Killing 'rum'-pumped crabs

By having the surgeons trapped in the other room, you can easily deal with the crabs.

'Rum'-pumped crabs are mutated crustaceans found in the 'Rum'geon on Braindeath Island. They have been injected by Captain Donnie's general malpractitioners in order to create an army. They are the only monsters that drop the brackish blade.

In order to access the dungeon, the quest A Clockwork Syringe needs to be partially completed and the player must have a fishbowl helmet and diving apparatus equipped, otherwise they will not be allowed to enter.

'Rum'-pumped crabs use only melee with a maximum hit of around 240. They will constantly be considered aggressive towards anyone within the 'Rum'geon. They will take increased damage from the brackish blade that they drop, as well as the brine sabre.

TriviaEdit

  • Before the Evolution of Combat when the special attack of the brine sabre and brackish blade was used on a 'Rum'-pumped crab the message "The Brine Sabre/Brackish Blade seems super-effective." appeared. This may have been a reference to Pokémon where a player would see "It's super effective!" when a Pokémon was hit by an attack that it was weak to.
  • Killing a 'rum'-pumped crab is required to complete the Alcrabholic task in the Daemonheim task set.
  • Despite requiring a Slayer level,'Rum'-pumped crabs are not a slayer assignment.
  • Despite being a crab, they used to drop bones. This was rectified on 1 July 2014.
