Upgrading Warriors

Chapter 5 : Sub : Upgrading the Farm
Upgrading a warrior can potentially be the difference between an invisible farm to a losing farm.
The upgrade NFTs 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.
