Untouchable Minion (Nullimancy Magic)

You create a dark, intangible, and silent servant in the form of any medium or smaller creature you’ve encountered. While the figure can pass through solid objects, it must remain visible to you or the spell ends. The figure can move, fly, and communicate via visible motions without affecting physical objects, acting by your mental command. At any point in the spell duration, the figure can attack one target, who must make a Dexterity saving throw. A creature takes 1d6 force damage on a failed save, or no damage on a successful one. Once the figure attacks, the spell ends.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
