The Mage Tower is available again in Patch 10.0.5, so we’re looking at all the rewards you can unlock!
1. Guardian Druid Bear Form
Guardian Druids can get a fel-themed Bear Form after completing the tank challenge. This is a recolor of the White Bear Form from the Legion Artifact that was removed. All Druids on your account will have access to this form once unlocked.
2. Soaring Spell Tome Mount
You will receive the Mage-Bound Spelltome mount from the A Tour of Towers achievement, which requires you to complete every unique challenge available at the Mage Tower.
In the forgotten depths of the Dalaran library, this oversized tome was found flapping madly around the room. Open the pages of this arcane-infused book and hitch a ride to magical adventure.
The character stands on the book while riding the mount.
3. Armor Sets
The Mage Tower Sets are recolors of Mythic Tomb of Sargeras Tier 20 sets. Every class has a different set that you can check out below. Some classes have two variations due to multiple chest armor pieces. I’m not sure if Evokers get a unique set as I don’t main one.
Death Knight
Demon Hunter
Druid
Evoker
???
Hunter
Mage
Monk
Paladin
Priest
Rogue
Shaman
Warlock
Warrior
4. Tower Overwhelming Achievement
Tower Overwhelming doesn’t reward anything, but the achievement is quite the challenge for players who must complete every challenge at the Mage Tower across all classes and specializations.
