Resource dungeon

Resource dungeons (also known as RDs, ResDgs, and Surface Dungeons) were released July 19, 2010. Each dungeon requires a minimum Dungeoneering level to enter it, and will give a one-time experience reward for discovering it — along with other resources. The dungeons add many new ways of training Woodcutting, Mining, Prayer, Herblore, and combat skills. These resources include new monster spawns such as Frost dragons and new Mining rocks, Prayer experience in the form of Frost dragon bones, trees, and herb spawns. Note that while an experience bonus is given for finding a dungeon, 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 fourteen currently released dungeons gives a total one-time experience reward of 86,600 xp or 12,000 xp for non members.

Trivia

 * Resource dungeons were first mentioned in the May 2010 Developers' Blog Beyond the Release and mentioned again in the July Behind the Scenes update.
 * The Behind the Scenes stated that "there are more than fifteen" resource dungeons, but the initial release included only fourteen. Mod Emilee stated that they put the wrong number.
 * On release, the Knowledge Base said that the volcano dungeon's contents were "Implings" and that Lesser demons were the only monsters in there. In fact, Implings are not in there at all and Imps are the other monster with the Lesser demons.
 * Most resource dungeons lacked music upon release, but all of them now have music as of July 22. The Daemonheim resource dungeon still lacks music, although this may be intentional.
 * With the release of these dungeons, players could now cut maple logs on non-member worlds.
 * The Frost dragon and Frost dragon bones became available to members with level 85 dungeoneering outside of Daemonheim with this update. Frost dragon bones were released on the Grand Exchange at a starting price of 20k and give 180 Prayer xp per bone, making them the highest level bones to train prayer.
 * In each and every Resource Dungeon, there is a strange pillar located within the dungeon. Many also have water features or deep pits.
 * Although they are called dungeons, they are not labelled with the dungeon entrance icon on the World Map. This is because they are supposed to be somewhat hidden.
 * There are now 5 runite rocks available to non-members, and those released with this update are now the safest and most efficient to mine.
 * Even though these areas are called dungeons, and are supposed to be secret (they're not shown on the World Map), the dungeon holding the maple and willow trees is on the world map (even though the You are Here icon isn't displayed) and it isn't underground.
 * The dungeons are not safe in PvP worlds. You can die and lose your items, but higher level dungeons are great for EP'ing. An emergency teleport is handy though.
 * Although there are 5 free-to-play dungeons, the RuneScape news said that there were only 4.
 * The vine animation is played on your way in a resource dungeon but not on the way out.
 * If you are standing to the side of the dungeon instead of directly in front of it, the vine animation may not play.
 * The Chaos Druids in the Dungeoneering Level 10 Edgeville Dungeon are not aggressive, all others are.
