We’ve recently deployed a new system that allows World of Warcraft players to recover items that they mistakenly sold, destroyed, or disenchanted: Battle.net Item Restoration. With this new self-service option, the recovery of such items is fast and easy.
This restoration option may only be used once every 30 days on active World of Warcraft accounts that are in good standing. With items that were accidentally disenchanted, the new system can be used to request a review by Customer Support for restoration. As this option has a limited availability and use, we still encourage caution when selling, deleting, or disenchanting items.
You can read all about this new service in our detailed support article: Battle.net Item Restoration.
