# Utility ### Restore XP When a Knight is below its All-Time-High Level, the player can consume RUBY to restore the Knight's Level back. The player will do so because a higher Level Knight can gain access to more features in the game and earn more RUBY when they win a ranked game. ### Purchase In-Game Items RUBY can be consumed to purchase in-game items, similar to how most mobile games provide in-game purchases. ### Mint In-Game Items into NFTs RUBY can be consumed to mint in-game items in a player's account into NFTs, which can be withdrawn into the player's wallet on the blockchain. ### Stake RUBY to Earn Rewards Holders can stake RUBY into a single staking pool on the blockchain. When RUBY are consumed in the game, 60% of that amount will be distributed to RUBY stakers. ### Participate in Auctions There will be NFT Auctions that will be priced in RUBY. Therefore a player must possess RUBY in order to participate in those Auctions. ### Participate in Royalty Pools For Auctions priced in RUBY, the corresponding Royalty Pool will be priced in RUBY as well. Therefore a player must possess RUBY in order to participate in those Auctions. --- # 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.
