Bane Of The Trapped Vs Bane Of The Powerful

Bane of the trapped is a legendary gem findable only from greater rift guardians in reaper of souls. Legendary gems can only be socketed in rings and amulets worn by a character (not by a follower) and provide dramatic and powerful bonuses that are huge upgrades over any normal gems in the game. All legendary gems improve with upgrades to rank 50,. Nothing else gives you a flat 30% multiplicative damage boost like trapped does.
