Oops. Changed. Takes one Ki use and a standard action to activate, although I'm pondering making it a full-round one.
What do you mean the Taijutsu line?The list looks good, maybe you could make the Taijutsu line Fighter feats as well? That seems reasonable, considering Improved Unarmed Strike already is.
I'd suppose it'd apply to that. Will mention.Edit: Also, the Armor feat is good and balanced, but you didn't mention if it applies to touch AC and flatfooted (I assume it does but...).
