I guess team one is for top path and team two for bottom?
I RGed Aeonium just for that stage but I didn't get good results yet. Stoke Aster is good too so, she is still worth it but not that much for that specific battle.
And just, why a +pierce FM on the second team? You have 2 pierce and Tampala cover the last 3 with her ability.
Edit: Did it. I barely managed to finish after Adlay resurection but it worked. That surprise priority at mid life is a real pain. Thanks a lot.
I really wonder how you got the teams ideas. I tried some classic stuff and nothing worked at all.
Also, I'm glad I could use Kerria again. I never used her since the huge ability rework.
