Why? To qualify for ScM early.
Anyways, I'm guessing the latter is the easiest. If the means to the (latter's) achievement is via a (cheap =< 900 GP) item, I'd be ecstatic. Otherwise, it'd have to be a feat whose effect remains for at least one level to be retrained, Psychic Reformed, or DCFSed.
On that note, anyone mind giving me the price of those 3 tricks off-hand?
