Same here. With my Kerria team, I'm arround 200k damage usually (turn one, with Maid Cowslip it will increase after but with event pests I never do more than one turn).
My best damages are with the RRose Crit team. If RRose and Easter Helenium act twice, I can reach 1.2M or 1.4M damages. But it's rare. UsuallyI'm more arround 600-700k too.
