In DnD, magic missile always hits and as you level up, there are more of them. Never Winter Nights was a weird game, they didn't balance it well. Finding stuff was impossible, I still beat it though... Druid had stone skin in NWN, it was useful.
Muds sound fun, I created a semi-one a while ago, but it was brief and didn't work to well.
You'd be better off with a control demon spell or banish...It was a completely horrible spell. It was like a hold person for 1 round with like +500 bonus to save spell... plus it doesn't work as well on other races as they "don't understand your humor". So I doubt the demons would be amused.
I agree with a previous post, I'm dumber for reading this.
