Sawblade Stairs

A circular staircase leads upwards.

Mechanical Trap


The staircase is one huge saw, with each stair a blade.

A DC 12 Wisdom (Perception) check detects that the front edge of each stair has very small teeth.

A DC 14 Wisdom (Perception) check reveals that 10 of the middle stairs have small springs underneath it where it attaches to the post.

When a stair more than halfway up is stepped on, the entirie staircase rotates. Each target on the stairs must make a DC 16 Dexterity saving throw. On a success, the target may jump off, taking appropriate falling damage. On a failure, they take the falling damage as well as an additional 8d6 slashing and bludgeoning damage.

The saw can be disabled by disabling the spring mechanism. This requires a DC 14 Dexterity check with thieves’ tools. Failure sets off the trap.
