concentration, 1 minute/mana or psi

As an action, you attempt to bind a creature within an illusory cell that only it perceives. One creature that you can touch or see within 18 meters must make a Will saving throw. The target succeeds automatically if it is immune to being charmed.

On a failed save, the target takes 3d8 psychic damage, and you make the area immediately around the target’s space appear dangerous to it in some way. You might cause the target to perceive itself as being surrounded by fire, floating razors, or hideous maws filled with dripping teeth. Whatever form the illusion takes, the target can’t see or hear anything beyond it and is restrained for the spell’s duration. If the target is moved out of the illusion, makes a melee attack through it, or reaches any part of its body through it, the target takes 8d8 psychic damage, and the spell ends.

On a successful save, the creature takes half as much damage and the spell ends.

Augment

You can increase the damage by 4d8 for each additional mana or psi expended.
