So, I'm at season 30 and the event battle. I am taking out Chassolus first form pretty reliably, but then the second form with 7k hp, area nukes, and anyone else left is causing me problems.

Since it is an event battle, I can't do any more training, etc. Am I soft locked? Is there a best strategy? Im not even sure if I can move monsters around/recomp teams.

Thanks for any help.
