Path of Exile Item Upgrading
In Path of Exile, item upgrading is among the best ways to improve your equipment without relying on big-ticket drops or trade. This article will teach you how to upgrade your items.
Upgrading equipment grants an additional bonus to the item's base stats. This bonus is based on the upgrade component's level and rarity.
Components
Upgrade components are the items that can make your weapons and armor more effective. You can acquire them by fighting off enemies, locating them in item spheres, or buying them from karma dealers. You can also salvage them from equipment that has the components, or by utilizing salvage kits of high-end quality, such as Black Lion Salvage Kit and Ascended Salvage Tool. In contrast to other items, upgrade components are not destroyed when removed from an item.
The main purpose of upgrade components is to enable an item to be upgraded however, they also serve other functions. They can be used to increase the level of experience gained from upgrading existing equipment or weapons. They can be forged to give additional bonuses. A crafted glyph can increase the upgrade chances of its target, and a boost upgrade increases the attack or defense attributes of a weapon.
By selecting an upgrade template from the GUI will let you bind it to an item. This will show the upgrade components that the item can be updated. Alternatively, you can utilize the workbench to select an upgrade template. In either scenario, an item will be upgraded when enough upgrade components have been gathered.
Each component has a distinct experience multiplier that affects the amount of experience an item gets when it upgrades with that component. Organic components, for example have more experience multipliers than mechanical components. It is therefore best to upgrade with organic components until you have reached the experience multiplier of the next rank of the equipment or weapon, and then change to mechanical upgrades.
Each item comes with a maximum upgrade number that is available for. The number of upgradeable items is determined by their upgradeable rank, and the kind of upgrade they are able to receive. The highest upgrade possible is a weapon that is the tier 10. However, the most commonly used upgrade for weapons is a tier 6 weapon and a tier 5 armor upgrade.
Sets
A set is a group of items that share a bonus. Each item in the set can be upgraded at least once and the upgrade will increase its guaranteed bonuses. The first time you upgrade an item, its primary stat will be +1. Following upgrades, the primary stats will be boosted even further (for instance the +1 bonus for 12+/13+/14+) and every time an item is upgraded one of its additional stats increases randomly.
Upgrades to a weapon may increase the damage base, which could be important for some builds. Weapons can't be upgraded for a higher maximum defence roll than their base. It's possible to increase the value of certain sets and unique items by upgrading them, but they're not always superior to a higher-level Runeword.
If you are upgrading an item that comes with bonuses the item can be rerolled a single time, and its guarantee will reset back to zero. The same power dies are used to roll an item as it would be used to increase its level. However the new item comes with different bonuses. Upgrades can be completed through the NPC [Armor] Boboko in the Central Flarine. To upgrade an item, you will require a power dice of each kind (Dice 4 or 6 drop from monsters 21+ and Giants; Dice 7 drops from bosses) and the proper amount of Minerals and Erons. These can be bought with Gold at the crafting table or in the Ultra Collection. The NPC will also offer a special reward for every tier that is completed of the upgrade process. This reward can be rerolled a single time, using the same materials as the original item.
Rerolling
If the player has enough tokens for rerolling, they can roll any item they've acquired during the game. If an item is rerolled, it will be replaced by an equivalent level 1 version from another set. Reroll tokens can be bought from the store for small amounts of in-game currency, but they are not refundable. The new item upgraded will still have the extra bonuses of the first however its stats will differ too.
In addition to rerolling items players can also alter the identification of any equipment by interfacing with an upgrader NPC. This will change the identification from a weapon to armor or vice versa, while keeping its basic stats and required attributes. The change is permanent and will affect all characters that have the gear in question.
The player can also upgrade their level of the item for any equipment that is equipped. This is accomplished by talking to an upgrader NPC, and then obtaining upgrade item s. The cost will vary depending on the upgrade track, item type and the number of crests. Each upgrade will add 5percent more damage to weapons.
Upgrades can boost the power of an item, however they can also reduce its quality. It is therefore essential to find a balance between the two. Certain items might not be worth upgrading at all, while others will need to be upgraded in order to reach their potential. For example one player might decide to upgrade a piece breakpoint armor with an interesting modifier (% chance to block or FHR) to discover what it could become.
The main reason people are able to reroll in Genshin Impact, or in any gacha-based game is that they're trying to obtain a particular character or weapon that they wouldn't otherwise be able to acquire. These items can be costly and time-consuming, and the RNG gods don't always want to cooperate. The only alternative is to invest money or grind extensively. Rerolling is very popular in Genshin Impact.
Leveling
You can decide to upgrade the weapon or armor after upgrading an item. This feature is not available in the current version of the game. I believe this feature was intended to increase the value of expensive and rare items. However, as most equipment is replaced quickly and can only be upgraded one level, you will generally replace it before it gets too old. It's not worth upgrading items with gem sockets, as the power of the gem will outweigh any increase in the level of.

You will be presented with a small box when you click on the upgrade option on an item. It will show the template for the item, its Crest, as well as the cost for Valorstone to raise the item's level. The cost will differ between weapons and armor, with the former usually costing more than the latter. The upgrade template outlines the stats that will be added to an upgraded item, along with its current base ilvl.
The cost of the Valorstone and the crest is calculated based on the current Ilvl of the item as well as the upgrade templates. In addition, the ilvl of the new upgraded item will be reduced by the upgrade template's lvl decrease percentage. For instance weapons with an 8% upgrade decrease will reduce its ilvl by 8 - 8 percent.
The item will receive upgrades to other stats, such as critical strike damage, PvE damages and block, parry, and dodge rating, in addition to the base level. Those increases are also based on the upgrade template.
In the upgrade template you can see 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. All weapons and armor apart from practice equipment get these stats when they level up. The value of these additional stats will be dictated by the market, with a perfectly rolled perfect version of a weapon or piece of armor able to command much more in trade value than unupp'd versions. Similar is the case for other pieces of armor such as tiaras and circlets.
