Collect Dust

You use necromancy to collect the dead skin cells of a freshly-killed creature. After casting this spell, the skin cells gather in a grey cloud. It will always stay within 100ft of you. On your turn, you can spend a turn to command it. You can command it to do one of these actions:

MOVE: It can move up to your speed minus 10ft. It also can move upwards.

SWARM: It can surround a target that is within 5ft eyes to blind it. So long as the target doesn’t have blindsight, the target is now blind. The cloud moves with the target until your next turn, when, if you don’t spend your turn to command it to use swarm again, it doesn’t blind the target. The target cannot, unless it destroys the cloud, swat the cloud away.

ATTACK: The cloud can target a creature within 5ft and attack it. The cloud can either instantly hit the creature with 1d4 bludgeoning damage, or make an attack roll with + your proficiency bonus and, on a hit, deal 1d8 bludgeoning damage.

The cloud has 15HP and an AC of 10 + your proficiency bonus. It has immunity to bludgeoning, piercing and slashing damage. It is weak to fire damage. After a day, the cloud floats away and can’t be commanded. It can’t have any conditions.
