December 3rd: The true culprit is revealed: Tohru Adachi. He will flee into the TV World, creating the 'Magatsu Inaba' dungeon. The deadline for this dungeon is December 22nd.
December 4th - 6th: Explore Magatsu Inaba. This dungeon is a twisted version of Inaba, reflecting Adachi's distorted view. Shadows here are very strong, so ensure your party is at a high level (around level 70-75) and has their ultimate Personas if possible. The dungeon has two main sections: Magatsu Inaba and Magatsu Mandala.
Magatsu Inaba Key Shadows:
- Chaos Fuzz: Weak to Fire.
- Jotun of Grief: Weak to Ice.
- Minotaur IV: Weak to Elec.
December 7th: If you've reached the end of Magatsu Mandala, you'll face the dungeon boss.
Boss: Tohru Adachi & Ameno-sagiri
- Weakness: None.
- Resistances: None.
- Strategy: This is a two-phase boss fight. First, you fight Adachi. He uses various elemental attacks, status ailments, and can inflict 'Mute' and 'Fear'. He also has a powerful Almighty attack called 'Megidolaon'. Focus on strong physical attacks and your best elemental spells. Keep your party healed and use buffs/debuffs. After defeating Adachi, he will summon Ameno-sagiri. Ameno-sagiri has no weaknesses and can absorb various elements. It will use powerful Almighty attacks and can inflict 'Silence' and 'Enervation'. Its most dangerous attack is 'Nebula Opus', which hits all party members for massive Almighty damage. Use Guard when it charges this attack. Focus on consistent damage, healing, and maintaining buffs/debuffs. This is a long and challenging fight.
After defeating Ameno-sagiri, Adachi is defeated. The case appears to be closed, but there's still one more secret to uncover for the true ending.
