Upgrades are items that can be used to improve equipment by adding new attributes. Upgrades are available in the game's Inventory, from karma merchants, or as rewards for events. They can be added to armor, weapons, trinkets, and gathering tools. An upgrade can be put in any slot on an equipped device. However, some upgrades require an item that is above an aforementioned level to be added. Most upgrade components can be replaced, however, doing so could destroy the previous one. Only a handful of upgrade types can be salvaged by using top-tier salvage tools, such as Black Lion Salvage Kit or Ascended Salvage Tool.
Upgrades can be made by either combining an upgrade item with the item it is placed in or by rerolling the item with an rerolling token. The new item has the same additional stats however it also has a new level and tier. Each item has a maximum level of upgrade and a minimum level. The levels of upgrade are determined by the item's tier, which is determined by its rarity as well as its level. Each tier is divided into three levels, and each level has its own amount of upgrade costs and bonuses.
Generally upgrading an item will increase its primary stat by a fixed amount, and also provide a random extra stat. As an item's tier increases, the cost to upgrade it will rise. However there are discounts available for specific items and with each upgrade, the number of upgrades needed will decrease.
The upgrade item is obtainable by spinning Photo Discs at PokeStops or Gyms. However it has a low chance of dropping each day. It can also be obtained as an incentive for a seven-day streak of spinning at least one PokeStop or gym Photo Disc each day, and through specific research tasks for events.
