Speaking of turning undead, I did some checking a while ago and noticed that there are very few easily turned undead creatures in the MM - compare the CRs to their HD+turn resistance, and the cleric will have a hard time turning any but the weakest undead (Medium or smaller skeletons and zombies). I'm thinking that it might be an underpowered ability but I'm not going to change it yet, because
(a) I haven't seen it in use very much yet, so the theoretical weakness might vaporize in actual gaming, and
(b) It's not like the cleric class needs a power boost.
