Adom TrapRoom

This room doesn't look safe...

Traps are a constant risk in ADOM. They have a variety of harmful effects that can damage the player and his equipment, or even alert every monster on the level to the players presence.


When the player or a monster walks onto a square containing an undiscovered trap, it will be set off and either the player will dodge it, or will suffer some form of damage or hindrance. The exact effects of each trap can be found in the trap types section.

Once discovered, a trap will be shown on the map and will become much easier to avoid in future. Note that it is possible to deliberately set off a trap the player is standing on by pressing Ctrl-T. This is very useful with teleportation traps once the player has some form of Teleport control.

The player may create traps using a wand of trap creation. A pit trap can be created by applying a pick axe or casting a digging spell and pressing '5' or '.'. A pit can be covered using a blanket; although in versions of ADOM prior to 1.2.0, this would actually transform the pit into a different type of trap depending on the trap table. The fixing of the trap transforming bug during 1.2.0 development also resulted in the 'trap table' system being removed.[1]

PCs with highly trained Alertness will sometimes discover a trap without activating it. PCs with the Detect traps skill can use it to find traps, although it must be employed actively and thus is generally impractical outside of known, heavily-trapped areas.

Trap typesEdit

There are 12 distinct types of trap in ADOM. See the picture on the top right for an example room of traps.

Trap number Trap name Trap symbol Trap description
1 Light trap Yellow Will blind the player when activated.
2 Corruption trap Purple Corrupts the player when activated. Monsters exposed repeatedly will eventually transform into chaos creatures — some turn into writhing masses of primal chaos, others into chaotic equivalents of their former selves (e.g. rats turn into chaos rats).
3 Stone block trap Gray A stone block lands on the players head, dealing damage. Chance of a stack of rocks being created. Disappears once triggered.
4 Alarm trap Orange Makes every monster on the level hostile towards the PC. If an enemy monster triggers it, the other monsters will attack it too.
5 Arrow trap Orange An arrow hits the player, dealing damage. Chance of an arrow being created. Will eventually run out of arrows and disappear.
6 Acid trap Green Damages the player and damages his equipment. Eventually runs out and disappears.
7 Viper pit Cyan/brown A number of pit vipers are created, and the player falls in a pit. When unopened, this trap is cyan, when the pit has been revealed it becomes brown.
8 Spear trap Brown A spear hits the player, dealing damage. Large chance of a spear being created. Will eventually run out of spears and disappear.
9 Teleportation trap Light green Teleports the player to a random spot on the level, unless the player has Teleport control.
9 Ceiling trap (occurs in lieu of teleportation trap when level forbids teleporting ) Light gray Part of the ceiling collapses, dealing significant damage to PC and their equipment. Item destruction affects the same type of items as a collapsing door, except it seems to carry a greater chance of destruction.
10 Water trap Blue Drenches the player in water, damaging them. Also can destroy or rust equipment and inventory items. Does not run out.
11 Fireball trap Red Creates a fireball, damaging the player and any other nearby monsters. Also causes equipment damage. Limited number of activations before disappearing - 1d10 or less (needs testing).
12 Empty pit trap Cyan/Brown The player falls into a pit, and takes 3-18 damage. When unopened, this trap is cyan, when the pit has been revealed it becomes brown.Brown pit can be covered with blankets and disarmed after.
