To build a standard version of this trap, you will need the following items: 4–8 (depending on the scale). Redstone Dust: 10–15 pieces. Redstone Torches: 2 (for signal inversion).
Use a ceiling-mounted piston to push a block down onto the target's head, dealing consistent damage over time.
When the plate is pressed, the torch turns off, causing the pistons to snap shut.
Smart players often carry a to negate fall damage or lava, or a Pickaxe to break the pistons. To make your trap more effective, consider lining the trap walls with Obsidian , which cannot be broken quickly, ensuring the trap finishes its job before the target can escape.
