BuyClaimChunks is a lightweight Forge mod that adds a convenient way for players to purchase extra claim chunks in FTB Chunks using items as currency. Perfect for servers looking to give players a simple and configurable way to expand their territory without granting admin privileges.

Features:

/buyclaim [amount] command – Buy 1 or multiple claim chunks at once.
Item-based currency – Require any item (vanilla or modded) to purchase claim chunks. Configurable in config/buyclaimchunks-common.toml.
default values: itemRequired = "minecraft:diamond" amountRequired = 1 maxExtraClaims = 100
Configurable amounts – Set the number of items required per claim chunk and the maximum number of extra claim chunks a player can buy.
Max limit protection – Players cannot exceed the configured maximum, and purchases that would go over the limit are blocked.
Supports modded items – Any item registered in Forge can be used as currency.

Requirements:

FTB Chunks
Forge for Minecraft 1.20.1
