You call forth a wave of psychic energy, each creature in a 60ft cone must make an Intelligence Saving Throw. On a failed save the target takes 4d8 Psychic Damage and is stunned until the start of your next turn. On a successful save the target takes half as much damage and is not stunned.

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, and you may choose to exclude one creature from the effects for each spell level higher than 3rd.
