so i grinded illusion all the way up to unlock the perk that supposedly muffles all your spells from other magic schools, but bandits always detect me when i throw the fire charm at them
If you hurt them of course they will find you.
The silent casting only effects, directly casting it, sounds made by spell impacts still make noise.
I mean a "fire charm" sounds like it would hurt them, so ya of course they will become aware.
It doesn't make them ignore pain :o
If that is not what is going on the whoops
