Folding Ladder

A ladder has been left leaning up against the stone wall.

Mechanical Trap


The pins in the ladder have been removed, causing it to collapse if weight is put on it. Additionally, the pin holes are filled with a contact explosive that go off either if the pins are put back in or the ladder collapses.

A DC 12 Wisdom (Perception) check detects the missing pins. 

A DC 14 Intelligence (Investigation) check reveals the black substance inside the pinholes as a contact explosive.

If the pins are not re-inserted, once a target climbs 10 feet up the ladder it collapses. The target takes 1d6 falling damage, and must make a DC 12 Dexterity saving throw. On a failure, they take an additoinal 1d6 bludgeoning damage from the ladder. The ladder also explodes as below.

If the pins are re-inserted, the ladder explodes loudly. All targets within 15′ of the ladder take 1d6 piercing and 1d6 fire damage, with a DC 12 Dexterity saving throw halving the damage.

The explosive can be cleaned out with with a successful DC 14 Dexterity check with thieves’ tools. Failure causes an explosion.

The explosive can also be neutralized. With a successful DC 14 Intelligence (Investigation) check, the target can make an alcohol compound that neutralizes the explosive.
