OK, I've read up on the archetype and don't see any problems with it, and so far nobody has posted any abuse-worthy concerns, so I'll assume it's a relatively un-munchkinable archetype.
What about monks in general - can a clever player find combos of class abilities, feats, traits, magic items, spells, etc., that can be system breaking? Are there well-known combos I should watch out for?
Also, are there any traps that the player should watch out for? You know, those abilities that seem awesome but turn out to be really bad choices?
Thanks again.
