Description
3rd-level evocation


 * Casting Time: 1 action
 * Range: Self (30 foot cone)
 * Components: V
 * Duration: Instantaneous

You unleash a destructive wave of mental power in a 30-foot cone. Each creature in the area must make a Dexterity saving throw. On a failed save, a target takes 5d8 force damage, is pushed 20 feet directly away from you, and is knocked prone. On a successful save, a target takes half as much damage and isn't pushed or knocked prone.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
