Upgrading Weapons

Chapter 5 : Sub : Upgrading the Farm
Upgrading a weapon is a big deal! Weapons will turn your defense and attack into a much stronger army.
These upgrade NFTs will be available when the farm advances in levels and are only available for players at a specific time for a particular duration. If a player decides not to use the available mint upgrade, the upgrade will become unavailable to the player after some time.
All upgrade NFTs can be listed and sold on the secondary market.
