my g/f plays a level 3 cleric who's not bad at turning but isn't spec'd for it, either. For Gerard Dryden's quest, she'd position her cleric by the door in each of the tombs, I'd run in and smash all of the sarcophagi and lead the train back to her. One hit, she vaporized like 8 or 10 undead - not just red-shirt skeletons, but dryden ancestors and those filthy archers, too. it was sweet.
with that spell, my paladin can actually turn undead like a real cleric! Nice, too, since he's usually running with eagle's splendor and a high charisma anyhow.
