The Arms of Karmaetmanu are sentient severed black, and long arms. The arms have claws instead of fingers and a mouth filled with sharp teeth on the palm. There are white demonic symbols on the arms that allow them to be sentient and move on their own in search of human hosts. The arms work in pairs of four or three and their job is to find and attach to a human who is compatible with the blood of the Eldritch Horror Karmaetmanu. Once they have found a suitable human they will become Karmaetmanu
