Bane of Stricken is a Legendary Gem in Diablo III, originally scheduled to be added in patch 2.2.0, but later moved to 2.3.0 instead. It can only be socketed into Amulets and Rings, and drops from Greater Rift Guardians. It was cut from the 2.2 release, replaced with Mutilation Guard. This gem was only available to players participating in Season Four, but drops for normal characters as well since that Season's end.
