There are many traps located in the dungeon of varying danger. These traps are hidden from sight and are triggered only when your character walks over them. If you have found a trap you can attempt to Disarm it, but failure may mean activating it. Traps can be physical dangers such as pits, or magical runes or inscriptions which will cause an effect when triggered. Your character may be better at disarming one of these types of traps than the other.
All characters have a chance to notice traps when they first come into view (dependent on searching skill). Some players will also get access to magical means of detecting all traps within a certain radius. If you cast one of these spells, there will be a ‘Dtrap’ green label on the bottom of the screen, below the dungeon map.
Some monsters have the ability to create new traps on the level that may be hidden, even if the player is in a detected zone. The detection only finds the traps that exist at the time of detection, it does not inform you of new ones that have since been created.
