Hey guys I am not a speedrunner, but I found a glitch maybe it can help you. I was able to recreate it twice (this is the second attempt, unfortunately I didn't record the process, after that I had no luck. Basically I tried to stealth myself through a camp with two trolls with the invisiblity spell and they killed me. When I loaded the game again after my death I was invisible for every single enemy, even if I attacked them. It worked only at the main area where I died, as soon as I entered a building-school-hidden passage which requires loading the glitch went away.

The main question is can you petrificus totalus them? Because that does a huge chunk of damage, and if you can do it multiple times, that's a possibly optimal strat for big enemies or difficult mobs

yes you can, here is my another footage sorry for the audio I didnt realize my ps5 controller is recording the random youtube shit going around in the room
