Vecna's Ire

A sicking green orb appears in the palm of your hand showing visages of faces in torment. you choose a point within range that then blossoms with a multitude of voices wailing in torment. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 6d6 necrotic damage on a failed save, or half as much damage on a successful one.

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