Dorea's Daunting Dead

From the ground you pull six skulls, that start circling around you and stay there for the spell's duration. As soon as you cast the spell, as well as the turns thereafter, you can use a bonus action to send one or two of the skulls hurtling towards an enemy or location with a range of 120ft. When it reaches its destination the skull explodes. Any creature in a 5 feet radius of the skulls explosion must make a Dexterity saving throw. On a failed save the creature takes 2d6 necrotic damage, or half as much on a successful one.

At Higher Levels. When you cast this spell using a spell slot of level 4 or higher, the number of skulls pulled from the ground increases by two for each spell level above 3rd.
