Ironman notes
- You need 96 Slayer to damage it, so plan the Slayer levels before the trip.
- Counts as a Slayer task from Raptor, Kuradal, Morvran, Laniakea and Mandrith (task: acheron mammoths). Killing it on task earns Slayer XP and points.
- Weak to stab weapons: bring that style for faster kills.
- Drops green charm, crimson charm, gold charm and blue charms for Summoning pouches.
- Always drops Big bones: Prayer XP as you go.
- 7 of its drops come noted, so they don't fill your inventory.
- It can also roll the shared rare drop table (gems, key halves and bulk supplies); luck items improve those odds.
