Had only soloed to end of Act I but she was geared OK enough so we jumped into Act III with a couple of friends (WD and Monk) on a normal run. Stonefort - not too much of a problem, KW dealt with, Keep Depths 1 & 3 OK.
Craters were going OK, dealt with the 1st phasebeast pack OK.
Dealt to an elite pack and there was a Goblin just past it. I leapt to the other side of the Gob to herd it back towards my team, right into a blue pack of Molten/firechain/.?./.?. soul rippers that I didn't see.
Lasted a little bit with Ignore Pain but was too far away for the other two to be of any help.
I don't think she managed to take any of the rippers out herself but she was avenged by the monk and WD.
RIP Thundress, at least you went down swinging.
