Ironman notes

  • You need 92 Slayer to damage it, so plan the Slayer levels before the trip.
  • Counts as a Slayer task from Raptor, Morvran and Laniakea (task: dragons and nodon dragonkin). Killing it on task earns Slayer XP and points.
  • Weak to water spells: bring that style for faster kills.
  • Always drops Dragonkin bones: Prayer XP as you go.
  • 8 of its drops come noted, so they don't fill your inventory.
