desecrated tentacles attack in a 2 space line and their health and defense as well as aggressiveness scales depending on what enemy was used to create them as well as them being immune to injuries and only taking 1 sta to create they can usually keep most distracted while you pick them off one by one and continue adding more tentacles to the mix also 10 sta is an obscene amount of stamina to be spending on something thats going to get promptly messed up again consider the highest stamina cost in the game for weapons is the saint sym at 5 sta or the great sword at 6 sta with a full spin attack
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.
