It is a tier 4 special drop
An upgrade item is a product used to improve equipment by adding additional attribute bonuses. The players can find upgrades in the game's inventory, karma merchants, or as rewards from special events. They can be added to armor, weapons trinkets, trinkets, or gathering tools. An upgrade can be inserted into any slot of an equipped unit. However certain upgrades require an item above certain levels to be added. The majority of upgrade components can be altered however the original component will be destroyed. Only a handful of upgrade types can be salvaged by using top-tier salvage tools, for instance Black Lion Salvage Kit or Ascended Salvage Tool.
Upgrades can be achieved by by combining an upgrade item with the item it is placed in, or by rerolling the item with the token that rerolls. The new item will have the same extra stats as the original, but it will also have a different level and tier. Each item has a maximum upgrade level and a minimum item level. The rarity of the item and its level determine the level. Each level is divided into three levels. Each level comes with its own upgrade costs and bonuses.
Generally upgrading an item will increase its main stat by a certain amount, and also provide an additional stat randomly. The cost to upgrade an item increases as its tier increases however, there are discounts available for certain items and the amount of upgrades required decreases with each step.
The upgrade item can be obtained by spinning Photo discs at PokeStops and Gyms, though it is very unlikely to be dropped every day. It is also available as an incentive for a seven-day streak of spinning at minimum one PokeStop or gym Photo Disc per day, and through event-specific Research Tasks.
