Brimhaven Dungeon resource dungeon

The Brimhaven resource dungeon was released on 19 July 2010. This resource dungeon has a Dungeoneering requirement of 80 to enter and the entrance is on the west wall of the iron and steel dragon area. The first time you enter you will receive 12800xp.

Getting there
Players will need 875 coins to enter the Brimhaven Dungeon, unless they have completed the hard Karamja Diary and are wearing Karamja gloves 3, which will grant free access. A hatchet is required to chop through the roots along the way, and dragonfire protection is strongly advised because the entrance to the resource dungeon is guarded by dragons.

Inside
The resource dungeon contains iron dragons, steel dragons, a hammer spawn, and an anvil, which allows players to smith the bars dropped by the dragons into stackable equipment. This dungeon is largely reserved for high level players due to its requirement of 80 Dungeoneering to access.

The dragons in this dungeon appear to be spaced farther apart than in the main dungeon which potentially slows down killing speed.
