Critical hits cause the enemy to bleed for 2,500% Physical damage over 3 seconds. You can level this Gem all the way up to rank 150. Every upgrade will increase the Physical damage by another 50% weapon damage up to a maximum of 10,000% total.
The rank 25 bonus is the true powerhouse of this Gem as it provides 3% increased additive Attack Speed for each bleeding enemy within a 20 yard radius. “Bleeding” in this case does not refer to the gem’s primary effect, enemies affected by any Physical Damage over Time effect (e.g. Chance to Bleed on Hit, Rend, Locust Swarm Cloud of Insects, Exploding Palm, Consecration Bed of Nails) will still give you the bonus Attack Speed.
Pain Enhancer Best Use
Widely used on Attack Speed dependent builds and group trash killers: This is a signature Gem for a lot of Pets builds as Pets scale pretty well with Increased Attack Speed. The Mundunugu Spirit Barrage Witch Doctor for instance is a build that gets tremendous value from this Gem.
Legendary Gem in Diablo 3
Legendary Gem Creation:
If you need extra Legendary Gems to level up, you can make the Rift Guardian in any Greater Rift drop a new Rank 0 Gem by removing all the Legendary Gems with the same name from your Equipment, Inventory and Stash.
The safest way to do that is to put them into the Inventory of different character.
