If you’ve collected a ton of Timewarped Badges during the anniversary event and were hoping to use them for Heirloom upgrades before Dragonflight, we’ve got bad news for you.
The Timewalking NPCs that sell Heirloom upgrade tokens spawn only duringTimewalking events and thus will be unavailable until January 3, 2022, when the first Timewalking event of Dragonflight happens.
Until then, you can only buy Heirloom upgrade tokens with gold. The Alliance vendor is Krom Stoutarm and can be found in Ironforge’s Hall of Explorers. The Horde vendor is Estelle Gendry and can be found at the Orgrimmar entrance gates.
