On Cavetale, you can claim land as your own to protect against malicious players trying to break your projects or steal from you. Claimed land allows the owner to build in peace without worry of other players building on it. Claim owners also have the ability to allow who gets to build on their land. A claim reaches from the build height all the way down to bedrock.
All claim-related commands can be found by typing /Claim.
After finding a location in the home world to build (/wild helps with this), stand in the center of the area you’d like to claim and type /claim new. Your claim will have the dimensions of 32 x 32 by default, and can be expanded later by purchasing additional claim blocks. Allow your friends to build in your claim with /claim add <player>.
The number of claim blocks you have determines how large your claim can be. In order to acquire more claim blocks, you must purchase them via /claim buy [blocks]. Claim blocks are sold at a rate of 10 blocks per coin.
Eventually, you may wish to divide your claim into smaller sections with unique permissions, such as for the purpose of creating plots in a town. To do so, see /subclaim for a list of relevant commands.
The owner of the primary claim will also have ownership over any subclaims within its borders, but other players trusted in the primary claim will not automatically have access to subclaims. Subclaim permissions are unique and must be configured independently of the parent claim.
