Dreamshatter Orbs

You create 6 orbs of pure nightmare or ecstasy that orbit around you for the spell’s duration. When you cast the spell — and as a bonus action on each of your turns until all the orbs are spent — you can send 3 of them streaking directly toward a point or points you choose within 100 feet. When an orb reaches its destination, or impacts a solid surface, it erupts in a 5-foot-radius sphere. Each creature within that sphere makes a Charisma saving throw. On a failed save, the creature takes 2d4 Psychic damage and its speed is reduced by 10 feet (20-foot maximum) until the start of its next turn, or half as much damage and no speed reduction on a successful one.

Using a Higher-Level Spell Slot. You can create one additional orb, and expend one more orb per turn, for each spell slot level above 3.
