Cannon Trap

A paper screen depicting a nautical scene (instead of a painting) conceals a Large cannon.

Hidden behind the painting is an alcove containing a cannon (and a 50 percent chance of a Minor Treasure). A floor-level tripwire stretches from the wall below the painting to the opposite wall. A creature that walks across the floor trips the wire, triggering a Critical Failure.

Exploration. A distant examination of the painting reveals that it is riddled with punctures. A creature that makes an up-close Investigation check automatically discovers the alcove behind the painting but may trigger the trap. A Perception check or an examination of the floor reveals a taut wire strung across the floor.

Tripwire. Sweeping the floor with a pole or other object triggers the trap harmlessly. A creature aware of the tripwire may simply step over it.

Possible Solutions
  • A creature aware of the tripwire can make a thieves’ tools check to disarm it.

Potential Outcomes

Failure or Critical Failure. The cannon fires shrapnel in a 120-foot cone. Each creature in the area makes a Dexterity saving throw , taking 44 (8d10) bludgeoning damage and 22 (4d10) slashing damage on a failure or half damage on a success. Objects take this damage as well. Once fired, the cannon can’t fire again until the trap is reset.

Success or Critical Success. The trap is disabled.
