...without necessarily killing people? My rep has gone up to 18 and i think i'm about to lose viconia who i want to keep. the only thing i can think of is to turn into the slayer and lose 2 pts that way. i want to keep my rep between 14-16 in the interests of party balance. i thought of stealing too.
any suggestions...

Steal

it the only thing i can think of
and bringing back valygar to that crowling waizard will lower your rep with one

i ended up turning into the slayer and kicking some goblins asses
brought my reputation down to 16 which is where i want it to be
in future i might try stealing
