Yeah, I got nothin' for you there.
Thanks! I figured that he should be against divinations, though it does seem that one caveat would be appropriate. Should a follower of Tesolk be in the act of guarding a secret and in need of magical means of protecting it, certain divinations (likely see invisibility and detect lies) are allowed.That is absurdly cool, if I do say so. Make him ridiculously anti-divination.
Also figured he'd be against blackmailing and opening locked doors, the latter being a minor sin that a worshiper can easily ignore in fellow PCs.
