Ironman notes

  • You need 72 Slayer to damage it, so plan the Slayer levels before the trip.
  • Counts as a Slayer task from Jacquelyn, Raptor, Vannaka, Duradel, Kuradal and Laniakea (task: skeletal wyverns, undead and skeletons). Killing it on task earns Slayer XP and points.
  • Weak to fire spells: bring that style for faster kills.
  • Aggressive: it attacks on sight, which is handy for AFK kills once your gear outclasses it.
  • A herb source: it drops 11 kinds of grimy herb, useful for Herblore without farming runs.
  • Drops 14 kinds of seed, which keeps farm patches stocked.
  • Drops crimson charm, gold charm, green charm and blue charms for Summoning pouches.
  • Always drops Wyvern bones: Prayer XP as you go.
