Yeah, with everyone saying how "easy" this game is, I was pretty shocked myself.
I didn't really do hardcore min/maxing (no custom champs), no tome scumming either. I did use crafting though.
Problem was she could heal back to full health in one turn AND kill one of my guys. The mountain men would kill units, feeding her dark avenger (up to 4 before I died).
I probably should have just focused her down hard with crowd control, except she one shot my champs and had enough action points to take down 2 people in one round. Nevermind the fact that she had body building 5, so it wasn't terribly efficient with a 90% resist. I guess I should have spammed it anyway to try to one round her. I didn't think she'd charge all the way to kill my mage in the back but oh she did.
She did about 1.8K dmg per normal attack (dark avenger 4)... of which I resisted 700 of it. Reflect worked nicely on her but doesn't matter. She can pop a +1800 healing item for 2 action points, and she has like 20 action points.
I was tempted to use earthquake which probably would have won me the fight except with the ooze nearby and candles, I probably would have just committed suicide that way by setting my own troops on fire. In hindsight, maybe that still would have been better.
I'm definitely not too crazy about re-starting yet again. Seems like the best option is pin point offense which is sort of what I was doing, but I'm curious to try a tank build too.
