Item Upgrade in World of Warcraft
item upgrades upgrade is a method that allows players to increase the level of their weapons, armor and trinkets above what they can acquire from specific Mists of Pandaria and Warlords of Draenor sources. It requires crests and currencies and can be completed at any NPC that upgrades items.
Items with high requirements usually have higher value following upgrading (eth titans, for instance) while items with low requirements often receive slightly less value as they can be perfect rolled regardless of upgrading.
Reroll tokens
Reroll tokens are a special item upgrader kit that can be used to enhance an Best item upgrader. They can be obtained from event rewards and monsters. They are available in three different types: rare, enhanced, and legendary. When a player has a reroll token, they can right-click on a Satanic or Angelic item level upgrade and select the option to reroll the quality of the item upgrading (https://algowiki.win). This will drain the token used to reroll.
