This spell has some pretty cool flavor to it. The Big Bad Evil Guy sacrificing helpless creatures to gain power is pretty iconic.

My question is on the mechanical effect. I have a player that memorizes this spell 2-3 times a day to make sure his enemies are for sure passed-on to the other side. This last session, he used it twice in a row at the end of an encounter.

This led to a debate as to whether or not he gains an additional +1 to his Caster Level for the second casting of the spell.

The enhancement bonus to strength doesn't stack for sure, the temporary hit points you only get the highest amount rolled, but the caster level doesn't have a bonus type associated with it, so I'm confused.

Would this player get +2 caster level from two separate castings?

No. Think about the balance issues that this could lead to (hint: picture a large bag full of nearly-dead hamsters.) More to the point, there's a general rule that even 'untyped' bonuses do not stack if they come from an identical source (in this case, death knell.)

Exactly what I told my player. The potential for insanity is quite apparent. Can you site that source please?

Tough call. The only limitation I think you could apply is the, "Special Bonus Types" from the CRB which states:

Bonuses without a type always stack, unless they are from the same source.

Turns out it wasn't so tough once I looked it up.
