Phase 1

 

Weak Bullet highly recommended <--this means someone in your MPA **MUST** HAVE IT

 

Upon spawning in, take down his knees first, left then right. Once he drops to the ground and after finishing them both, you'll be granted with a jumping boost for the remainder of the session you're in. Jump up, and hit his arms covering his abdomen. Break the face behind them, to reveal a platform, of sorts. Behind it is an exposed face, which is orange-ish in color. Hit it until its destroyed, where it will turn more blackish.

 

Move to Magatsu's RIGHT arm first, and destroy the larger face just below the shoulder to reveal another platform. Repeat the same process for this, and destroy the exposed face. Repeat this whole process for Magatsu's left arm.

 

If your group is doing well, you'll just now be getting to the Calamity-Binding Arrows. If you haven't finished the above yet, then prioritize this part first. Use the Arrows to hit the highlighted areas. After 30 shots, he will drop down, in this frozen-like state. Jump down and attack his main face. If you do enough damange, this, too, will open up a platform and another exposed face. Destroy this, and if you haven't finished the aforementioned steps, resume that.

 

If you have destroyed all of these exposed faces, then hit any the remaining faces to finish him off. 

 

Weak Bullet users should have this down over everyone else. Be sure to follow this order exactly.

 

Phase 2 (A.I.S.)

 

(Weak Bullet (All A.I.S. units have it now) mandatory)

 

At 30 minutes past the hour, its time to mount up into an A.I.S. unit and become one with your inner Gundam fan. 

 

You and your MPA now have the objective of finishing off the Magatsu event by killing the final 3 Magatsu. Follow the same order as Phase 1: Knees, Chest, Shoulders and Face. Except this time, after you finish them off, you can continue hitting the Chest.

 

Upon spawning in, a Magatsu will spawn on the far side of the map. The first one, Magatsu Shigan, is most vulnerable to Ranged attacks, so use your HYPER CANNON right away once in range.

 

Follow the same order until the next one drops in, Magatsu Higan. This one has a different vulnerability now: Strike attacks. However, your PP regen is favored most by your primary attack, so charge quickly then move to your sword abilities when you have the chance. 

 

Finally, Magatsu Sai-sama-senpai shows himself. His golden brilliance is a result of a golden shower, but you didn't hear that from me. Sai isn't vulnerable to one over the other like the other two were, so use whichever attacks you prefer. Your cannon should also be done with its cooldown by this point, so feel free to use that however.

 

Remember the order for Sai. If any of his core lights are still lit after a few minutes, Sai will flee, and not only will you get lesser rewards, but you will also miss out on experience. Otherwise, do your best to kill his parts quickly. If you don't know if your group killed him or not, look for the pose (see below). 

 

This is an A.I.S.-only phase, as in, you don't actually do anything yourself here, which to date, is the only of its kind. If you die, you will automatically respawn after 5 seconds. All of the abilities you will need are automatically put onto your palette upon boarding, and will revert back to what you had after the Phase has ended.

 

It should also be noted that the A.I.S. unit here will have the same attacks as as Mining Base 3, but the abilities on the palette will be different.
