Without Awakening I on Fior, you’re probably not consistently killing both adds on the first break if you follow this setup. Instead, I would recommend making the following changes to the first few turns:
T1: Fior Collapse Charge on the right add
T2: Fior Sanrendan on the left add
T3: Primrose teamwide buff, Fior Round Dual, Gertrude Guillotine on Glossom (basically you stall an extra turn to get a better setup)
T5: kill both adds
The fight becomes 9 turns as a result, but that’s still quite fast and very doable for grinding out Glossom guidestones.
