The elegant assassin
So kids, remember to check if the skeletal thing trying to tear off your face is cloaked or uncloaked!A dusanu looks like a mold-encrusted skeleton in a tattered cloak; I presume the tattered cloak is standard issue, and is given to all dusanu.
At 9 HD, dusanu are a nasty trick to throw at players expecting simple 1-HD skeletons, and with an Int of 10 they're more than capable of laying ambushes and setting traps. They have a built-in reason to go after PCs, since that's how they propagate. All in all, I like 'em.
