Token that can be redeemed for one item upgrade.
Upgrade tokens can be found in certain packages, supply boxes, and bounty and war rewards. A token can be used for one item upgrade, which will immediately upgrade the item without requiring any components or resources.
Tokens only work for the quality item they are assigned and lower, and have a level range they can upgrade to — there is no "one size fits all" token. For instance, a Good token is able to upgrade any Good items in its level range, but cannot upgrade a Superior item. Each token will upgrade the item by one level, and have a 5% chance of upgrading the item to maximum level.
To use a token, access the upgrade menu, select the desired item, and click the "Use an upgrade token" button. The button will not appear for items that do not have a token available for them.
