World of Warcraft Item Upgrades
Item upgrades are a way to increase the stats of an item. Depending on the upgrade type, it may raise an item's Mark level or Rarity and boost additional stats.
Upgrading gear in The War Within requires a set number of Flightstones and Crests and each item has an upgrade track. Each upgrade increases the price of the next item upgrader mod by a specified amount.

When an item upgrader mod is upgraded, its basic stats are increased in value. This value is the total of all of its leveled up advantages (attack, magic attack and defense). Upgrades can be costly, depending on who you hire and what you do. This is due to the sheer number of perks that need to be changed in order to upgrade item an item.
The level of an item is a widely used measurement of power and can be found on all item tooltips. It can also be used to limit how much PvP gear players are able to wear as PvP is restricted at a lower level.
