The Upgrade Item in Pokemon GO
The upgrade item in Pokemon GO is a special enhancement item that helps certain monsters in the pocket increase their power. It's a crucial step towards mastering the evolution and expanding your Pokedex.
Players can acquire upgrade items by spinning Photo Discs at PokeStops and Gyms for seven days in a row, and also by completing events-specific Field Research tasks. These items aren't common, but they do drop.
It is used to evolve Porygon into Porygon2
In Pokemon Go players can utilize a unique item called the Upgrade to transform certain Pokemon into their more powerful forms. This process is not difficult, but does require a few steps. It provides a fresh dimension to the gameplay.
One of the most unique Pokemon in the Pokemon franchise is Porygon that can be transformed into Porygon2 and then into Porygon-Z. To unlock these changes, you'll need have a few things. These include the Upgrade and Dubious disc. Although these items aren't common, they're not impossible to find in the game.
The Upgrade is a scarce item that can be used to unlock the second stage of evolution for Pokemon Porygon in Pokemon GO. To obtain this item, players need to capture and transfer a Porygon. Each capture and transfer will result in one Candy, so it's best to gather a large amount of the creatures. Trainers can attempt to get this item by spinning PokeStops. They are likely to drop the item, as well as other rewards.
The Dubious Disc, another rare item that is found in Pokemon GO, can be used to improve Porygon's powerful form. To acquire this item, players must to collect 50 pieces of Porygon Candy. This can be achieved by taking a Porygon and transfer them to Professor Willow, or walking with the Pokemon as a companion. Trainers can also spin PokeStops in order to try to hit this item, but it's a bit more difficult.

Transforming item upgrades into a secondary form is an enjoyable process that adds depth to the Pokemon GO experience. It requires a few unique items and in-game currency, however, it's not too difficult to achieve.
Contrary to the majority of Pokemon in the series, Porygon can only be evolved into its final form using an item called the Upgrade. This item is extremely scarce and can only be found by spinning PokeStops, or by working on research Breakthroughs. You can also get the item when you trade an Porygon with the item or if you make use of an item that is a Special Trade item.
It is a tier 4 special drop
Upgrades are items that can be used to enhance equipment by adding new features. Players can find upgrades in the game's inventory, karma merchants, or as rewards from special events. They can be added to weapons, armor, trinkets, and gathering tools. Upgrades can be added to any slot on the unit. However, some upgrades require a product above a certain level to be added. Most upgrade components can be replaced, however, doing so could destroy the previous one. Only a handful of types of upgrade can be salvaged by using salvage kits that are of high quality like the Black Lion Salvage Kit and Ascended Salvage Tool.
Items can be upgraded by combining the upgrade item with the item that it is placed in, or by rerolling it with a reroll token. The rerolled item has the same stats as the original however it also has a new tier and level. Each item has a maximum level of upgrade and a minimum level. The rarity of the item and its level determine the tier. Each tier is broken down into three levels, and each level has a different amount of upgrade costs and bonuses.
Generally, upgrading an item will boost its primary stat by a certain amount, and will also give an additional stat randomly. As an item's tier increases it will cost more to upgrade it will increase. However, there are discounts for certain items, and with each step the amount of upgrades required will decrease.
The upgrade item is obtained by spinning Photo Discs at PokeStops and Gyms but it is unlikely to drop each day. It is also available as an incentive for a seven-day streak of spinning at least one PokeStop or gym Photo Disc every day, or through research tasks that are specific to an event.
