Durlag's Tower Demon Knight

JitterBug

The Demon Knight's spell (power word stun) has no way to resist it no magic resist, saving throws or even as how the spell is said to work in BG2 hit points over 90. My character has 136 hp at level 8 and I used him to solo the demon knight after some irritation and confusion over this spell I changed tactics. When he cast it I have over 100 hp left not below 90 even though I think (not sure) that its max hp that affects it even if that were the case he uses it on me when I have over the 90 hp immunity and it effects me no matter what. In the end I beat him solo though not the way I wanted. Won by using a scroll of magic immunity and rushing up next to him so he couldn't cast spells or I receive any and traded blows til I was victorious.

The demon knight does not use the standard wizard spell "Power Word, Stun", he uses a special innate ability version of it, which does not have hp restriction. I imagine it works as originally designed, since this content was created before BG2 with its high-level spells was released.

I figured that was the case since the spell wasn't usable in bg1how ever they expanded on the rules for it in bg2 so I expect the spell should adhere to them in bg1.
