The Miner's Traps

To be honest, making traps in Minecraft requires vast knowledge of game items, creativity, and player behavior. It is true that trap blueprints will allow you to create traps instantly. However, it will limit you to those traps you see alone. And unfortunately, using the same trap all over again is not fun - not to mention that your victims will become used to them and become capable of detecting and disarming them.
