I didnt mind them i just used spells that hit lots of times to tick em down fast like i dumpped the concentration blade cloud on them then took out the minions, like one boss had sanctuaryed minions i assumed to eat n get more powerful so i just used concusion grenades and kocked em out of the map before they could be eaten, or used the force push on the warding glyph
I only lost 1 fight in the game and that was the boss i didnt know what 1 mechanic did n it wiped my whole party , i was sorta waiting to see what it did so had to do that fight again lol
But on second run i killed the last boss in 2/3 turns 1 tun to get party in the spoty to get to second form i then dumped a globe of invulnerable on my party untill second form was ready ) and 1 round to kill the boss (the ones with the unstoppable mechanic where more intresting imo)
