Path of Exile Item Upgrades
The performance of a variety of Path of Exile items can be improved by upgrading the performance of them. They can be a fantastic source of additional damage or more AD or even more affixes.
Rare-grade equipment is often superior to upgraded Common or Magic equipment due to their high demands.
Armor
Armor upgrades are a kind of upgrade that can be used on weapons and armor items. They boost the performance of the item that they're attached to. Upgrades to armor can be found in the world of the game and can be purchased from Blacksmiths at bonfires. Alternately, they can be rescued from items with upgrade components inside them, using a specialist or more powerful salvage kit.
The level of an armor's or weapon's upgrade determines the amount of damage it can absorb. The absorption of damage by an armor piece will increase when it's upgraded to the maximum upgrade level. It is important to keep in mind that this will increase the weight of the armor, so it must be more heavy.
There are a few different kinds of armor upgrades available in the game and they all have different effects. For instance, certain upgrades give the armor a certain amount of health points while others will make it stronger and lighter. The type of armor upgrade that an item will receive will be indicated by the name of the upgrade, as shown in the table below.
Some of the upgrades also require magic or a combination of technology and magic, as indicated by the "Magic" and "Hybrids" entries in the table below. Some upgrades also require charges for use. They are referred to as "Charges" entries in the table. These charges are either updated daily or never expire based on the upgrade.
The cheapest way to upgrade armor is to use Iron Ore, which can be found by exploring the area and looting small loot chests. Titanium is more expensive but can be found at the smelters of Orgrimmar and Stormwind City. Some upgrades, such as the Reforge and the Hot Potato Books, can only be applied to higher level armor pieces. These upgrades can give players a significant improvements in stats and are worth the cost.
Upgrading a piece of armor to its maximum upgrade level will greatly increase its defense capabilities but the wearer must be aware that putting on weight will drastically reduce its agility and speed. Therefore, item upgrader is generally not recommended to upgrade most armor pieces that are higher than +9 since the added defense is typically not worth the extra weight and power cost of the upgrades needed.
Weapons
Weapon upgrades allow players to improve the effectiveness of certain aspects of an weapon. For example an upgrade could increase the damage dealt by the shells of a shotgun or the accuracy of a sniper rifle. this link have special upgrades that enhance their inherent qualities. Frictionless materials (improves stability, and reduces the possibility of overheating) and Kinetic coils (increases the projectile's speed to cause more damage) are two examples.
The majority of weapon upgrades require a whetblade. It's one of three Power Dices and a different amount Minerals and Erons. These can be obtained by completing side quests or by killing a certain number of monsters and bosses.
To upgrade a weapon, equipment set piece or Whetblade you need to visit the NPC [Armor] Boboko located in Central Flarine, and pay her an upgrade fee that is a certain number of Bars. The higher the upgrade level, the higher the number of bars you will need to complete the upgrade. If you have multiple upgrade materials The cost of upgrading will be lower.
In Chapter 2: Season 5, the ways to upgrade your equipment and weapon sets has changed a bit. In the past you could go to an Upgrade Bench and pay a set amount of Bars to upgrade your equipment or weapon to a higher level of rarity. You could do this until the weapon or equipment reached its maximum upgrade level and at that point, the upgrades would be reset.
You can still do this but the process is based on RNG and low on agency. It is better to purchase gear with minimal upgrade levels but with high base scores and stat distributions. These items will have a better chance of giving you the highest tier blessings and perks.
Most players will want to prioritize weapon upgrades for the weapons they are most likely to use to allow them to progress quicker. In addition players, they should think about upgrading the weapons they use with their teammates to make them more powerful and effective. Shepard, for example should upgrade his M92F to unlock the Beretta M93R. This will make the weapon more effective when accompanied with biotic specialists like Grunt and Tali.
Jewels
Jewels are utilized in the armor's sockets and weapons, increasing a stat and providing secondary effects. Jewelry crafting is a method of creating them. You combine a gemstone with a number specific reagents on a table. The higher the tier of the jewel has, the more powerful its secondary effect. These reagents can be gotten from Treasure Goblins and World Bosses around the world, or through salvaging Legendary Gear. You can also purchase them from The Jeweler in exchange for Scattered Prisms and gold.
The quality of a gem can be improved by the Jeweler, in stages that range from Crude to Royal. The boosts to stats will differ depending on the tier the jewel is at when it's inserted into jewelry, weapons or other gear.
All levels of jewels are crafted at the Jeweler and Jeweler's Workshop, with the exception of the rare and legendary jewels that require you to be at a certain level to qualify for them. Like other upgrade components jewels are able to be swapped with a jewel of the same kind without damaging it. However it is only possible to replace the jewels in a piece of equipment once.
Using more jewels in a move can make it feel more comfortable, and is often done to enhance the aesthetics of the movement. In addition to enhancing performance, the diamonds create an area that is stronger than steel, so the repeated friction from pivots doesn't damage them as easily.
In addition to the above upgrades, the player can also obtain glyphs for their weapons and shields from a Glyphmaster. These glyphs offer a small boost and can be exchanged, however they're not guaranteed to appear as loot. Glyphs, like jewelry, can be upgraded at the Jeweler to exchange Scattered Crystals and gold. Glyphs can also be taken out, which returns them to the inventory. Other upgrade components such as traits or aegis cannot be exchanged and can only be found by using an Upgrade extractor or salvaging using the Black Lion Salvage Kit or Ascended Salvage tool.
Trinkets

Trinkets can be used to provide your hero with various small, but useful benefits. You can find them in the starter area as loot or personal story rewards. They can also be obtained from vendors and by completing road interaction. They may also be crafted by jewelers, and then found or purchased from the Trading Post.
The first trinket a player will unlock is the cloak. It provides a tiny but beneficial boost in speed of movement and the ability to escape. After that, they can acquire rings, amulets, and necklaces in a similar manner to the way a player acquires armor and weapons. Each piece of gear comes with one upgrade slot that can accommodate either a universal upgrade or a jewel upgrade. Universal upgrades are smaller and can be used on any piece of equipment. Jewels are not upgradeable or replaced and only work with certain trinkets.
These trinkets also provide additional bonuses and abilities that are active when the hero is not in combat. This lets a hero become more efficient even when not in combat. It can also make up for the absence of strong slot in the talent tree or team that are normally filled by the hero's best stats.
As a general rule, trinket upgrades should prioritize BiS (Best in Slot) items you won't replace anytime soon. Next, any items that have desirable statistics aren't as important as the iLevel for the item to be upgraded. This is particularly true if an item has multiple stats that you'd like to upgrade, as it's usually better to upgrade a single important stat rather than two sub-optimal ones.
In the beginning of the game, players who are in the jungle will typically want to upgrade their trinket to a red in the middle and top players usually choose either a pink or green ward (depending on the game's matchup). These choices will have a significant impact on the hero's ability to control his map.
Apart from the items listed above, players may also find other trinkets throughout the game in the form of trophies and awards. These can be obtained by completing certain milestones in the story. For instance, completing a chapter’s main quest or defeating a boss. They can be viewed by selecting the appropriate achievement from the reward tab of the hero menu.
