終末武器 = 神闇の極 | Opus = Extremity Key

2M hits = MC assassin auto + Deathstrike echo with Orologia 1 = 14 max
Yatima can be everything, I just use her to greed summons and clear some omens easier. Ultima is also whatever you like. You can move however you want, this way of playing is just the best for me and for the room.
