Ironman notes

Counts as a Slayer task from Jacquelyn (task: rats). 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.
Always drops Bones: Prayer XP as you go.
