King Tut
I'll go after the undead tailor, or whomever appears to be charming the PCs. I hate charm spells.
IQ check 3 (made by 8 or so) to figure out who's doing the charming.
BR: 10 (not sure what that hits) to try and hit him with the band saw.
What are the chamed PCs doing? Making another undead enemy, or injuring themselves? If they are making another enemy, how close are they to be being done? How do you break charm spells, by attacking the charming person?
