Note: This buff duration on this gem was chosen so that it’s easier 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 up with cheap spenders it stacked and not trivial with expensive spendersactive.
