Any advice on this fight? Can't seem to beat it.

absolute hellish though, i won on easy settings.
the objective is not winning but surviving it use summoning spells as cannon flooder

don't think you can tank this guy you will not

yeah, I can win on easy and story, but normal and above seems impossible with my current build. I noticed that it says "survive" in the quest. So you don't have to kill him? How many rounds do you have to last?

not sure think it was 15 turns or something

Thanks. I'll try to wait it out during my next playthrough.
