As two actions, a creature that you can touch or see within 18 meters must make a Will saving throw. Creatures immune to being charmed automatically succeed on the saving throw.
On a failed save, it takes 5d8 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 5d8 psychic damage, and the spell ends.
On a successful save, it takes half as much damage and the spell ends.
You can increase the initial damage by 5d8 for each additional mana or psi expended.
