Upgrades are items that can be used to improve equipment, adding new features. Upgrades are available in the inventory of the game, from karma sellers, or as rewards for special events. They can be added to weapons, armor trinkets, trinkets, or gathering tools. An upgrade can be inserted into any slot on an equipped device. Certain upgrades require that an item with an upper level be added. The majority of upgrade components can be replaced, however, doing so could destroy the previous one. Only a handful of types of upgrade are salvageable by using salvage kits that are of high quality such as the Black Lion Salvage Kit and Ascended Salvage Tool.
Items can be upgraded by combining an upgrade item with the item that it is placed in, or rerolling it with a reroll token. The rerolled item will have the same additional stats, but also a new tier and level. Each item has a maximum level of upgrade and a minimum level. The levels of upgrade are determined by the item's level, which is determined by its rarity as well as its level. Each tier is divided into three levels, and each level has its own cost for upgrades and bonuses.
In general upgrading an item can increase its main stat by a specific amount and offers a random additional stat. As the tier of an item increases it will cost more to upgrade it will increase. However there are discounts on specific items and with each step, the amount of upgrades required will decrease.

It can also be obtained as an incentive for a seven-day streak of spinning at minimum one PokeStop or gym Photo Disc per day, and through research tasks that are specific to an event.
