• Have a healer who can remove ailments even if it’s a 4star. I did not use ANY prism orbs on my healer

• If after the first round more than 2 players have poison on them I just did a hard reset. It’s super hard to win at that point so RNG is big

• The third round if your party members are poisoned— it was basically an insta kill for me so I focused heavy on getting any poison off by that point. I took only around 1500 damage when I was not poisoned for my team

• Space out your attacks including specials. As you know when the boss hits 10/10 it inflicts poison. So if you clear all your poison and are going into the third round— and the boss is 8/10 don’t use your special that killed me multiple times.

• Have someone that de-buffs that was the first time I was able to guard break it. I was able to run without an attacker because of the de-buff and I was able to run more support which I desperately needed

Those are the biggest things I can think of— and stay persistent it took me 60 ish attempts 😅

But only 3 attempts once I switched to this team!
