Archmage's Hands

Spectral, floating hands appears at a point you choose within range. The hands last until you dismiss them as an action or fall unconscious. The hands vanish if they're ever more than 30 feet away from you or if you cast this spell again.

You can create a number of hands equal to your intelligence modifier halved, and can control any number of them as a bonus action. The hands are more dextrous than before and can perform any task that you could perform with your own hand and while you control the hands you can use one to make a melee spell attack to a target within 5 feet of it, dealing 1d6 force damage on a hit.
