Path of Exile Item Upgrading
In Path of Exile, item upgrading is one of the best ways to upgrade your gear without relying upon large-ticket drops or trade. This article will help you understand how to upgrade your items.
Upgrading equipment grants an increase to the item's base stats. The bonus increases with upgrade component level and rarity.
Components
Upgrade components are the parts that make your weapons and armor more effective. You can locate them through destroying enemies, buying them from karma vendors, or finding them in items-spheres. They can also be salvaged from equipment that has them or by using an advanced salvage kit like the Black Lion Salvage Kit or Ascended Salvage Tool. Upgrade components aren't destroyed when they are removed from the item.
Upgrade components are primarily used to improve an item however, they can also be used for other reasons. They can be used to increase the level of experience gained from upgrading existing weapons or gear. They can be made for additional bonuses. For example, a crafted glyph will boost the chances of upgrading its target, while the boost upgrade can enhance the defense or attack quality of a weapon or armor.
Selecting an upgrade template from the GUI will allow you to connect it to an item. This will show an upgrade component list that the item can be upgraded to. You can also make use of the workbench to choose an upgrade template. In either instance the item will be upgraded after enough upgrade components are collected.
Each component has a different experience multiplier that affects how much more experience an item will gain when it is upgraded with that component. Organic components, for example have a higher multiplier of experience than mechanical components. Therefore, it is recommended to upgrade with organic components until you reach the experience multiplier for the next rank of the equipment or weapon, and then move to mechanical upgrades.
In addition to the multiplier of experience, each item also has an maximum number of upgrades it can receive. The number of upgrades are determined by its upgradeable rank and the type of upgrade for the upgradeable item. For instance, the highest possible upgrade for a weapon is a weapon of tier 10. The most commonly used upgrade is a gun of tier 6 and an armor upgrade of tier 5.
Sets
A set is a group of items that share a bonus. Each item in the set can be upgraded at least one time, and the upgrade increases the guaranteed bonuses. The first time you upgrade an item, its initial stat will be +1. After subsequent upgrades the stats of the primary one will be increased a bit more (for example, +1 to 12+/13+/14+) Every time you upgrade the item, one of its extra stats will be increased randomly.
Upgrades can also increase the base damage of a weapon. This may be important for certain types of weapons. Weapons cannot be upgraded for an increased maximum defence roll than their base. It's possible to increase the value of certain set and unique items by upgrading them, but they may not always be superior to a high-level Runeword.
If you are upgrading an item with bonuses the item can be rerolled once, and its guarantee will reset to 0. Rerolling will cost the same amount of power dice as bringing an item up, but the new item will have different extra bonuses. Upgrades can be made by visiting the NPC [ArmorBoboko. Boboko in Central Flarine. To upgrade an item you will require the required amount of Minerals and Erons and a power dice of each type. These are available at the crafting table or the Ultra Collector, and can be purchased using Gold. NPCs also offer special rewards for each level of the upgrade process. This reward can be rerolled once and will use the same materials as the first item.
Rerolling
A player is able to reroll any item acquired in the game if they have enough tokens to do so. If an upgraded item is to be rerolled, it will be exchanged for an equivalent version at a level 1 of the same item in another set. Reroll tokens are available in the store for a small amount of in-game currency. They are not refundable. The new item will have the same bonus features as the previous one, but the stats will differ.
Players can change the identity of equipment in addition to rerolling it by interacting with an NPC upgrader. This will change the identification from an armor to a weapon or vice versa, all the while keeping its basic stats and required attributes. The change will last for a long time and affect all characters that own the equipment.
Players can also increase the item level of any equipped device by obtaining upgrade components and interacting with the upgrader NPC of the item. The cost will differ based on the upgrade track, item type and number of crests. For weapons, each upgrade will add an additional 5percent to the damage.
An upgrade will make it more powerful however it can also decrease its quality. Therefore, it is important to strike a balance between the two. Certain items might not be worth upgrading at all and some will require to be upgraded to maximize their potential. For instance, a player might decide to upgrade a piece of breakpoint armor that has an interesting modifier (% chance to block or FHR) to discover what it could be.
The primary reason people play rerolls in Genshin Impact, or in any gacha-based game is that they're trying to get a specific character or weapon that they wouldn't otherwise be able to acquire. The process of obtaining these items can be expensive and time-consuming and the RNG gods do not always want to play ball. The only options are to spend real cash or grind a lot. Rerolling is extremely popular in Genshin Impact.

Leveling
You can choose whether to upgrade the weapon or armor when you upgrade an item. This feature isn't available in the current version of the game. I believe that this feature was designed to add some value to expensive and rare items. However, as most gear is replaced fairly quickly and can only be leveled up one level, you'll usually replace it before it becomes too old. It's not worth it to upgrade item s that have gem sockets since the value of the gem will outweigh the higher ilvl that comes with the upgrade.
When you click the upgrade option on an item, you'll see a small window with the item's upgrade template and the cost of crest and Valorstone to boost the level of the item. Armor and weapons will have different costs, with the former usually being more expensive. The upgrade template outlines the stats that can be added to an upgraded item, as well as its current base ilvl.
The cost of the Valorstone and the crest is calculated based on the current Ilvl of the item and the upgrade templates. In addition the ilvl of the new upgraded item will be decreased by the template's lvl reduction percentage. For instance an upgrade of 8% will reduce the weapon's ilvl by 8 to 8percent.
The item will get upgrades to other stats, like critical strike damage, PvE damage and block, parry, and dodge rating in addition to the base ilvl. Those increases are also dependent on the upgrade template.
In the upgrade template you can determine the amount of damage or defense that the item will receive after being leveled up. This is shown below the cost as well as the upgrade percentages. Aside from practice equipment, all other weapons and armor gain these same stats when upgraded. The value of these stats will be determined by the market, with a perfectly rolled perfect version of a weapon or piece of armor can command significantly more trade value than non-upp'd versions. The same is true for other pieces of armor such as circlets or tiaras.
