Constitution is used in Dungeoneering as in normal combat. It is currently not used in any kind of puzzle doors or rooms directly, however many puzzles deal considerable amount of damage to those failing to solve it, thus high constitution would be essential in completing some dungeons. Several puzzles would deal over 3000 life points of damage at once to players, such as failing to open skill doors or getting caught by an orb in the Lodestone puzzle room. Higher constitution levels could be also considered an advantage in the Portals puzzle room ecountered in the warped theme floors, in which moderate damage is dealt continuously until the centre of the portal maze is reached.
