With 10 stamina you've an ally as strong as a city guard who can automatically jump on ennemy, it's far from a promply messed pnj. For 50/60 staminas I usually wipe out any band of bandits and sirens can even solo orcs. But if it's not enough, as a deepone you can kill them with range spell who are quicker than arrow while dealing as much damage and as all ennemies are sexually attracted by you, when they'll spot you they will usually masturbate instead of fighting you at least until you attack them.
