argh. well, apparently only the standard familiars don't have "attack" default scripts. i tried the mind flayer and as soon as i turned the ai on it stunned my entire party and ate several brains before i could hack it into oblivion. also its stun ability isnt a spell or innate that it possesses, rather it's coded into the CRE's script, so you'd have to alter that and really, that's alot of trouble.
since that didnt work out too well, i did it with ribald, and now ive got a portable store. very handy
