I gave it a shot. Had buffs, did it three times, and I won’t be trying that, or any future content with the term Challenge as a part of its description “EVER” again. It just reinforced to me that I am a bad player who shouldn’t be doing any kind of challenging content. So thank you very much development team for leading me to believe that with an overpowered Artifact Weapon, getting the Mage Tower, should be simple to do.
It, and all future content like it, can go burn in the fires of hell.
