Book of shadows: Claws of Velsharoon

The secret of this relatively simple necromantic rite can be found in both the Art of Necromancy and the Book of Shadows (for the wizard version) and also the Nycoptic Manuscripts (for the priest version). After the severed limbs have been assembled, up to one claw may be animated and control per level of experience of the spell caster (to a maximum of 20) if you cast the spell exceeding the amount you can control the spell instantly fails. Once created, crawling claws can be directed by the telepathic commands of their creator as a bonus action, but more often, they are given simple duties, which there simple intellect (or complete lack thereof) could follow.

The ritual invoked to create a crawling claw works best with a hand recently severed from a murderer. If a dead murderer’s spirit already manifests as another undead creature, if the murderer is raised from death, or if the spirit has long passed on to another plane, the ritual fails.
