For me it's Geshniz and Ba'al. I'm level 34, over 40 magic resist, 960 hitpoints and both of them or their minions kill me instantly. There is zero chance to avoid. Ba'al shots a magic blast to start the fight and it does more than 1000 damage, Geshniz changes me into a beetle and his minion kills me instantly with a firebal with over 1200 damage.
I've killed Stone, Raze, Kali and many other bosses without such problem.
I have bought the game on Steam and it shows version 1.4.9.70 on the botton right side of the menu screen.
All my saves are after the bug had hit me, I don't have any means to load before that and going in and out of the dungeons, doing other things and returning does nothing, they keep hitting me with their over-1000-magic.
Edit: Another minor bug (completely unrelated) is that the music "Rambler for Slavs" that you can order the guy in your throne room to play, stoped working. Whenever I order him to play that music the game just ignores and keeps playing the music that was playing before.
