What Are Item Upgrades in Genshin Impact? Item upgrades can be added to weapons, armors, trinkets, and gathering tools. They add additional stats, or additional effects. These upgrades can be bought from vendors, traded between players or rewarded as rewards. The process of upgrading equipment is generally a good thing, especially rare and exclusive gear. It is however possible to over-upgrade equipment especially if they are equipped with the highest base requirements. Rerolling Genshin Impact offers a few different ways to upgrade your gear.
