World of Warcraft - Item Upgrade
The feature of upgrading items allows players to boost the item level for equippable weapons or armor. This increases the stats of that gear, as well as sometimes adding buffs or rolling an affix again.

Cost

Upgrades to weapons are usually cheaper than upgrades to armor, since weapons have lower requirements. The amount of Gold required to upgrade an item increases when the item is upgraded to an upper level.
Upgraded items also come with enhanced stats that can boost its performance in a variety of ways. This could include increasing the power of its attack, critical strike chance, or damage per second. Additionally, an upgraded item may be able to give additional bonuses to its equipped unit.
