Ravenous vampyre

The Ravenous vampyre appears at Fairy ring in the Haunted Woods east of Canifis when the player is on a Slayer challenge assigned by Mazchna or Achtryn. For the challenge, the player must be near the ring and must contact Mazchna or Achtryn using an Enchanted gem. The monster will then drop from the sky into the centre of the ring and attack the player.
