The Timewalking Mage Tower Challenges may be the same as those that players experienced in Legion, but the rewards will be different. When the Mage Tower closed at the end of Legion, it was firmly established that those rewards would become unavailable. Many players pushed themselves to collect all the appearances they could before the tower closed. Reintroducing those same appearances now would diminish those players’ accomplishment
