Grater Doors


 

A wide doorway opens to the next room. It appears that there are two separate pocket doors that close together.

Mechanical Trap

This trap uses a pressure plate to trigger two spring loaded doors on each side to quickly close. The pressure plate runs the entire width of the door frame, and is as deep as the door frame. The inside of each door contains a metal grating similar to a cheese grater.

The pressure plate can be spotted with a a successful DC 12 Wisdom check.  (Perception) It can be wedged open with a DC 14 Dexterity check with thieves’ tools. It will remain disabled for 1d4+1 rounds.  If no tools are used, the check has disadvantage. The plate can be disabled permanently with a DC 17 Dexterity check with thieves’ tools, and as before, the check has disadvantage without tools. A DC 5 Strength (Athletics) check will allow a creature to safely jump over the pressure plate.

If the sides of the door frame are inspected, the grating can be made out with a DC 13 Wisdom (Perception) check.

When the pressure plate is stepped upon, the doors quickly close. Those in the doorway must make a DC 14 Dexterity saving throw or be caught between the two doors. Those caught take 3d6 piercing and slashing damage. They are also restrained, and must make a DC 12 Strength (Athletics) check as a standard action to free themselves.
