I only used him once. He died, permanently, about 3 seconds after emerging from the cave from Mulahey's lair into the deserts. So, I can't say I've given the fellow a fair shake. Maybe if he'd been given a Moonsling, so he wouldn't charge forward like a scrawny Minsc and attempt to poke the guy in plate mail...
Maybe next time I run through, I'll try him again, and determine exactly which of us is goofy in the head.
