You can close door on yourself, other monster, or any item. If you close door on other monster, you won't be able to attack him untill he moves from there, or you open the door. If you close door on yourself, monsters that cannot open doors, and cannot hit you there(shotgunners, and any monsters with exploding attack) will stay next to you doing nothing.
You close the door.
You wear/wield : a green armor [1/1] (100%)
