WoW The War Within testing is in full swing, with each week introducing new changes to different systems, classes, and zones. Now, according to the latest Wowhead datamine, The War Within could be introducing a major change to gearing.

On May 14, Wowhead found evidence you’ll be able to upgrade your weapons in the next expansion using the Catalyst. If you’re not familiar with the system, it allows you to upgrade any regular gear piece into a tier piece. The system was first introduced as bad luck protection in Shadowlands to help players struggling to complete their tier sets. It seems like it will be called the Matrix Catalyst in The War Within, and it will be located in Dornogal, the Earthen capital city.
