Well, we'll see what he'll allow and when. I suspect he might find the knowledge devotion from a cloistered cleric more acceptable than from a regular cleric, just because the character's so stupid and belligerent. Easier to believe this stuff was drilled into his head by a training regimen that doesn't give you a choice, than that it was a choice he made on purpose and then abandoned.
I gotta sleep, though. Thanks for the input.
