Eh, it’s kill or be killed. Bring some small healing potions and blast away. There are a lot of good def down heroes to help you get through the mob waves faster (i.e. taking less damage). Rogues also have a chance to dodge specials, if they have emblems. You just gotta approach it a different way.
I actually have more trouble with the trials where I have no or only a few hitters. I’ll be rolling into the Trials of Fortitude (druids and clerics) with three healers, a riposter, and only one hitter, Caedmon - and I didn’t have him last time around! How am I supposed to overcome Horghall’s ridiculous HP, Vivica’s heal and defense up, AND Boril’s riposte with a bunch of passive specials? Not sure. Guess we’ll find out Sunday!
