Item Upgrade in World of Warcraft
item upgrading upgrade is a feature that lets players increase the level of their weapons, armor and trinkets beyond the level they can get from specific Mists of Pandaria and Warlords of Draenor sources. It is possible to upgrade items using any time.
Items with high requirements generally get more value when upgraded (eth titans, for instance) While items with low requirements often receive slightly less value as they can be rolled perfect regardless of upgrading.
Reroll tokens
Reroll tokens can be used to upgrade an item upgrader kit. They can be obtained from events and monsters. They are available in three subtypes: rare, enhanced, and legendary. If a player owns a reroll token they can right-click on a Satanic or Angelic item upgrader and select the option to reroll the quality of the item upgrader kit. This will drain the token that is rerolling. Reroll tokens can be traded with other players.
The upgrade of an item upgrader mod can increase its stats and powers.
