Ironman notes
- Weak to water spells: bring that style for faster kills.
- Aggressive: it attacks on sight, which is handy for AFK kills once your gear outclasses it.
- Drops gold charm, crimson 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.
