Before even downloading b20 I wanted to have some more fun with my b19 mindslayer winner.

I always wanted to kill these lvl50 unique npc in towns, and so I happened to find myself slaying these lowish mages in Anglowen before facing Linaniil...

After hitting her for some thousands of damage without taking any real damage I started to wonder if she is invulnerable, then I hit her some more.
