Can anyone advise how I blat the gnomes demon in the underdark? I`ve hit him with everthing I`ve got and can`t make a mark on him. Two of my characters have swords of celestial fury and neither has managed to mark him yet. I keep being told that there`s `no effect`.
I`ve tried magic but to no avail.
He`s really getting on my nerves.
Cheers

Simply cast Protection from Evil on your party and he should ingore you while you attack it, he requires about a +3 weapon to hit.

i changed into the slayer thing

If you get the message "no effect" try using a different type of weapon

I found that the cleric spell Bolt of Glory works quite well (it does 10D6 damage to demons)

just set about 15 traps and hes dead meat
