Falling Floor Trap
You can make anything you want bottom of hole.
Falling floor trap. First and probably the simplest set up a room that is 2 wide with a trapped chest at the end a trapped chest will give off a redstone output when opened so hook it up to a redstone torch to invert the sig. The trip wire is 3 inches off the ground and stretches between two columns or trees. This trap is best placed in a narrow hallway. Place something of value or apparent value at the end of the hallway.
Whoever press that button floor will open up and they will fell into trap. When the party gets halfway down the hallway the floor tilts downward on one end and grease begins covering the floor. If the trap is for a specific victim accidentally on purpose give them some info. 0 comment comment add a comment.
Once the trap is triggered the floor of the area is filled with rubble and becomes difficult terrain. If you try to make the trap tempting it ll be more likely for it to work. Resulting in the target falling to the ground. A false floor trap is a variation of a pitfall trap.
Falling net mechanical trap this trap uses a trip wire to release a net suspended from the ceiling. Any nosy neighbours will fall to their doom. I opted for the latter. The net is hidden by cobwebs or foliage.
The floor of a small medium room is covered in identical stone tiles. There are a couple ways you can do this. Cover it with a trap door and then put a button on the wall next to it. And if they do we can now turn the tables on them by laying a trap.
It works by creating a concealed safe route through the pitfall which is usually very big to allow authorized players to pass while catching unauthorized players or mobs and killing them. Just build a hole in the floor next to a wall in your house. This trap can even be effective. Now if you press the button the trap door will open.
A good trigger for this trap would be a pressure plate or tripwire.
