One of my first BG1 characters was a Cleric. I never finished the game with him (got to Ch. 5 then computer got whiped out with a virus

), but he did very well. He would have been MUCH better had I dualed him from a Fighter though... If I could do it again I'd probably dual him over at level 3 and put 3 stars into blunt weapons and 2 stars in slings.
