concentration, 1 minute/mana
As two actions, you cause a creature that you can touch or see within 10 meters to imprison itself with its mind. The creature must make a Will saving throw. If the creature is immune to being charmed, the spell has no effect on it.
On a failure, it takes 5d8 psychic damage and you make the area immediately around the creature’s space appear dangerous to it in some way. You might cause the creature to perceive itself as being surrounded by fire, floating razors, or hideous maws filled with dripping teeth. Whatever form the illusion takes, the creature can’t see or hear anything beyond it andis restrained for the duration. If the creature is moved out of the illusion, makes a melee attack through it, or reaches any part of its body through it, the creature takes 5d8 psychic damage, and the spell ends.
On a critical failure, it takes twice as much damage.
On a success, it takes half as much damage.
On a critical success, it takes no damage.
You can increase the initial damage by 4d8 for each additional mana expended.
