Most conflicts - with humans or animals - involve posturing and threats, not just actual combat.
Monster attack tables should have one option that is binary - involves either threatening behavior (snakes hiss, lions roar etc), not a damaging attack OR if the monster has taken damage in prior rounds, it attempts to flee.
This means monster combat is not just a guaranteed hit everytime. Of course some mobs like undead should ignore this and just have a relentless list of attacks
EDIT: Also, more monsters please!
