'Rum'-pumped crab

'Rum'-pumped crabs are level 91 monsters found in the 'Rum'geon on Braindeath Island, which is a multiway combat zone. They are the only monsters that drop the brackish blade. In order to access the dungeon, the quest A Clockwork Syringe needs to be completed. In addition, a Fishbowl helmet and Diving apparatus must be worn, otherwise the player will not be allowed to enter. They use only melee, and hit a maximum of around 120. They will take increased damage from the brackish blade that they drop, as well as the Brine sabre. Protect from Melee is advised, as multiple crabs will attack the player. On occasion, nearby level 65 general malpractitioners may throw a syringe at a crab and temporarily increase its attack speed, up to a maximum of 8. The malpractitioners will also attack the player with poisonous ranged attacks, so Antipoison potions or an Anti-poison totem will come in handy. Additionally, these monsters are weak to stab attacks.

Trivia

 * When using a Brine Sabre on them, the player will get a message: "The Brine Saber seems super-effective.", instead of -re.
 * When being randomed underwater, the person (e.g. the Mysterious Old Man) will appear wearing diving equipment. The same applies to the genie if you choose a lamp from the box.
