Strategy
Phase 1: Kill each Apostles During this Phase, the Bloody Moon will do: To move on to Phase 2, you must kill one Apostle of each element. To be technically correct, phase transition happens when the Dark and Light Apostles are dead, so it's possible to have a lingering Apostle of a different element and still transition.
 * New Moon, Half Moon, Full Moon and Crescent Moon rotation
 * Use Meteor Moon every 3 Turns
 * Use remaining actions as normal attacks with 15% chance of them being Comet Moon

Phase 2: Facing Bloody Moon At the Start of the Phase 2, Bloody Moon will use: There is one Threshold at every 20% HP step where it will use Moon Revolt which has a procedural RNG check to use one of these skills (checks for first one, if it fails go to second and so on, until the guaranteed hit if all fails): There are retaliation skills when the Bloody Moon is hit with Black Magic or an item. To be more specific, the boss will use Crimson Moon Descent, Fly to the Moon, Crazy Day or Total Eclipse in retaliation depending on the Moon Phase it currently is (phase -> skill relationship on the section below).
 * Scorn of the Moon, Inflict death (100%) to all enemies, and start a new Moon Rotation cycle, now using the Crimson skill set
 * It will start summoning an Apostle per turn when dropped below 90% HP
 * 20% Chance for Snort -> 20% Chance for 500% Physical -> 20% Chance for -75% Fullbreak -> 10% AoE Death -> 100% Chance for 500% Magical
 * If you hit it with Black Magic and cross a threshold at the same turn, it will retaliate twice, once with the Moon Revolt check, then with the Moon Phase skill.
 * Bloody Moon will still use Meteor Moon every 3 turns and if you cross a threshold during one of those turns, it will still cast it after the threshold retaliation.
 * If you kill Bloody Moon while leaving Apostles alive, they'll go berserk, reviving other Apostles until there are 3 and they'll all cast Kidnap, permanently removing 3 units of yours.
 * If you kill all the Apostles while leaving Bloody Moon alive, an Apostle will be revived on each of the following turns until there are 3 beside the Bloody Moon.

Moon Phases Retaliation Skills These are the skills used in retaliation to Black Magic/Item usage against the Moon: Unlike previously thought, Moon Phases are irrelevant when crossing 20% HP thresholds. You only face the RNG roll specified on the section above.
 * Crimson New Moon: 700% Phys AoE Nuke
 * Crimson Half Moon: AoE -50% ATK/DEF/MAG/SPR for 3 turns
 * Crimson Full Moon: 300% Magic AoE
 * Crimson Crescent Moon: Snort [ST Remove From Battle (100% Chance) for 4 turns]

Tips

 * See testimonials and discussions.
 * Most of the attacks are magic. Gear your team with SPR and keep SPR buff up is highly recommended.
 * The boss can be charmed. Units that can inflict charm can take advantage from it.
 * Mystea's Triteleia Wall is well suited for this fight to tank the MAG damage for your whole team with a chance of surviving by the turn's end. A provoke or full cover tank is still suggested for the physical attacks if your units don't have enough DEF.
 * The esper Leviathan is useful for M Spirit Killer. Ramuh is also useful for M Demon Killer.
 * Units like Ashe or Trance Terra for their AoE non-elemental magic damage will allow for the Apostles to more easily be killed around the same time.
