# Upgrading Warriors **Upgrading a warrior can potentially be the difference between an invisible farm to a losing farm.** The [upgrade NFTs](/chapter-1-farm-wars-the-game-structure/the-farm-wars-nfts.md) will become available to a player as the farm advances in the levels. As we promised Farm Wars is a game with a twist so the upgraded warriors will **change every quarter and be removed from circulation as the quarter ends**. For example upgraded warrior a player will have the chance to mint in February will no longer exist to anyone in May, and a newly upgraded warrior will be available instead. --- # 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.
