Hi,
I've noticed someone has the same thing happened in the Divinity II DKS in this forum: The bosses in some flying fortress are way too strong that they can kill me in a single magic blast or fireball.

My experience was like: Hard difficulty, level 32, magic resisitance is around 50%. The general Raze in his flying fortress killed me with a 600+ dmg magic blast at the first second of the battle. I tried to change to normal difficulty and it's the same. The second time I came across someone in the Broken Valley fortress and killed by a fireball with 1500+ dmg.

Is this designed like this? I need to level up to 35 or more and then come back again? I doubt this because I don't think I can win the battle even if I was level 40.

If this is a bug, I think it should be fixed.
