So last night I threw a vampire monk at the PCs. Aside from being hilariously sadistic (3 attacks with flurry of blows + 2 negative levels per natural attack + spring attack + mobility + DR not breached by their weapons + etc. = best challenge ever), it also produced an amusing discussion over how much of his mookery was from vampire powers and how much was from monk powers, leading to:

"No! He has turn resistance because he's a vampire, not because he's a monk! Monks don't have vampire resistance! ....wait..."

I stand by the truth of my statement, however.
