Blizzard has updated the Creation Catalyst assets in preparation for Dragonflight and the feature will most likely transition over to the new expansion.
The Creation Catalyst acts as bad luck protection for players who were not lucky enough to form their Tier Set yet. For Dragonflight specifically, there will most likely be a currency and you’ll need to Dragonflight Season 1 item to convert it to a Tier Set piece.
Obviously, it won’t be located in Zereth Mortis. The system has not been implemented yet in the Beta and we’ll keep you updated with more details as they become available.
