Yes That has definately pissed me off to be on level 2 exp 1 and no more pet ghoul because he is trying to hit at -99 point chance on a shopkeeper. Even a cap between high level and low level characters (like if character level is greater than 7 then allow the ghoul to stay if its level is too low to hit the shopkeeper. Otherwise the ghoul can be called by a bell or whistle (or maybe any instrument) to leave the shop.
