A falling rock trap is a type of trap that appears in Nethack.
Generation
If a trap door would be randomly generated on a level with a non-diggable floor, it is replaced with a falling rock trap.
Description
When triggered, the falling rock trap will either drop a rock that hits whoever triggered it on the head for 2d6 damage and lands on the ground, or disappears with a 1⁄15 chance; if the victim is wearing a metallic helm, the damage is reduced to 2.[1][2]
Removal
One way to remove a falling rock trap is to trigger it repeatedly until it runs out of rocks.
Strategy
Early pet deaths are often due to this type of trap, earning it the nicknames "Puppy Pounder" and "Kitty Killer". The falling rock trap can be used as a source of rocks for cheap ammunition.
One of the early game weaknesses of an elven leather helm is the fact that it does not protect against damage from falling rock traps.
History
The falling rock trap was added in NetHack 3.1.0.
