I agree with the poster above, you need to dramatically up the prereq's for this. A character could get into this PRC at 3rd level and lose NOTHING. I'd up the skill requirements to at minimum 10's and probably throw a feat (spell focus: necromancy, Extra Turning) or class requirement (turn or rebuke undead as a 5th level cleric?) in there for good measure.

As it stands, this is brokenly good.

Also, you might want to use the code for tables and Prc's Fax Celestus was nice enough to provide us all on this thread.
