This subclass is on the top of my to-play characters. The flavour in this is suberb, the idea behind it full of flavour, and the possibilities for strategic solutions to encounters -combat or not- are vast! Quite balanced, I might add, with only a few traps weighting in on a bit more powerful side. Not enough to really bother me, though. As a DM I would without a qualm let a player use this.
