Shattering Stars/Summoner

Summoner
Short fight but it's all or nothing. When you enter, use Earthen Ward and Aerial Armor on yourself and get your MP back to full before confronting Maat and drink a Yagudo drink. Bring out whichever avatar is strongest on the current day (or Fenrir if you have him) and immediately use Astral Flow, refill your MP with ethers quickly and use Astral Flow again as soon as it's ready. That should take out Maat. If Maat uses Astral Flow himself, you will not survive. You simply have to be quicker at the draw, nothing more to it.
