World of Warcraft Upgrades and Item Upgrading
Upgrades can boost the value of weapons, armors and rings. They also increase bonuses such as crit chance and PvE damage.
For example, a weapon with the upgrade template ending in % will take on 3% attack damage every time it is upgraded (relative to its previous value).
The cost of upgrading an item increases as it reaches the current level of the item. The cost rises with item's level.
Components
Upgrade components are items that can be put into armor, weapons, and trinkets to give an extra stat boost or effect when they're used. They can be obtained through crafting, buying from vendors or trading with other players or looting. Some upgrades can also be accompanied by special cosmetic effects.
Upgrade components can be inserted into any equipment with a slot for them. The item must have been at least upgraded to the blue level in order for the component to be applied. Upgrade components, unlike other modifications, can only be applied only once. They are not able to be replaced or applied several times. Infusions and Enrichments are a kind of upgrade component that can be used to upgrade non-amulet legendary or ascended equipment, as well in some items that aren't ascended. Infusions and enrichments are recovered by salvaging gear that is ascended or by completing an elite mission in the Prophecies, Factions and Nightfall campaigns.
An upgrade can have a prefix or suffix, modifying the name of the equipment to the upgrade (for instance 'Canthan Armor Insignia" becomes Canthan Armor of Minor Vigor). Certain upgrades can increase the Mark Level or Rarity of an item, which lets players to create stronger versions using the smallest amount of upgrade crystals than they require to reach the same level using standard methods.
A boost upgrade is a way to alter the attack or defense properties of a weapon, or armor. Once the player has completed the cutscene and defeated Crazed Mechanist These upgrades can be created at the Portative Forging Station. They can be dropped by enemies when upgrading other gear or purchasing them from the cash shop for 500 upgrade crystals.
Each upgrade increases the probability that a higher-tier version of the item will be available at the next reset. This gives players the opportunity to upgrade their gear even when they're not sure what will be improved following an update.
The process of upgrading an item could be costly and it's possible that the item will become obsolete or even break if the upgrade is unsuccessful. Upgrade Crystals and assist powder are also destroyed when the upgrade fails. Cash shop items can be used to reduce or eliminate the chance of failure. Certain upgrades also provide the player a bonus if they are they are reinserted.
Glyphs
Glyphs are upgrade components that can be placed in special sockets on the Paragon Board. Glyphs boost the effectiveness of all nodes in the area around them as well as existing affixes on equipment. Glyphs can be upgraded in many ways, and we suggest upgrading them to 15 levels as soon as you can.
You will often find in the endgame that placing Glyphs is the best way to upgrade your gear. These are the only upgrade component that can be upgraded up to level 15 and provide an enormous boost to your power on the Paragon Board.
Glyphs, the sole upgrade component which can be removed without restriction and then replaced with no restrictions are the most commonly used. Only legendary equipment can be salvaged and replaced with the aid of a Black Lion Salvage Kit.
Each Glyph has a particular range of values it can improve a statistic by. The value is displayed when you select the Glyph in your inventory. You can choose to replace it with a different Glyph of the same rank or a higher rank, which will increase the overall value of the glyph.
There are Glyphs in the Black Lion Trading Post, as part of the Gem Store purchase or bundle with certain unlimited-use gathering tools as well as through Faction Crypt raids. Each Faction Crypt has the chance of dropping one of the many Glyphs and there are some rare glyphs to be found in the form of drops from any of the four Faction Crypts.
Once upgrade item have obtained the desired Glyphs you will need them to be placed on your gear. Each Glyph will unlock a unique bonus that boosts the stats of a specific set of nodes that are within a radius of the Glyph. This will either be +40 for one of your primary stats or +25 for two of your secondary stats depending on the Glyph.
Using the Glyph will boost all nodes connected to it, and you should try to place your Glyphs close to key nodes on the Graph to maximise the impact. Druids for instance should put their Glyphs close to their primary damage nodes. They might also consider placing them near their critical damage nodes.
Leveling
The upgrade system for items allows players to increase the stats of specific items by putting upgraded components in them. This is commonly known as "upping". Every upgradeable item has an amount that determines its final upgraded stats. Upgraded items can be upgraded up to a maximum of 385 ilvl. Each level of item requires different components, and upgrade costs increase with each level.
Some upgrades require an ingredient to be activated. This ingredient is obtained by completing Upgrade Recipes. These recipes can be found in the upgrade tab of a crafting table, or bought from NPCs. Each completed Upgrade Recipe earns some Technology Points. These points can be used to upgrading an item. Once enough points are earned you will be able to claim the upgrade and also receive the bonuses.
When the player upgrades an item to a higher level, the original item is replaced with a different item of the same kind. This means that the same piece of armor will be transformed into an weapon or shield once upgraded. The new item will also have its own set bonus. This could be a drawback, as the item can become more expensive even if you don't require it.
The upgrades to items can be rerolled if the player has enough tokens to be able to do this. This will cause the item to be exchanged for a brand new one, with a level 1 base and a completely different set of bonuses. This can be useful for certain items, but it's not something that should be performed frequently, since it can waste many resources.
Certain upgrades can be rerolled several times which increases their value and allowing the player to customize their gear. Dolphin's Gift is a good example, as it provides a buff if the player is repeatedly in or exits the water. It is possible to upgrade it several times, each time increasing the maximum roll by 10 points. This item is very useful in PvP. A perfectly rolled version can be worth up to 50x the value of the non-upgraded counterpart.
Requirements
The item upgrade r lets players increase the level of their equippable equipment (armor weapons, armor, and trinkets) beyond ilvl385 by handing over the appropriate currency to the NPC. The upgrade of armor set pieces will also boost the defense base of the item, and upgrading weapons will increase the base damage and required strength and dexterity to meet the upgraded equipment's requirements.

Each item can be upgraded up to five times, except for hero equipment, which is able to be upgraded eight times. Each each time you upgrade an item it has an opportunity to fail. The failure rate increases the more you exceed the maximum number of upgrades. Failures will cause the item to return to its original condition and the player having to pay for more items than if they stopped upgrading after the maximum amount.
If an item is not upgraded, the experience bar in its growth bar will reset to zero. The item also loses any bonuses it has gained like crit chance attack damage, other effects (such as increased heal over time, or the speed of reloading). However, the user can continue to use the weapon or armor after the failure.
When an item is upgraded the upgrades are applied in order from the lowest to the highest. This means that when a weapon is upgraded, if it receives a crit chance boost, the increase will be applied before any damage to attack increases. Slots is a brand new attribute that was added to item definitions. The value is recalculated each time an upgrade occurs.
The amount of resources needed to upgrade an item are dependent on its rarity score and upgrade slot count. The cost of upgrading non-premium equipment is equivalent to its value. For instance an item that is commonplace could have five upgrades at a cost. 25,600 Technology Points and a 4x Quality Improvement Chance. Hero grade items will come with a much lower cost for each additional upgrade.
Premium items could have different upgrade requirements than regular gear. For example, they may need fewer sowels, but more minerals and orons. Regardless, the player will need to visit the NPC [Armor] Boboko in Central Flarine with each piece of equipment they wish to upgrade. Each upgrade to equipment requires different amounts of upgrade ingredients in addition to the expenses mentioned above.
