Not a trap but [[Tools|tool]] really, they have many uses nonetheless. For one, if you place a few on top of a mine that you planted yourself, they will almost certainly kill anything that stands upon the mine because of the united explosion. This is even better with big mines. Also, sometime when you throw a backpack full of gunpowder at an enemy, they will pick it up, which makes them easy prey for the wielder of a wand of fireballs. If placed on the ground, a nearby explosion will set them off, causing a chain reaction. This is very useful for clearing out hoards of enemies, and is VERY useful in the Big Room floor in Caves.
===Mirrored ChestsChest===
Hardly a trap at all, there are sometimes [[chests]] placed in the dungeons which contain extremely rare and precious loot (think an amulet of life saving, [[Valpurium]] [[flaming sword]] +3 and a cloak of invisibility in a single chest). You could consider yourself lucky as hell, but these items are nothing but a mirrored copies, placed there to tease you. They will vanish soon, so make out of them as much as you can.
===Trapped Door===
Arguably could be also categorized as a normal trap, trapped door will detonate if you try to open them. The explosion triggered will be exactly the same as of a landmine, so all information on mines applies on the trapped doors as well.
Also of note is a glitch in calculation of the damage done by an explosion: The damage done is decreased the farther you are from the explosion. However, the distance is calculated orthogonally and thus standing diagonally to any door while opening them will decrease the damage done if they are trapped, as the game will think you are two tiles away from the explosion rather than one.
