I'm 3 turning (with some rng for face cards) the petal nodes using Arash (MLB Imaginary) Lalter (Kaleid) Penth (Damage CE) and the harry Potter MC + support Waver and two fillers with drop CE.
Since the fights are fast, i end upon farming more petals per hour this way than if i was using full drop CE. and i have a lot of apples.
