World of Warcraft Upgrades and Item Upgrading
Upgrades can boost the value of certain numeric stats on armor, weapons and rings. They also increase bonuses such as damage from PvE and crit chance.
For instance a weapon that has the upgrade template ending in % will suffer 3damage to attack each time it is upgraded (relative to its previous value).
The cost for upgrading items increases when they reach the current level of the item. The cost rises with item's level.
Components
Upgrade components can be added to trinkets, armor, and weapons in order to give them a boost in stats or an extra effect. These can be obtained by crafting, buying from vendors or trading with other players or looting. Some upgrades also have special cosmetic effects.
Upgrade components can only be used on equipment that has a slot. The item must be at least upgraded to blue level before a component can be used. Like other mods, upgrade components can only be used once and can't be used multiple times or replaced with upgrades. Infusions and Enrichments are a kind of upgrade component that can be used to upgrade non-amulet legendary and Ascended equipment, as well in some items that aren't ascended. Infusions and enrichments can be recovered by salvaging gear that is ascended or by completing an elite mission in the Prophecies, Factions and Nightfall campaigns.
A prefix or suffix may be added to an upgrade, which alters the name of the item it is applied to (for example, 'Canthan Armor Insignia,' is changed to Canthan Armor Minor Vigor). Certain upgrades boost an item's Mark Level or Rarity, allowing players create stronger versions of that equipment with fewer Upgrade Crystals than would be required to reach the same upgrade level through normal methods.
A 'boost upgrade' can alter the attack or defense characteristics of a weapon or armor. Once the player has completed the cutscene and defeated the Crazed Mechanist These upgrades can be made at the Portative Forging Station. These upgrades can be purchased by purchasing them in the cash shop or by collecting them from enemies when upgrading other gear.
The player can have up to five boost upgrades at a time. Each upgrade increases the likelihood that a higher-level version of the item will appear in the next reset. This gives players an incentive to upgrade their gear, even if they are unsure how much it will be improved after a reset.
The process of upgrading an item could be expensive and it is likely that the item will become obsolete or even break if the upgrade fails. Upgrade Crystals and assist powder are also destroyed when an upgrade fails. This is alleviated by the availability cash shop items that can double or even eliminate possibility of failure, as well as some upgrades that offer an additional benefit when they are inserted into an item.
Glyphs
Glyphs are upgrade elements that can be inserted into special sockets on the Paragon Board. Glyphs increase the power of nodes within a radius, which includes any pre-existing affixes. Glyphs can be upgraded in various ways, and we suggest getting them up to level 15 whenever you can.
In the final game you'll often discover that the best way to improve your gear is by placing Glyphs. They are the only upgrade component that can be upgraded directly to level 15, and they provide an enormous boost to your power and radius on the Paragon Board, enabling you to get higher nodes faster.
The majority of upgrades in the game can be replaced, however, Glyphs are only the one upgrade component that can be removed and re-placed without restriction. Only legendary equipment can be salvaged and rebuilt by using the aid of a Black Lion Salvage Kit.
The value of each Glyph is displayed when you select it from your inventory. You can replace it with a Glyph of the same rank or a higher rank, which will boost 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 tools for gathering unlimited use as well as through Faction Crypt raids. Every Faction Crypt can drop one of these Glyphs. There are some rare glyphs you can find in any of the Faction Crypts.
Once you have gotten the desired Glyphs you'll require them to be put on your gear. Each Glyph unlocks a unique bonus which will boost the stats of a specific set of nodes that are within the radius of the Glyph. Based on the Glyph the bonus will be +40 to one of your primary stats, or +25 to two of your secondary stats.
Glyphs boost all nodes connected to them, so it is best to place Glyphs in strategic spots on the Graph. This will increase the impact. Druids, for instance should position their Glyphs close to their primary damage nodes. They may also consider placing them near their primary damage nodes.
Leveling
The system of upgrading items allows players to improve the stats of specific items by putting upgraded components in them. This is referred to as "upping". Each upgradeable item comes with an amount that determines its final upgraded stats. Upgraded items are able to be leveled until they reach a maximum level of ilvl 385. Each level of an item requires different components, and the cost of upgrading increase with each level.
Some upgrades require an ingredient to be activated. This ingredient can be obtained by finishing Upgrade Recipes. These recipes can be found in the upgrade tab of a crafting table, or obtained from NPCs. Each completed Upgrade Recipe earns a number of Technology Points. These points can be used to level the item, and when enough are earned, the upgrade will be claimed and the additional bonuses will be added to the item.
When the player upgrades an item it is replaced with a new item of the same kind. The same armor can be transformed into an weapon or shield when upgraded. The new item also comes with its own bonus. This can be a downside in that the item could increase in price even if you don't require it.
Item upgrades can sometimes be rerolled, if the player has enough reroll tokens in order to do this. This will cause the item to be exchanged for a new one, with a level 1 base and a different set of bonuses. This can be useful however it shouldn't be done often as it could waste resources.
Some upgrades can be rerolled several times, increasing their value and giving players the ability to alter their gear. item upgrades of this is Dolphin's Gift, which gives an advantage when a player repeatedly enters and leaves the water (or is able to swim like a dolphin). It can be upgraded multiple times, each time increasing the max roll by 10 points. This item is highly important in PvP. A properly rolled version can be worth as much as 50x the value of a non-upgraded version.
Requirements
The item upgrade r allows players to increase the level of their equipment (armor, weapons trinkets, and weapons) above ilvl 385 by providing the appropriate currency to the NPC. Upgrades to armor set pieces increase its base defense and weapon upgrades items increase their base damage as well as their strength and dexterity.
All items are upgradeable up to five times, with the exception for hero gear, which can be upgraded eight times. Every when you upgrade an item it is given a chance to fail--the failure rate increases the farther you go over the maximum amount of upgrades. Failures will result in the item reverting to its original condition, which requires the user to spend more materials than they would have to had they stopped upgrading at the maximum amount of upgrades.

If an item does not upgrade, the amount of accumulated experience in its growth bar is reset to zero. Additionally, the item will lose any gained bonuses such as crit chance, attack damage, as well as all other effects that are associated with that effect (for instance, a higher healing over time or speed of reload). However, the player can continue to use the weapon or armor after the failure.
Whenever an item is upgraded, the upgrades are applied from lowest to highest. This means that, when a weapon gains an increase in the chance of crit, the increase is applied prior to any increase in attack damage. Slots is a brand new attribute that has been added to the definitions of items. The value is calculated each time an upgrade occurs.
The amount of resources required to upgrade an item is determined on the rarity rating as well as the number of upgrade slots. The upgrade cost for non-premium products is equal to the base value of the upgrade. For upgrade item , a standard equipment item might have 5 upgrades with a cost of 25,600 Technology Points and a 4x Quality Improvement Chance. Hero grade items will have a much lower cost for each upgrade.
Premium items have different upgrade requirements than standard gear--for instance, they might require fewer sowels, but they will require more minerals and erons. However, players will have to visit the NPC [Armorthe ] Boboko in Central Flarine with each piece of equipment they wish to upgrade. In addition to the upgrade cost mentioned above, each equipment upgrade requires an individual amount of ingredients needed to upgrade.
