Animate Crawling Claw

You revive a murderer's hand as a crawling claw. You may use your bonus action each turn to command the claw, and it will follow each command to the best of it's ability. Comands must be simple, and cannot rely on recognition.

For example: "Kill all who try to enter this door" works, but "Kill all who try to enter this door, except party members" does not. 

You can only have 1 crawling claw under your control this way, unless you expend a higher level spell slot.

At spell level 2 or higher, your max crawling claws increases by 1 per spell level beyond the first.
