I was thinking some sort of zombie that rends or has a powerful bite once it has a hold of the target....give it a grapple check, if its grappling, it has an easier time (maybe auto hit?) biting? Maybe double damage? Something different.
This is something that just popped into my head....so don't bother telling me i'm crazy...I know that. My students tell me every day.
Opinions? grapple and then free hit or +4 perhaps? something. or a blood frenzy or something....similar to rage? Something to add on speed? Or should that just be the charge. Perhaps charge is best. Claws instead of slam attack?
