Have you played enough modded Minecraft that you've gotten used to the idea of a builder's wand? This addition has you covered! If you've never used a builder's wand before, what this addition does is it gives you the ability to craft a special wand that, when held, will let you click on a block face (of up to a 16 block radius of connected same-blocks) and extend it by one block per click. For example, if you have a circle of cobblestone that you want to turn into a tunnel, you can just click on one of the cobblestones to extend it, so long as you have the blocks in your inventory to do so.

Note: For the best experience, you want to make sure you have our resource pack enabled and are using the same Minecraft version as the server so you can view the custom item that the builder's wand uses.
