Ironman notes

Counts as a Slayer task from Raptor, Kuradal, Morvran and Laniakea (task: gemstone dragons and dragons). Killing it on task earns Slayer XP and points.
Immune to stuns.
Aggressive: it attacks on sight, which is handy for AFK kills once your gear outclasses it.
Drops green charm, blue charm and gold charms for Summoning pouches.
Always drops Reinforced dragon bones: Prayer XP as you go.
It can also roll the shared rare drop table (gems, key halves and bulk supplies); luck items improve those odds.
