Block Zapper

Block Zapper is an item that can be purchased via Elizabeth's Bits Shop for. It can be used on Private Islands to zap connected blocks, placing them in its user's inventory.

Usage
When a block on the user's Private Island is right-clicked, the Block Zapper will remove up to 164 connected blocks of the same type from the world and place it in the user's inventory. After zapping, a chat message will inform the user of how many blocks were zapped. Next to it, an Undo button allows the player to undo the previous zap.

The Block Zapper has several limitations:


 * It cannot zap tile entities such as Chests and Crafting Tables.
 * It cannot zap crops or blocks under crops.
 * It cannot zap Prismarine type blocks.
 * This may be because of issues related to Mithril.
 * It can only zap blocks the player has placed.
 * Blocks placed by Minions cannot be zapped.
 * Blocks generated naturally (such as Cobblestone from Lava and Water) cannot be zapped.


 * After 20 uses, it will become fatigued and unable to be used for 7 minutes.
 * It used to be possible to circumvent this by leaving your Private Island and then returning.
 * It will destroy blocks in a straight line, then loop back in a snake-like pattern until the 164 block limit is reached or all connected blocks are destroyed.
 * This is useful for building farms; by building a square of dirt 164 blocks wide (ideally using the Builder's Wand), then using the Block Zapper, you can create perfect water trenches without the need to dig blocks manually.

Trivia

 * When it first came out, the block zapper could be abused to farm crops insanely fast. This has since been patched.
 * Using a Block Zapper on upper-half Red Sandstone Slabs will produce a Null item.
 * This has not been patched as of the May 21st update to Block Zapper behavior.
