Staff of Duplication

The Staff of Duplication is a tool from the Witchery mod. It was a development tool that Emoniph left in the mod. It is used to create schematics, or duplicate regions of the world. It can only be obtained by using the /give command, creative mode, or NEI's Cheat Mode option.

Usage
Right clicking on a point will begin the region selection, which can be completed by right clicking another point. All of the blocks in a cube between them are remembered. Then, it can be right clicked in another point, and the region will be duplicated, or paste, onto that point, based on the first block that was clicked. Clicking in the same place will cause the region to rotate. Sneak+right clicking in the air will cause the saved pattern to be cleared, allowing it to be used again.
