I dig city-fey, and this makes a nice (dark) complement to the lantern fey or whatever they're called.

I can imagine the City-port (not a great name, though) and Daylight Camoflage working beautifully together to create a very hard-to-catch critter. Also, Scent of Poverty is oddly hilarious to me. Good luck, adventurers, trying to find one of these guys with all our hundreds of thousands of golds in equipment.
