Source: Rewarded randomly when using 5 Animated Particulates received from the Talos of Gaia during the Anniversary Event. The Shem of Swarms will only appear as a possible pet through Animated Particulates after having faced the Swarm Talos at least once.
This Pet cannot be traded or sold on the Auction House.
Covered in scabrous growths and an accumulation of what looks to be all forms of venereal disease, the question is why anyone would want it as a pet?
