very annoying glitch on the boss room of floor 11 where the boss would be invulnerable at ALL times, not attack, and just chase me around the room slowly. I wanted to see what would happen if I let him catch me. So he just pushes me as he walks around (still not attacking). Eventually, he trapped me in a corner of the room and I was completely stuck... had to restart my run :(
Which spells did you use? Do you play with spells or melee combat?
