Crucible of Woe, Sorrow, Sadness, and Agony
I think the Crucible was a very well-received event as were the “seasons” challenge this last year. I think they’d be great combined. Take all 24 fights and put them into one quest where you can bring any champion for only one fight.
Rewards could include one T7 Basic
Here’s my crazy idea for a Carina’s challenge to it. Have one Carina’s challenge for each class. You have to take 24 fights with just Tech or just Mystic, etc, which would require you to go very deep in your roster. Rewards would be that class’s awakening gem and R2-3 gem.
Lastly, make a “Normal” version of the quest where it is 24 paths out, each to one fight so it can serve as a museum and fun place to test different champions against different challenges. Full exploration is some T3 or T4 revives.
