Just wanted to update on that I finally found a Sacred Hand of God, gave away my old T6 one to a new player. I also solo'ed the BRC. I could run the Trial of Blood, worked pretty well, only needed two tries. After that I did the Brains, was a breeze now that I have updated my gear.
It has lucky upgrade on both DMG and AR (150% AR) so my stats dmg wise are:
14-21k dmg
4620 AR
Still not the best, but good enough to trash Terror completely and trash Dest modestly
(Still have a hard time with Terror Baal though, no idea why).
Now, where can I find that sacred rare Hundgugel!
