Dial-a-Damage Lock

A numbered dial is in the middle of the door. It is numbered 0-10.

Magical Trap


When the knob is turned, it decreases the difficulty of opening the door but also increases the damage when the door is opened.

A DC 14 Intelligence (Investigation) check reveals that the knob controls the tension in the mechanisms holding the door closed, and turning it will lessen it, making the door easier to open.

The door requires a DC 20 Strength check to open. Subtract the number on the dial from the DC, so if the dial is set to “5”, then the DC is 15.

However, when the door is opened, it deals force damage. All targets within 30′ of the door take nd6 force damage, where n is the dial setting. There is no saving throw.

A detect magic spell or similar spell detects an aura of evocation on the dial.

A dispel magic cast on the dial removes the force damage effect, but the tension effect is mechanical and remains intact.

The dial can be hacked with a successful DC 18 Dexterity check with thieves’ tools. If successful, the number on the dial is treated as 5 less for purposes of dealing damage.
