Made a few mistakes here and there, but I went in mostly blind. Didn't know any of the triggers/ODs etc aside from the 1st stage being a perma debuffer unless you use abilities every single turn.
Had no clue about Tiamat, but still managed to win off-element. I finished up at 13F this time, so just using my spare keys to yolo 14-15 with off element teams hoping to get a few hundred extra medals.

In the end, I finished with 9900 medals!
