Puncture Knob


 

The den is accessed by a large oak door. It has a single brass doorknob with a push-button in the middle.

Mechanical Trap

This trap has a serrated blade hidden behind the button.

The blade is 1 inch long and mounted on a spring. It extends out 3 inches when the button is pressed.

The edge of the knife can be see protruding through a small slit in the button with a DC 10 Wisdom (Perception) check, after which the knob may be opened and the spring mechanism disabled with a successful DC 15 Dexterity check using thieves’ tools. If thieves’ tools are not used, the Dexterity check to disable has disadvantage.

When the trap is triggered, the creature pushing the button must make a DC 12 Dexterity Save, or take 2 slashing damage. In addition, until magical healing is used or a long rest is taken, the creature is at Disadvantage for any Dexterity based checks that use the hands.
