Now i am with professor know everything yet nothing on a lil tower quest and the
petrificus totalus refuses to work...

you need to be quite close to the enemy for the prompt to appear. Also invest in the aoe version once you get it working as its very fun to petrify multiple enemies at once.

Close & directly behind them, it's kind of finnicky at times because sometimes the enemies will have some weird rotations even doing a full 180 degree turn briefly then back to normal and still walking

Good Luck & Have Fun
