Ironman notes
- Counts as a Slayer task from Jacquelyn and Vannaka (task: cave slimes). Killing it on task earns Slayer XP and points.
- 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.
- It can also roll the shared rare drop table (gems, key halves and bulk supplies); luck items improve those odds.
