Spike traps are always fun, whether the players know they are there or not.
This particular type is used in corridors. I either lay it down as a visible challenge or swap out another corridor piece with this once the players spring the trap.
- Start by gluing floor tiles to your foam base. Do not glue the the middle floor tiles however. I still place them on the board when building to ensure the shape and size is correct.
- Glue your walls in place. Remove the unglued floor pieces.
TIP: Check out the rules of the system you are playing and ensure your pits are too far for a normal character to jump over.
