Item upgrading

Item upgrading provides players the ability to upgrade item levels of equippable items, such as armor, weapons, and trinkets above from specific Mists of Pandaria and Warlords of Draenor sources. Players can upgrade items by spending appropriate currencies at any item upgrader NPC.
As stats on items are based upon the item's level, upgrading an item's level will upgrade its stats as well.
