World of Warcraft - Item Upgrade
Item upgrade allows players to raise the item level of armor and weapons that can be equipped. This boosts the stats of the item and sometimes adds buffs or rerolls to an affix.
It is important to note that although you can upgrade your magic and common equipment, it is generally not worth the cost. Rare and unique gear will quickly outclass upgraded magic and common gear.
Cost
The player has to spend gold to upgrade an item. The cost to upgrade an item depends on the item's current status and the type of upgrade. Upgrades to weapons are typically cheaper than upgrades to armor because weapons have lower requirements. The amount of Gold needed increases as an item is upgraded.
A new item will also have increased stats, which can boost its performance in various ways. This may include boosting its attack strength or critical strike chance. A upgraded item can also provide additional buffs to the unit it's equipped with. These upgrades can be utilized for a variety of reasons for example, to increase the overall power of a particular or group unit. They also can have a major impact on the gameplay.
Items can be upgraded at any NPC that is an upgrader in the game. Generally these NPCs are found in capital cities or major questing locations. You can also find upgrades for items by visiting dungeons that have high-level bosses, and speaking to NPCs in garrisons of your faction.
The World of Warcraft item upgrade system allows players to improve the quality of weapons, armor and trinkets. This process is similar to gear reforging process in Mists of Pandaria or Warlords of Draenor. However instead of using currency, players have to visit an item upgrader to complete the process.
Upgrades to items can be costly, particularly when it is related to armor and weapons. Based on the upgrade path each step in level of the item could cost many Valorstones and crests. The total costs can be a major burden for players who don't have the resources or are unwilling to grind them.
The game lets you roll a new item by using a special tool from the items menu. This option allows you to exchange the upgraded item with an equivalent level 1 version that has an additional set of bonus effects. This is a great way to get better rolls on items that are already upgraded. However, it can be a waste of time.
Requirements

Exceptional items can also be allowed to be rerolled, but their original stats will be replaced by an uninvolved bonus. Rerolling a Rare item will result in a Normal version of the same kind, while rolling an Epic item will result in an elite version of the same type.

Time is an important factor.

Rewards
The upgrading of items rewards players with currency and a range of items. Every upgrade has a chance to award an unspecified stat bonus.

Uncommon items can be upgraded up to a maximum of level six, while Rare and Epic items can be upgraded up to level nine. The upgrades to items are added to the base stats of the item. This means that they won't increase further after a certain level.
