Item Upgrade in World of Warcraft Item Upgrade is a system which allows players to upgrade their armor, weapons and trinkets over what they can get from Mists Of Pandaria or Warlords Of Draenor. It requires crests and currency, and can be completed at any NPC that upgrades items. Items with high requirements (eth titans, for instance) generally increase in value after upgrading. Items with lower requirements receive a slightly lower value since they can be rolled perfectly regardless of upgrading. Reroll toke
