Dungeon

Dungeons are described as chained instances. Dungeons are reset by exiting and re-entering them, while a party remains within a dungeon, there is some degree of persistence between its zones. Though dungeons were not added before Eye of the North, there are some areas (mostly Elite Missions) in previous campaigns that behave in similar ways. Completing dungeons in Eye of the North for the first time will result in loot, reputation points and progress in the Master of the North title track. Dungeons can be redone as many times as you wish for loot and reputation points. Each dungeon in Eye of the North has a reward chest. Opening the reward chests in dungeons does not count towards the Treasure Hunter title. In every dungeon, killing 25 enemies gives a 7% Morale Boost to the entire party. A completed dungeon is added to your Master Dungeon Guide.

Trivia

 * Several of the Eye of the North Dungeons have some elements resembling the Legend of Zelda series dungeons or underworlds. Examples include (but not limited to): finding secret passages, blowing up walls with bombs (or in this case, a Powder Keg), various traps, the Oozes (like gels), the bats (blood drinkers), using keys to open locked doors (including boss keys), the treasure chests (including the big ones), finding the maps with the skull marked as the boss, and using the skill Light of Deldrimor similarly to playing the ocarina/whistle to reveal secrets and weaken some enemies.
