World of Warcraft - Item Upgrade
The upgrade feature for items allows players to increase the item level for equippable weapons or armor. This improves the effectiveness of the gear, as well as sometimes adding buffs or the rerolling of an affix.
It is important to keep in mind that upgrading common gear isn't always worth it. Rare and exclusive equipment can quickly outperform the standard equipment and upgraded magic.
Cost
When a player upgrades an item, they must spend Gold to upgrade the item. The cost of upgrading an item is contingent on its current level and the upgrade type selected. Upgrades to weapons are generally cheaper than upgrades to armor since weapons have less requirements. The amount of Gold required for upgrading increases as the item is upgraded to the next level.
Upgraded items will also have enhanced stats that can boost its performance in a variety of ways. This may include increasing its attack power or critical strike chance. In addition an upgraded item might be able to provide extra buffs for its equipped unit. These upgrades are able to be used for a variety of reasons, including to boost the overall strength of a particular or group unit. They can also affect the overall the gameplay.
The items can be upgraded at any NPC that is an upgrader in the game. In general, these NPCs are located in capital cities or major questing areas. You can also find upgrades for items by visiting dungeons that have high-level bosses, and speaking to NPCs in the garrisons of your faction.
The item upgrade system in World of Warcraft provides players with the option of upgrading the level of armor, weapons and trinkets. The process is similar to that of gear reforging in Mists of Pandaria and Warlords of Draenor however, instead of using the currency that is appropriate players must visit an NPC to upgrade their items to complete the process.
Upgrades to items can be expensive, particularly when it comes to weapons and armor. Depending on which upgrade track you select, each level increase will cost Crests or Valorstones. The cost are prohibitive for those who don't have the funds or are unwilling to grind.
Fortunately, the game allows players to reroll an upgraded item with an exclusive tool within the menu of items. This option replaces the upgraded item with a level 1 version that offers different bonus effects. This can be useful to get higher scores on items that have been upgraded, but it can also be a waste of money.
Requirements
Upgrading is the process of increasing the level of items that can be equipped such as trinkets, weapons, and armor. This can boost their effectiveness which makes them more powerful in battle. Players can upgrade gear by spending appropriate currencies at an NPC that sells upgraders for items. However, players should be aware that certain upgrades require special requirements.
Initial upgrades only boost the stats of the base item by one level. Later upgrades provide more significant enhancements. Upgrades from levels 3 to 6 will boost the weapon's damage plus two levels. A bonus stat will also be added to the upgraded item based on its level. This bonus is a mix of a guaranteed substat and random generated stats that can vary from upgrade to upgrade.
A player can reroll an upgraded item by using a Reroll Token to exchange the upgrade for a new version. The new item comes with distinct set of bonuses, as well as a lower level of the item. The rerolled item also has different requirements for strength and dexterity. It is important to remember that the rerolled item does not retain its original level or even a fraction of its resources.
Rerolling upgraded items is only possible if the item that was upgraded was an Epic, Rare or Unique. Extraordinary items are also eligible for rerolling, but their original stats will be replaced by a flat bonus. This means that rerolling an item that is Rare item will result in a Normal version the same type, while the rerolling of an Epic item will result in an elite version of the same type.

A newly upgraded item could have extra modifiers, which could further boost its stats and boost its performance. These additional modifiers do not come with the upgrade price. You can purchase them at the Trading Post, or through other players. Alternatively, they can be earned through completing certain tasks in the game.
To upgrade an item of equipment, you need to visit the NPC [Armor] Boboko in Central Flarine. improve armor will need Power Dices depending on the item. (Dice 6 are dropped by monsters 21+, Giants and Bosses; Dice 12 from Bosses). You will also require different amounts of Minerals, Erons and Giants.
Time
Upgrades to items can be used to improve the performance of your equipment and ship without the need to upgrade them. They're not cheap, but they can be an effective way to increase your stats and not have to spend as much time fighting. It's crucial to understand the costs and benefits of upgrades to your item prior to investing money or effort.
Each upgrade boosts the stats of an item by a certain amount, and also offers the 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 increase in another. It's best to focus on the top-performing items in your slot first, since they will provide a greater return on your investment.
You can view the time required to complete an upgrade by opening your inventory and selecting an item such as a ship, weapon, or accessory. The upgrade window will display the progress and expected completion time. In some cases you may be capable of speeding up the process by using a Glyph.
Black Lion Salvage or Ascended Salvage offer a salvage kit that allows you to salvage all or a portion upgrade components. However, this does not include legendary equipment and upgrades which can be retrieved using an Upgrade Extractor or by recovering them through the appropriate karma merchant.
Enjoy the Benefits
Upgrades to items reward players with a range of items and currencies. In addition, every upgrade has a chance to provide a random extra stat bonus. The amount of bonus is different for each upgrade, and is generally higher for rare items. The players can perform a Great Vault search to see whether an item is upgradeable prior to spending tickets. The search can assist in determining whether the item is of a specific class and whether the player could benefit from a particular upgrade.
During the upgrade process, an item will gradually grow closer to the next stage, but it is not always able to reach its full upgrade bar. This process uses Growthstones and Sollant but there is a 10% chance of obtaining a fully upgraded item after just one cycle. The more levels that an item gains the more powerful its stat value will be, and the more items that can be upgraded.
Upgrade components can be integrated into armor, weapons and trinkets to give an attribute benefit or an additional effect while the equipment is in use. Certain upgrade components also have cosmetic effects. Upgrade components are available by crafting, buying from vendors or the Trading Post, looting or receiving as a gift. Players can also retrieve upgraded items by using an Upgrade extractor, or salvage with a high-tier salvage kit. Glyphs, which are placed in gathering tools, can be freely exchanged without restriction.
A player can turn an item into a different upgradeable item by selecting it and pressing the green button with an arrow that indicates reroll. This will alter the layout of the game and allow players to choose up to six items for "recycling". The item that is recycled will be exchanged for a level 1 item of the same type. Recycled items don't keep their status or the amount of resources used to upgrade them.
An item's maximum upgrade level is determined by its tier and quality. Rare and Epic items are able to be upgraded up to level nine, while common items can only be upgraded to level six. Item upgrades are added to the base statistics of the item and won't increase after a specific point.
