Upgrades are items that can be used to upgrade equipment, adding new features. Upgrades are available in the game's Inventory, from karma merchants, or as rewards for special events. They can be added to weapons, armor trinkets, trinkets, or gathering tools. An upgrade can be put into any slot on an equipped device. However certain upgrades require a product above certain levels to be added. The majority of upgrade components can be modified however the original component will be destroyed. Only a few types of upgrades can be salvaged by using top-tier salvage tools, like the Black Lion Salvage Kit or Ascended Salvage Tool.
Upgrades can be achieved by by combining an upgrade item with the item it's placed in, or by rerolling the item using the rerolling token. The rerolled item will have the exact stats as the original, but will also have a different level and tier. Every item has an upgrade level maximum and level minimum. The item's rarity and level determine the tier. Each tier is broken up into three levels, and each level comes with a distinct cost for upgrades and bonuses.
In general upgrading an item can increase its main stat by a certain amount, and gives you a random extra stat. As an item's tier increases and the cost of upgrading it will rise. However there are discounts on certain items and with each upgrade, the number of upgrades needed will decrease.

The upgrade item is obtainable by spinning Photo Discs in PokeStops or Gyms. However it has a low chance of dropping every day. It can be earned by spinning at least one PokeStop Photo Disc or gym Photo Disc every day for a 7-day streak as well as by completing Research Tasks and event-specific tasks.
