As an action, you create a dense swarm of silver shards in a 10ft sphere in an unoccupied space within range. Any creature in the spells area must make a dexterity saving throw, on a failure taking 6d6 slashing damage. As an action on your subsequent turns, it can be split into smaller clouds, as a bonus action, you can move any of the clouds up to 10 feet in any direction. On it's first separation, the main cloud splits into 2 clouds dealing 3d6 slashing damage in a 5ft radius on a failed DEX saving throw. The main cloud can be split in up to 6 smaller spheres, each dealing 1d6 slashing damage in a 5ft radius. The damage is considered silvered for the purposes of overcoming resistances.

Higher Level Cast: For every level above third, a further 1d6 can be added to the damage output, with a corresponding increase in the number of spheres that can be made out of the initial cloud.
