World of Warcraft - Item Upgrade
The upgrade feature for items allows players to increase the level of equippable weapons or armor. This increases the effectiveness of the equipment, and also sometimes adding buffs or rerolling an affix.
It is important to remember that upgrading magic and common gear isn't always worth it. Rare and exclusive equipment can quickly outperform the standard equipment and upgraded magic.
Cost
The player has to spend gold to upgrade an item. The cost of upgrading an item is contingent on its current level and the type of upgrade selected. Upgrades to weapons are usually less expensive than upgrades to armor, since weapons have lower requirements. The amount of Gold required for upgrading increases when the item is upgraded to an upper level.
A newly upgraded item will also have improved stats, which can boost its performance in various ways. This can include boosting its attack strength or critical strike chance. Additionally an upgraded item could be able to provide extra buffs for its equipped unit. These upgrades can be used for a number of reasons, including to boost the overall power of an individual or group unit. They also can be a significant influence on gameplay.
The NPC for upgrading items can be located in the game. In general these NPCs are found in major cities or questing locations. Players can also find upgraders in dungeons that have high-level bosses and by chatting with NPCs in their garrisons of their faction.
The system of upgrading items in World of Warcraft provides players with the possibility of upgrading the levels of weapons, armor, and trinkets. This process is largely identical 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 for upgrading items to complete the process.
Upgrades can be costly especially for weapons and armor. Based on the upgrade path you select, each item upgrade can cost Crests or Valorstones. The total cost can be very prohibitive for players who do not have the funds or are unwilling to grind them.
The game lets you play a reroll of an upgraded item using a special tool from the menu of items. This option lets you exchange the upgraded item for an equivalent level 1 version that has a different set of bonus effects. This is useful for obtaining better rolls on items that have already been upgraded, but can be a waste of resources.
Requirements
Upgrading is the process of increasing the level of the items that are equippable, such as armor, weapons and trinkets. This can increase their stats which makes them more powerful in combat. Players can upgrade gear by paying the appropriate currency at an item upgrader NPC. However, players must be aware that certain upgrades have special requirements.
The earliest upgrades only increase the stats of the item's base by one level, but later upgrades offer more substantial boosts. For instance, upgrading a weapon from three to level six will boost the weapon's damage by two levels. A bonus stat will be added to the upgraded item based on its level. The bonus is a combination of a guaranteed extra substat and a random stat that will change in value from upgrade to upgrade.

A player can roll an upgraded item using a Reroll Token to exchange the upgrade for a new one. The new item will come with an additional set of bonuses and a lower base item level. The rerolled item will also have different requirements for strength and dexterity. It is important to note that the item rerolled does not keep its original strength or any of its wasted resource.
Rerolling some upgraded items is only possible if the item was upgraded was an Epic Rare, Rare or Unique. Exceptional items are also suitable for rerolling, however their original stats will be replaced by a flat bonus. Rerolling an item that is Rare or Epic item will result in a Normal version, and doing the same with the Epic version will result in an elite version.
A newly upgraded item could include additional modifiers that can further increase its stats and boost its performance. These additional modifiers are not included in the upgrade price. They can be acquired by questing, buying them on the Trading Post or from other players. Additionally, they can be earned through completing certain missions in the game.
To upgrade a piece of equipment, you need to visit the NPC [Armorto upgrade a piece of equipment, visit the NPC [Armor] Boboko located in Central Flarine. You will require Power Dices depending on the item. (Dice 6 can be dropped by monsters 21+, Giants and Bosses; Dice 12 from Bosses). You will also need various amounts of Minerals and Erons.
Time is a major factor.
Upgrades to items can be used to improve the performance of your gear and ship without the need to upgrade them. Although upgrading isn't cheap, it can be an excellent way to increase your stats without having spend as much time in combat. It's essential to understand the benefits and costs of item upgrades before you invest your money or time.
Each upgrade boosts the stats of an item by a specific amount and also offers a chance to gain a bonus substat increase. The random substat can vary from a modest increase to a significant boost. It is best to concentrate on the most effective items in the slot first, as they'll provide a greater return on your investment.
You can view the time required to complete an upgrade when you open your inventory and choose an item such as a ship, weapon or accessory. The upgrade window will display the estimated completion time and the progress. In some cases you might be in a position to speed the process by using a Glyph.
It is also possible to recover some or all of the upgrade components from an item using a special high-tier salvage kit sold by Black Lion Salvage and Ascended Salvage. This is not the case for legendary equipment or upgrades that can be recovered using an Upgrade extractor or by making a claim with the appropriate Karma merchant.
Take advantage of the benefits
Item upgrading rewards players with a range of items and currencies. In addition, every upgrade can grant a random extra stat bonus. The amount of bonus awarded is different for each upgrade, and it's usually more expensive for rarer items. Players can use the Great Vault search to see whether an item can be upgraded before spending tickets. The search will help determine whether the item is in a certain tier and whether the player will benefit from an upgrade.
In the process of upgrading an item will gradually grow closer to its next level but won't always reach a fully upgraded bar. This process consumes Growthstones and Sollant and Sollant, but there's the chance to achieve a fully upgraded item with only one cycle of growth. The higher the levels an item attains the more powerful its stat value will be and the more items can be upgraded.
Upgrade components can be integrated into armor, weapons and trinkets in order to give an attribute bonus or extra effect while the equipment is being used. Certain upgrade components also have cosmetic effects. Players can acquire upgrade items by crafting, purchasing from vendors or on the Trading Post, looting, or as rewards. In addition players can find upgraded items using an Upgrade Extractor, or salvaging them using a top-quality salvage kit. Glyphs that are placed on gathering tools are able to be swapped.
A player can turn an item into a different upgradeable item by selecting it and pressing the green button with an arrow for reroll. This will alter the layout of the game and let players select up to six items for "recycling". The item that is recycled will be exchanged with an item of level 1 of the same type. Recycled items will not keep their status, nor will the resources used to upgrade it.
The maximum upgrade level of an item is determined by the item's tier and its 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 item's base statistics and won't increase after a certain point.
