Unruly Magic

You conjure forth and fire an orb of unruly magic at a point you choose within range. Any enemies between you and that point must make Dexterity saving throw to avoid the orb or take 8d6 force damage. Once the orb reaches the point it explodes into smaller orbs that bounce around in an area. Each creature in a 15-foot diameter sphere centered on that point must make a Dexterity saving throw or take 3d6 force damage, or half as much damage on a successful save. The mini orbs continue to bounce around inside the sphere until the start of your next turn. Any creature that starts its turn in the sphere or moves into it for the first time on their turn must repeat the saving throw.

At Higher Levels: When you cast this spell with a spell slot of 6th level or higher, the force damage of this spell increases by 1d6 for each slot level above 5th
