Hey y'all! Hope everyone's having a nice night/day, just have a quick question.

So I recently got into the caves and ended up summoning Dia. While I'm able to defeat all of the mini bosses, Dia knocks me out pretty fast. I'm able to get through her first summoning without an issue, but when she begins the second all of my pets suddenly lose all of their health(??) I don't exactly understand why this is happening as I'm using ice sphere with my water pet. I also struggle with killing her disiples before nine turns is up.

Maybe I'm missing something though?

If it's any help, all of my pets have +1 vinethorn gear and are max/super stats. I run a water/light/air party and they've been pretty capable until now. . .

Any help would be appreciated!! :)
