Dark Magic Attack

A bright streak of purple light flashes from your pointing finger to a point you choose within range and then blossoms with a low roar into an purple explosion of magical light. Each creature in a 25-foot-radius sphere centered on that point must make a Wisdom Saving Throw. A target takes 8d6 Psychic Damage on a failed save, or half as much damage on a successful one.

Creatures caught in the blast must make another Wisdom Saving Throw. On fail the creature is Stunned.

 (Wisdom Saving Throw Has To Be Greater Than 15)

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
