How to Upgrade Items in Pokemon GO
The Upgrade is among the most valuable items in Pokemon GO. It allows trainers the chance to transform Porygon2 into Porygon, and to advance in their Pokedex.
This item is rare but can be found by spinning a Photo Disc at a Pokestop or as a prize during special events. But what exactly does this item actually do?

Components
Upgrade components can be added to weapons, trinkets or gathering tools in order to give them an attribute bonus. They are a crucial component in the crafting process. They are obtainable by salvaging or buying from vendors. They can also be found as drops in the game dropped by enemies, or gathered from spheres of items. They can be used to upgrade any weapon or armor with an upgrade slot.
Using upgrade components to maximize the experience gained from upgrading weapons and gear is key to achieving the highest level of progress in the game. The addition of organic components to an upgraded item will increase the item's experience multiplier, while mechanical components will reduce it. The best combination is a high experience-multiplier organic component followed by a low-experience-multiplier mechanical component. This will maximize the learning experience you get and make it easier to reach the next level.
The upgrade system is a bit complicated and it's essential to know how it works to maximize the benefits of your upgrades. The system keeps a running total of experience for the item you're upgrading. Each component has either a positive or negative multiplier, and once the total is at a certain level the value will be reset to zero.
In addition the amount of time gained from every upgrade component is affected by the hidden rank of the item being upgraded as well as its multiplier of experience. The higher-ranked items will be more difficult to upgrade while those with lower ranks are less difficult to acquire.
If a new version of the hardware is installed, it's important to remove all existing connections and fasteners that hold the old component in place. Keep them in a parts tray to facilitate identification and storage. Once the new hardware is installed, reconnect any cables or wires and connect the power supply to the electrical power. Test the computer by turning on. If everything is connected properly the computer should start up normally. This is an important step to ensure that the new hardware is compatible with your existing systems and will work seamlessly.
Glyphs
Glyphs are a great tool to make your gear better, but you need to know how to use them correctly. Each glyph can be used to enhance a substat, and the higher the rank of a Glyph, the more powerful it will be. You can only upgrade a glyph only once, so make sure you make sure you choose wisely. Glyphs are only available once, which means they will disappear after you've used them on an object or artifact.
The most effective symbols are those that increase the likelihood of rolling an affix that matches the desired level. They are typically found on the most expensive weapons, armor and other accessories. They are also available on the Paragon Board. They are worth the extra effort but aren't always easy to locate.
Glyphs are available in the Black Lion Chests, or purchased at the Trading Post. item upgrading are available for use only once some are not, while others are permanently. These are great for items that need to be re-rolled often. The Glyph of Hope, for example, allows you to increase the chance of acquiring a particular affix when enchanting items.
Certain glyphs may be used to alter existing affixes. This is common on gloves and boots. Each can host four different affixes. The Glyph of Insight, for example, transforms a prefix into an experimental affix. This is a helpful tool if you want a high-quality affix in the specified slot or want to maximize damage output.
Once you reach level 50, the nature of the game dramatically changes. Instead of being a reliance on the campaign, you'll need to navigate the complex Paragon Board, Nightmare Dungeons and new grinds in order to ensure that your build is as perfect as you can get it.
The best glyphs will be ones that correspond to your character's specialization, for example the Exploit Glyph, which increases damage against vulnerable enemies. Other excellent glyphs include Control Glyph, which boosts damage to enemies that are stunned, frozen, or slow. Each symbol has a radius and the radius grows as you upgrade it. This makes glyphs the best way to improve your gear in the final game.
Reroll tokens
Reroll tokens are an upgrade item that lets players alter one of the attributes on an item. This can be done within the item window by selecting an item, then pressing an green button that has circling arrows. The cost of rerolling is contingent upon the rarity of the item.
Reroll tokens are available in the Mystery Box or as rare drops from skulled monsters. They can also be purchased from the Trader. They are also obtained through Events Items and can be obtained from other players. They can be used to reroll weapons, rings, and armors in increments of two. Each token that is rerollable gives players the chance to roll for a new attribute, that could be higher or lower than the previous one.
The token for rerolling is not only used to upgrade the reroll, but can also be used to recycle items. The rarity of the item determines the number of points players will receive for recycling it. This is a great method to get rid old obsolete equipment that hasn't been upgraded.
The rerolling token can be used to provide the player a new weapon characteristic. They are then shown to the player, who can decide whether or not. The player can offer a total of six items at a time and the variety of choices increases as the item's level and rarity increase. This option can be accessed through the Upgrade tab on the forge.
Reroll tokens can also be used to reroll an item's set bonus, which is applied when three or more items from the same set are installed on an item. The set bonus only applies to units that are part of the same class and cannot be applied to units belonging to different classes.
There are a variety of other upgrades in the game that can be rerolled, such as the recipes. They are not available through the shop or reroll, but instead transferred to the Non-droppable Pool when players select a Food Card that requires new ingredients or Equipment. The reroll token can be used to reroll the extra bonuses associated with these items however, the basic stats and levels (including any upgrades) will remain unchanged.
Leveling
In the game, you are able to upgrade your equipment using item upgrades. These items can be made by obtaining the ingredients needed from NPCs who are item upgraders in major cities. After an item has been upgraded, it will receive an increase in its base stats. Certain affixes may also be rerolled. This can result in significant increases to the value of an item's ilvl.
In the top-left corner an icon in blue will appear when an item has been upgraded. It will also display an amount of upgrades below its maximum level. A greater number of upgrades will boost the item's maximum level. The player can upgrade an item as many times as they want. This will let them reach gear breakpoints that increases the chance of rerolling certain affixes.
The ability to upgrade items gives players the ability to upgrade the level of their weapons as well as helms and armor. This process costs items, which can be exchanged at the upgrader NPC to exchange them for currency. The upgrader will show an image of the item at its new level, and will accept either Happy Stars or Happy Tickets to complete the upgrade. Materials used to make the upgrade will be destroyed, however the upgraded item will retain its Item EXP to allow for future upgrades.
Although there isn't a certain method of obtaining an Upgrade, it does have very little chance of falling when spinning Pokestops or Gyms. Players can use an Upgrade to evolve into a Porygon into the form of a Porygon2, who will consume the item.
The Upgrade is a special evolution item from the Pokemon series, first introduced in Generation II. It's a transparent gadget packed with a variety of information, manufactured by Silph Co. It is a tool to create specific Pokemon species and can be activated by trading a Link Cable. It is a very rare item that has an 1% drop rate per spin at Pokestops and Gyms. It can also be obtained by taking part in the Upgrade Station event.
