Resource dungeon

Resource dungeons (also known as Surface Dungeons) are dungeons requiring a minimum Dungeoneering level to enter, and which give a one-time experience reward for discovering — along with other resources. These resources include new monster spawns such as frost dragons and mining rocks, trees, and herb spawns. Note that while an experience bonus is given for finding a dungeon, Dungeoneering tokens are not awarded to match the bonus. This is similar to using experience lamps or penguin points to train Dungeoneering, as neither of those methods award tokens either. Finding all sixteen currently released dungeons gives a total one-time experience reward of 100,000 xp, or 12,000 xp for non members.

Effect on economy
A large amount of rare resources were introduced to the economy as a result of these dungeons. A lot of these items suffered a price drop such as limpwurt roots and almost all herbs and ores such as runite ore. Maple logs didn't suffer from the new dungeons as much, most likely because members powerchop those, and they are available in bulk from managing Miscellania. However, players with high dungeoneering are likely to have high opportunity costs compared to other players, and do not spend extended periods of time harvesting commodity resources, so the economic effects of high-level resource dungeons are limited.

Dungeons
There are currently a total of 16 resource dungeons. These are all accessible as soon as the required level is reached, except for the Braindeath Island 'Rum'-geon, which also requires the completion of a quest, A Clockwork Syringe, and the Dwarven Mine resource dungeon in the Mining Guild which requires 60 Mining, and the Baxtorian Falls resource dungeon which requires Waterfall Quest to be started.
