the half fey is spot on. (charm person at will, wtf)
hafta look up trapfinding 1/30th. unless you mean casters are better trap finders than trapfinders.
Ghost 1 (im not really 100% up to speed on savage progressions, but i think that trades all that horrible ghost LA for 1 level?) does pretty much replace a whole prc.
i think we have a dip handbook, that sorta mixes with the stuff im interested in. but, for example, Fighter 1/2/4 isn't really a complete mechanic or progression.
