Sand and other gravity block duplication (concrete powder, gravel, dragon egg, anvil) has been a staple of Minecraft for many years. However, the Paper developers have patched sand duplication and not provided a configuration. This plugin brings back the dupes.


  • Enable duping for each different block
  • Allow duping in some worlds but not others
  • Enable sand duping on Paper servers
  • 1.13-1.18+ servers. Complete cross-version compatible. No NMS or reflection!
