Trap

A trap is a terrain feature or feature of an item, such as a door or a chest, that is potentially dangerous or inconvenient to the player. Typically, such traps can be disarmed either through magic or through some mundane skill.

Common trap types:

• pit: possibly modified with spikes or poisoned spikes
• trap door: like a pit, but deep enough to deposit the character on the next level down
• fire: does fire damage
• acid: does acid damage
• missiles: arrows, darts, crossbow bolts, spear, and axes are among the items that may be flung
• explosion: exploding doors in ADOM are a particular treat
• polymorph: perhaps the most notorious of all trap types, it can transform player or monster into a different species
