This Legendary Gem increases Life Regeneration by 10,000 per Second. You can level this Gem all the way up to rank 150. Every upgrade increases the Life Regeneration by 1,000 per Second up to a total of 160,000 per second.
On top of that the secondary rank 25 grants you a shield for 200% of your total sheet Life per Second after not taking any damage (including damage absorbed by shields) for 4 seconds. Life per Second effect from skills, passives and other items also count towards this shield effect.
Molten Wildebeest’s Gizzard Best Use
Very useful synergy with Squirt’s Necklace: Can be used for Speed runs to protect Squirt’s Necklace’s buff. Has a nice synergy with Draw Life, Mantra of Healing and other Life per Second increasing buffs. Sometimes used on supports for sustain.
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.
