Ironman notes
- Counts as a Slayer task from Vannaka (task: cockroaches). Killing it on task earns Slayer XP and points.
- Weak to earth spells: bring that style for faster kills.
- A herb source: it drops 11 kinds of grimy herb, useful for Herblore without farming runs.
- Drops crimson charm, gold charm, green charm and blue charms for Summoning pouches.
- It can also roll the shared rare drop table (gems, key halves and bulk supplies); luck items improve those odds.
