[@Aristo] Well, he's got a giant morningstar to clobber people with, so I'd say he'd be more of a melee combatant rather than a caster chilling in the backline! :lol 

Seriously though, I'm a fan of a more subtle approach to magic (yes, even in D&D) so I was thinking he wouldn't have all those flashy Cleric spells you normally see. He's more about prayers, rituals, breaking curses, that sort of stuff; the more overt use of his powers would be against the undead and perhaps some healing since Kelemvorites are apparently good at that, but that's about it. So if you want to rain down fire and brimstone on the nonbelievers, by all means go ahead and roll a caster.
