How to Upgrade Items in Pokemon GO
The Upgrade is one the most important features in Pokemon GO. It allows trainers to evolve Porygon into Porygon2 and gives them the chance to advance in their Pokedex.

While it is rare, players can find it by spinning a photo disc at a Pokestop, or as a reward at special events. But what does this item actually do?
Components
Upgrade components are objects that can be put into trinkets, weapons or gathering tools to provide an additional bonus or effect while the item is being used. They are an essential component of crafting and can be obtained by salvaging or buying from vendors. You can also find them as drops, either from enemies or item spheres. They can be used to upgrade any weapon or armor with an upgrade slot.
To get the highest amount of progress in the game, it's important to use upgrade components to maximize the amount of experience gained from upgrading gear and weapons. The multiplier of experience of an upgraded item is increased by incorporating organic components, while mechanical components reduce it. The best combination is a high experience-multiplier organic component followed by a low-experience-multiplier mechanical component. This will increase the amount of learning experience you get and make it easier to reach the next level.
It's important to know how the upgrade system functions to maximize the benefits of your upgrades. The system keeps a running total of the item you're upgrading. Each component has an experience multiplier, and once the total is at a certain level the value will be reset to zero.
The amount of experience gained by every upgrade component can be influenced by the item's hidden rank as well as its experience multiplier. The higher-ranked items will be more difficult to upgrade while lower-ranked items are simpler to obtain.
When a new hardware upgrade is installed, it's essential to remove all existing connections and fasteners that hold the old component in place. Save these for later in the parts tray for quick identification and secure storage. Once the new hardware is installed, re-connect any cables or wires and connect the power supply to electrical power. Then, test the computer by switching it on. If everything is connected properly the computer should start normally. This is a crucial step to ensure that the new hardware will function seamlessly with your existing system.
Glyphs
Glyphs can be an excellent tool to improve your equipment however, you must be aware of how to utilize it. Each glyph comes with a range of values that it can enhance a substat by and higher-rank Glyphs have more powerful values. Choose wisely because you can only upgrade Glyphs once. Glyphs can also be used only once, so they disappear when you use them on an object or artifact.
The most effective glyphs are the ones which increase your chances to roll an affix of the desired tier or type. They are typically found on the best weapons, armor, and accessories. They can also be found on the Paragon Board and are usually worth the extra effort, but they may be difficult to find.
You can find Glyphs in the Black Lion Chests or purchase them at the Trading Post. Some glyphs are only available for one-time use some are not, while others are permanently. They are a great choice for items that have to be re-rolled frequently. The Glyph of Hope, for instance, lets you increase the probability of acquiring a specific affix when you are enchanting items.
Some glyphs are also used to change existing affixes. This is most common on gloves, boots and belts, which are can accommodate four different affixes. The Glyph of Insight for example, turns a prefix in an experimental affix. This is a useful tool if you are looking for an excellent affix for the specified slot or want to maximize damage output.
Once you've reached level 50, the nature of the game shifts dramatically. You'll no longer be able to rely on the campaign. Instead, you'll have to navigate the Paragon Board, Nightmare Dungeons and grinds that are new to optimize your build.
The best glyphs are the ones that are compatible with your character's class, such as the Exploit Glyph, which increases the damage dealt to weak enemies. Control Glyph is another good glyph that boosts damage against enemies that are frozen, stunned or slow. Each glyph has a radius and the radius increases as you upgrade the glyph. This makes glyphs an excellent way to upgrade your gear later in the game.
Reroll tokens
A reroll token is an upgrade item that allows players to modify one of the attributes of an item. It is possible to do this within the item window by selecting an item, and then clicking a green button that has circling arrows. The cost of the reroll is determined by the rarity of the item.
Reroll tokens can be found in the Mystery Box, as a rare drop from skulled creatures or purchased from the Trader. They can also be obtained via Event Items and can be obtained from other players. They are used to reroll rings, armors, weapons and other items in increments of 2. Each token rerolls gives players a chance to roll for a new attribute, which can be either higher or lower than the previous one.
The token for rerolling is not only used to reroll upgrade, but can also be recycled to reuse items. Recycling an item can earn players a certain amount points, which will be added to the gauge of level for the item, based on its popularity. This is a good way to get rid of outdated, ineffective equipment that hasn't been upgraded.
The rerolling token may be used to provide the player a new weapon characteristic. These are displayed to the player, who has the option to choose whether or not. The player can offer up to six items at once and the choices increase depending on the rarity of the item and level rises. This option is accessible via the Upgrade tab on the forge.
A reroll token can also be used to roll the set bonus of an item. It is triggered when three or more items from the same set are fitted to the unit. The set bonus is only available to units that belong to the same class. It is not applicable to other classes.
There are also a number of other upgrade items within the game that can be rerolled, for example, the recipe items. These items aren't available in the shops or through rerolls, but are 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 these additional bonuses, but the base stats (including all upgrades), and level will remain the same.
Leveling
In the game, you are able to upgrade your equipment by using item upgrade s. These items can be made by obtaining the ingredients needed from NPCs who are item upgraders in major cities. Once an item is upgraded, it will be given a bonus to its base stats. Certain affixes may also be changed. This can result in a significant boost to the ilvl of an item.
If an item is upgraded it will have an icon of blue in the upper-left corner. The item will also show a number of upgrades below its maximum level. A greater amount of upgrades will raise the item's maximum level. The player can upgrade an item as many times as he wants. This will let them hit breakpoints on gears which will increase the reroll chance of certain affixes.
The feature of upgrading items lets players upgrade the level and quality of helmets, weapons, and armor. The process involves the purchase of items, which are then traded at the upgrader NPC to exchange them for currency. The upgrader will show a preview of the item's new level and will accept Happy Stars or Happy Tickets to complete the upgrade. Materials used to make the upgrade will be lost, but the upgraded item will be able to keep its Item EXP to allow for future upgrades.
Although there isn't a 100% sure way to obtain an upgrade but it does have the lowest chance of being lost when spinning Pokestops and Gyms. Players can use an upgrade to transform the Porygon into an Porygon2 which will eat the item.
