Claims And Raids adds only one block to the game: the Chunk Cupboard.

The Chunk Cupboard block(which is the icon of the project) works similarly to Rust's tool cupboard. Anyone who isn't authorized in the chunk cupboard can't place or break blocks in the chunks it claims, and optionally can't interact with blocks too. All these restrictions are configurable.

For the chunks to remain claimed, the Chunk Cupboard will have an upkeep cost. To cover this cost, items must be placed inside the Chunk Cupboard(it's like a double chest). Which items, how much cost each item provides, and how much cost each chunk provides are all configurable.

For a player to allow themselves in the Chunk Cupboard, all they gotta do is right click it! This makes it so that protecting the Chunk Cupboard is the most important part of a base.

Chunk cupboard claims cannot overlap, the mod won't let you place one that influences the area of another one, even inactive ones.

This is has compatibility with Sable. A Chunk Cupboard affects an entire sublevel.
