Use the same line up and artifact with good stat on sungjiwoo, total power at least 425k (85% from recommended), focus on increase ultimate damage on blessing, i got 100% in total
My basic crit hit damage 180+% and 15+% def penetration. Before ulti using shadow step, light element death dance, min and meilin support skill, amplifier with plum sword then ulti and hope it crit, it will maximize the damage
