whatever you do...DON'T take him into your party and do that quest! He takes you directly to the Temple of Elemental Evil..and trust me...he has..lackys there that are not so easy to beat...yeah, they have relatively low hit points but there are like 20 of them in this one tiny room! So if you value your LIFE don't do that quest yet...just kill him! hehe..you get more out of it that way.

ps..i came back to do that quest after going through Nulb..yeah..at a level 4 and it was still hard...there really wasn't much to do in Nulb surprisingly...i think that town was severely edited...not to meniton you find a gay guy hanging out on the streets that can join your party and the people talking about the brothels and your character being able to trash talk the wenches in the bars...all of this though i thought was pretty funny..haha...that's me for you!
