so I lvled a Gem of Ease on PTR to lvl 25 to test it out. I then proceeded to get on a lvl 1 crusader at T6 adventure mode. I put the Gem in a Schaefer's Hammer. (it looked like one of the better choices of my available gear) Then I threw on a hellfire ring and a hellfire amulet. HOLY COW IS IT AWESOME!!! I proceeded to go out into the wild. In about 30 minutes I was lvl 38. The Hammer effect of lightning on being hit killed everything in 1 hit up to lvl 30. I just had to run around getting close to things and getting hit. I died at lvl 38 unfortunately to a stack of frozen orbs. I just wasn't being all that careful. I suspect around lvl 35 it is time to start dialing down the torment lvl due to champion affixes. They freaking hurt and can simply be unpredictable.
