1-level Necromancy (ritual)
Choose the hand of a creature that has been severed from its body for longer than 24 hours and grant it sentience. For the duration of the spell, the creeping claw (MM pg.44) is under your control and can be commanded using your bonus action. The claw can only understand simple commands.
The claw is under your control for 1 hour, after which it stops obeying you. To reassert control for another hour or to assert control over an existing crawling claw, you may cast this spell again.
If the claw is still alive when the spell ends, it will attempt seek to reunite itself with its rightful If its original owner is dead, the claw will wander off purposelessly.
