Colony Protection System
The protection turns all explosions off (by default), so creepers, TNT, and any modded blocks won’t destroy your colony. By default, only the colony owner can break or place blocks within a colony, but you can add other players in the permissions section of the Town Hall GUI.
It covers from bedrock to the sky limit, so you don’t have to worry about griefing under or above your colony.
Note: The protection system depends on the border system. Only areas that are within the colony’s border will be protected. See the Colony Border System page for more information.
