Ironman notes

  • You need 20 Slayer to damage it, so plan the Slayer levels before the trip.
  • Counts as a Slayer task from Mazchna (task: rock slugs). Killing it on task earns Slayer XP and points.
  • Weak to water spells: bring that style for faster kills.
  • Drops 9 kinds of seed, which keeps farm patches stocked.
  • It can also roll the shared rare drop table (gems, key halves and bulk supplies); luck items improve those odds.
