As you may or may not know, my good computer is busted. So I'm here to recruit people to play the only true multiplayer feature of Runescape. The dungeons!
It's basically a dungeon with a survivor twist. You have to make all your equipment and supplies inside the dungeon using materials you find or trade with the smuggler.
"Dungeoneering features a castle named Daemonheim, which currently contains 35 underground floors, although more will be added in Batch 2, including warped and occult themes. Within the castle, players explore and use all other pre-existing skills to clear each floor, involving finding keys, fighting monsters, and solving puzzles. Unlike other skills which are performed alone, players can cooperate together venturing under the castle in groups of up to five people. Additionally, players may earn a small amount of experience in other skills by accomplishing various tasks.
The skill is trained entirely within Daemonheim, which essentially equates to a separate subsection of Gielinor. No items created or found within Daemonheim can be removed from the dungeon, likewise, no items found or created on Gielinor can be taken into Daemonheim, with the exceptions of the Ring of kinship and the Orb of Oculus only. Training Dungeoneering is heavily dependent on the other skills trained outside of Daemonheim. The items and skilling materials used within Daemonheim are all different and the skill is designed to be group-oriented rather than being individual-oriented, although it is possible and widespread for players to train by themselves.
Players can train Dungeoneering past level 99 all the way to level 120, at which point the player will have over 104 million experience. This new maximum level, which is only applied to Dungeoneering, is called "True Skill Mastery"."
