World of Warcraft - Item Upgrade
The upgrade feature for items allows players to boost the item level for weapons that can be equipped or armor. This increases the stats of that gear, as well as sometimes adding buffs or rerolling an affix.
It is important to remember that upgrading magic and common gear is not always worth it. Rare and exclusive gear will quickly outclass upgraded magic and common gear.
Cost
If a player wants to upgrade an item, they have to pay Gold for the upgrade. The cost of upgrading an item is contingent on its current level as well as the upgrade type selected. For instance upgrading a weapon is typically be cheaper than upgrading armor, as weapons require lower levels of skill. The amount of Gold needed increases as an item is upgraded.
Upgraded items will also have upgraded stats that will improve its performance in various ways. This could mean increasing the power of its attack critical strike chance, or damage per second. Additionally, an upgraded item may be able to offer additional buffs to the unit it is equipped with. These upgrades are able to be used for a number of reasons, including to boost the overall strength of an individual or group unit. They can also have a major impact on the gameplay.
The items can be upgraded at any NPC who is an upgrader in the game. These NPCs are located in the major questing areas or capital cities. Players can also find upgraders by visiting dungeons with high-level bosses, and by talking to NPCs in their garrisons of their faction.
The upgrade system for items in World of Warcraft provides players with the option of upgrading the levels of weapons, armor, and trinkets. This process is very similar to that of gear reforging in Mists of Pandaria and Warlords of Draenor, but instead of using the currency appropriate to the task players need to visit an item upgrader NPC to complete the process.
Upgrades can be costly particularly for armor and weapons. Based on the upgrade path you select, each item upgrade can cost Valorstones or Crests. The costs are prohibitive for those who don't have the money or are unable to grind.
Fortunately, the game lets players play a reroll of an upgraded item by using a special tool in the menu for items. This option exchanges the upgraded item for a version at level 1 which comes with a different set of bonus effects. This is useful for obtaining better scores on items that have already been upgraded, but could be a waste of money.
Requirements

The process of upgrading items that are equippable such as weapons, armor and trinkets is to increase the item level. This can increase their power and make them more effective in battle. Players can upgrade their gear by paying the appropriate amount of currency at an upgrader. Players should be aware the fact that certain upgrades require special requirements.
The initial upgrades only boost the stats of the item's base by one level, however later upgrades provide more significant increases. For example, upgrading a weapon from level three to level six can increase the weapon's damage by plus two levels. Additionally the upgraded item will get an additional stat that is based on the level at which it was purchased. This bonus is a combination of a guaranteed additional substat and a random statistic that will change in value from upgrade to upgrade.
Reroll Tokens can be used to reroll an item which has been upgraded. The new item has a different set of extra bonuses, and is of a lower level of the item. The rerolled item will have different requirements for strength and dexterity. It is important to note that the rerolled item will not be able to maintain its strength or use any wasted resources.
Some upgraded items can only be rerolled only if the original item was a Unique Epic, Rare or Rare. Exceptional items can also be allowed to be rerolled, but their original stats will be replaced with a flat bonus. This means that rerolling a Rare item will result in a Normal version the same kind, while rerolling an Epic item will result in an Elite version of the same kind.
Upgraded items could have additional modifiers that can improve their performance and improve their stats. These additional modifiers don't come with the upgrade cost. They can be acquired through doing quests, purchasing them at the Trading Post or from other players. They can be earned through completing specific missions in the game.
To upgrade an item of equipment, you need to visit the NPC [Armoror Boboko located in Central Flarine. Depending on the type of item, you'll need one or more Power Dices (Dice 6 is available from monsters 21+ and Giants; Dice 12 is available from Bosses). You will also require various quantities of Minerals and Erons.
upgrade item is an important factor.
Upgrades to items are a method to boost your ship's performance and gear without having to level them up. They're not cheap, but they can be an effective way to increase your stats without having to spend a lot of time fighting. It's important to know the cost and benefits prior to investing your money or time.
Each upgrade increases the base stat of an item by a certain amount, and also gives a chance to gain a bonus substat increase. The additional substat is randomly assigned and could range from a tiny increase in one stat to an even greater boost in another. It is best to concentrate on the top-performing items in your slot first, as they will provide a greater return on your investment.
You can check the time it takes to complete an upgrade by opening your inventory and selecting an item such as a ship, weapon, or accessory. The upgrade window will show the expected completion date and progress. In some cases you might be able to speed the process by using a Glyph.
It is also possible to retrieve any or all upgrade components from an item by using a specific high-end salvage kit, which is offered by Black Lion Salvage and Ascended Salvage. This is not applicable to legendary equipment or upgrades that can be recovered with an upgrade extractor or making a claim with the appropriate Karma merchant.
Rewards
Upgrades to items reward players with a variety of items and currency. Each upgrade also has the chance to grant a random stat bonus. The value of the bonus differs for each upgrade, and is generally higher for rarer items. Players can use a Great Vault search to see whether an item is upgradeable prior to spending tickets. The search will help determine whether the item is of a particular tier and whether the player could benefit from upgrading to a specific upgrade.
During the upgrade process, an item will gradually grow closer to its next level but won't always reach a fully upgraded bar. This process makes use of Growthstones and Sollant but there's a chance of achieving a fully upgraded item after just one cycle. The higher the level an item is upgraded to the higher its boosted stats value and the more items it is able to upgrade to.
Upgrade components can be added to trinkets, armor, and weapons in order to gain an attribute bonus or to create a unique effect when the equipment is worn. Some upgrade components have additional cosmetic effects. Upgrade components are available by crafting, buying from vendors or the Trading Post, looting or receiving them as gifts. Players can also recover upgraded items by using an Upgrade extractor or salvaging using a salvage of a higher tier kit. Glyphs that are positioned on tools for gathering can be freely swapped.
By selecting the item and pressing the green button with a an arrow that rerolls players can roll it into an upgradeable item. This will alter the layout of the game and let players select up to six items to be used for "recycling". The item that is recycled can be exchanged for a level 1 item of the same kind. Recycled items will not keep their status or the amount of resources used to upgrade them.
The maximum level of upgrade for an item is determined by its tier and the quality. Uncommon items can be upgraded up to the maximum level of six, while Rare and Epic items can be upgraded up to level nine. The item upgrades are added to the base stats of the item. This means that they won't grow more after a certain point.
