Held Vampyre juveniles are Vampyre juveniles that have been bound by the special attack of a Rod of ivandis or Ivandis flail. In order to defeat them, players must use a dose of a Guthix balance on them. When the potion is used, one of three things can occur: The vampyre dies instantly, the vampyre becomes angry and gains combat levels and life points, or the vampyre turns back into a human and rewards the player. If you continue to attack the vampyre withough using a dose of Guthix balance potion the held vampyre juvinate will turn into Mist.
