Xavius toenails

Said to be an ultimate artifact of great power, Xavius's toenails were created when Grom Hellscream himself re-banished Xavius to the Emerald Nightmare. They really keep him grounded.

It is said that if anyone were to pull out a Xavius Toenail, they would be crowned the next great king of Azeroth. Also, they'll have good luck and 72 virgins for the rest of their mortal lives.
