Psychic Crush (HB)

You exert the full force of your will upon a creature you can see within range. It must succeed on a Strength saving throw, taking 5d8 force damage on a failure and half as much force damage on a success. It must repeat this saving throw at the end of each of its turns, taking 2d8 force damage on a failure, and ending the effects of this spell on a success. If this spell reduces a creature to 0 hit points it is crushed into a flesh-colored ball, roughly the size of your fist.

At Higher Levels: When you cast this spell using a spell slot of 6th-level or higher, each instance of force damage it deals increases by 1d8 for each spell slot level above 5th.
