hey yall, ive just been wondering since there's like

0 guides or anything whatsoever on how to actually beat this boss, specifically the third phase of it with the ordeals and such. And even more specifically the amber midnight mass attack since no matter what I do atleast SOMEONE is staggered before or after it and it frustrates me to no end

so if anyone can just give any advice at all for the third phase that would be amazing,thanks
