Pokemon GO Upgrade Items and Components
An upgrade item is an item that can make certain Pokemon develop. The upgrade can be obtained by spinning a PokeStop photo disc. It's sometimes given as a prize in Pokemon GO events.
The Upgrade can also be placed in armor, weapons trinkets, and gathering tools to boost their level of use. The upgrade costs Flightstones or crests, based on the kind of item.
Upgrade components
Upgrade components can be inserted into weapons, armors, trinkets and gathering tools to add attributes bonuses or other effects while the equipment being used. Upgrade components are only available on equipment with an upgrade slot available. Most upgrade components also require that the item being upgraded is above a specific level. Some upgrade components have special visual effects that are visible when they are used. Upgrade components can be obtained by crafting, purchased from karma sellers or exchanged with other players on the Trading Post or used to repair equipment, or acquired as rewards in game.
There are different upgrade components, each of which comes with various bonuses. Universal upgrades, such as gems and inscriptions, can be used in any type of equipment, and offer lower bonuses than other kinds of upgrade components. Infusions are utilized in non-amulet ascended equipment as well as legendary equipment, while enhancements are utilized for certain ascended back items. Most upgrade components can be replaced if they are inserted into an item, but doing so will destroy the previous upgrade. Exceptions are glyphs (which can only be used in gathering tools) and enchantments, which can be removed and put back in.
Insignias and enchantments will show their names in the hover display of the item while upgrades that have a suffix or prefix will add their name to the end of the name of the equipment (e.g. for example, a Radiant Insignia on Tyrian Armor would change the name to Radiant Tyrian Armor). The number of upgrade components that have been added to an equipment piece will be displayed in the tooltip for the item.
Glyphs
Glyphs are special characters that can be inserted into an OpenType font to add decorative or functional elements, like ligatures, ornaments, fractions and swashes registered trademark symbols, and ellipses. The Glyphs panel allows you to look up and insert these unique characters as well as standard glyphs such as em dashes, en dashes registered trademark symbols and glyphs that do not appear in other fonts (such as dingbats).
Each Glyph gives a character boost in their primary stats. It also comes with up to four secondary stats that affect the glyph's radius on your Paragon Board. Secondary Stats can be described as a %-increase that is multiplied when other bonuses have been applied, with the exception of Speed Glyphs which directly increase the speed of the hero.

Selecting the Glyphs and then clicking "enchant" will activate them. This will display a new window with the Glyphs you have that can be applied to the selected item. Note that only the right kind of Glyph can be applied to the selected item in that each weapon, jewelry or armor piece may have a different set of available Glyphs.
You can upgrade your Glyphs by working through Tree of Whisper Quests or Nightmare Dungeons. The more difficult the dungeon, the greater the amount of Glyph experience that you will earn. Once a Glyph has reached the level 15, it can be upgraded using the Glyph Upgrade Altar. Upgrading a Glyph increases its radius on the Paragon Board by one node every 15 levels.
Once a Glyph is leveled up to the desired level You can activate it by selecting it, then clicking the "enchant" button. The resulting glyph will offer the stated bonus and also boost all the other nodes in its range on the Paragon Board. It's important to place Glyphs in the best locations to benefit your build, and this is why it's recommended to prioritize Magic Glyphs early on. Rare glyphs, however, could offer double bonuses when certain conditions are satisfied which is why they're worth checking out for.
If you're having trouble finding a specific glyph, click the cycle widget on the Glyphs panel to show the panel in a number of different views. Each of these views displays the Glyphs using a different font. You can reduce the number of glyphs by choosing an option below "Entire Font". For example, punctuation is only displayed in punctuation glyphs. Math Symbols restricts the selection to mathematical symbols.
Rerolling
Rerolling involves creating item upgrades on a different account to increase your chances of getting the character or weapon you'd like. This can be done in order for you to increase your level faster or to get better loot such as an additional weapon for your character. Many players will reroll until they have the characters that they like, regardless of their power. This can be because they like the design or personality.
You must ensure that you make clean changes when you roll back. You should check locally to see if the patch passes the pre-commit test and run a core dev test. Upload the patch with a clear difference to a problem (see What is an interdiff?) ).
Rerolls can take days or even weeks to complete, depending on the luck of the draw. To save time be sure to avoid the enemy camps which are not mandatory during this time. It is also recommended to avoid repeating quests that can be completed later on in the game. This can help you save time and energy.
When rerolling, it is crucial to be aware of the upgrade system. There are numerous ways to enhance your character's appearance as well as power. Upgrades, rerolling characters and upgrading weapons are all options. It is also crucial to know the limitations of the system.
Rerolling isn't an absolute requirement however it can be an effective way to increase the chances of acquiring an item or character. It could be beneficial when you're trying to find the best character or if you're wanting to test different play styles and builds.
Sets
A set is an object collection having 2 common attributes (like the number or eggs in a dozen or the members of a group). Sets can be used to perform operations such as intersection, union, and difference.
If you upgrade a set item, it is a different version of itself that is superior to the previous version. For weapons and armor this means that it gets an increased base defense value as well as an lower strength requirement, and an lower requirement for level.
Upgrades are an excellent method of bringing popular single-set items up to level with their higher-tiered set counterparts. Upgrades such as Guillaume's Face Helm to Elite Spired helmet can increase the defense by 217 to 321 and lower the strength and levels to an achievable range.
It is important to keep in mind that not all items in the set are suitable for upgrading. Certain sets, like the FB Sorc spec's Whistan's Shield or Naj's Puzzler staff are already exceptional and elite in their own right and do not need upgrading. Some items, such as Goldwrap and Whistan's Shield (both BiS) that are used frequently may be benefited by an upgrade to improve their value. It could be worthwhile to upgrade these items.
