Puzzles: Metal Doors

Dungeon designers are not stupid you know.

We add doors to our dungeons. Thick metal doors with complicated puzzle locks to keep out nosy and thieving adventurers. Because nothing says 'keep out!' quite like 1.000 pounds of solid iron.

Puzzles: Metal Doors comes with 15 premade puzzles you can drop into any campaign at a moment's notice. Whenever you decide you want to add a little variety to your dungeon simply pick a puzzle door and show it to your players. They need to collect the metal key pieces and solve the puzzle to open the door.
