This is a test between ATK% and crit damage circlet in case of mistsplitter and blackcliff sword.
please note that atk% gives higher damage in the video. However, in case of Amenoma crit-damage circlet would make more damage,
so we need minimum 2000 total atk and 200% crit damage for Ayaka,
if the weapon can not provide enough ATK then you can use atk% circlet.
