# Castles ### What is a Castle? * **A Castle (CASTLE) is a DAO and the Knights from it are the DAO's members.** * **Castles can be used to mint new Knights with a discount.** The discount increases based on the amount of Knights it has minted. The more Knights a Castle mints, the better the deal gets to mint a new Knight. * **Castles can level up.** High tier Castles can even issue custom tokens. ERC20 and/or ERC721. The highest tier "Citadel" has an amount cap of 7; the 2nd highest tier "Castle" has an amount cap of 21. * **Castles can tax its Knights.** A part of that Knight's earnings go to the Castle. * **Knights from a Castle can have exclusive skins.** Castle art design is customized. * **The CASTLE Smart Contract is upgradable.** They will have more features as the game developments. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
