I still continue to test until Nidhogg arrives, although the current situation is bad.

For now, Christmas Dusty Miller is a competent hitter, and the bonus attack bonus is similar (Lv80=Kerria-146% attack. Boss 15%,Lv70=Miller-143%, 15%) only differs from Kerria by about 20,000 damage (every round of combat Skill but does not include critical strikes)
