Braindeath Island 'Rum'-geon

The  'Rum'geon  is a resource dungeon locared on Braindeath Island unlocked during A Clockwork Syringe that contains 'Rum'-pumped crabs and General Malpractitioners. Since the 'Rum'-pumped crabs can't be found anywhere else in the game, this is the only area in the game where players may obtain Brackish Blades.

You need level 50 Dungeoneering to be able to access the 'Rum'geon, which is one of the requirements in order to start the quest. This resource dungeon is not mentioned in the in-game Dungeoneering guide.

You need a diving apparatus and fishbowl helmet to access this dungeon. Because of its underwater state, Dwarf Multicannons cannot be used here.

Summoning familiars and Summoning pouches are not allowed into the dungeon.

This is the largest resource dungeon so far, and also contains a "Strange wall" at the northern wall of the northern most room, like normal Boss rooms have. This wall cannot (as of yet) be opened to reveal an exit.
