Guthix balance potions and flasks are used against frozen Vampyre juveniles, Vampyre juvinates or Vyrewatch. After freezing a vampyre with the Rod of Ivandis or Flail of Ivandis, the usage of the potion has three outcomes: the vampyre will be destroyed, the vampyre will become angry (+10 combat level, but vulnerable to all attacks), or they will be returned to human form. Using it on a held Vyrewatch will simply deal a random amount of damage. If the full, 6-dosed version of this potion is consumed, each dose would cost about coins.
