How to Unlock Monad Chambers

Complete Colosseo Purgatorio

Persona 3 Reload Episode Aigis - VS Mitsuru and Yukari

Monad Chambers is unlocked a few cutscenes after the completion of Colosseo Purgatorio. Once the player returns to the Abyss of Time to face the final boss, the party will notice another door present within the area.

Monad Chambers Boss List

  1. Immortal Gigas and Visceral Maya
  2. Heat Balance, Sky Balance, and Primitive Idol
  3. El Dorado Beast and Amorous Snake
  4. Brilliant Cyclops and Change Relic

Immortal Gigas and Visceral Maya

Boss Weaknesses and Resistances
Immortal Gigas Weak: N/A
Resists: Wind
Null: Light
Drain: N/A
Repel: Strike, Bash, Pierce
Visceral Maya Weak: Fire
Resists: Ice, Wind
Null: Dark
Drain: Elec
Repel: N/A

A Support + Tank Damage Dealer lineup. The Visceral Maya's roles in this fight is to buff up the Gigas with attack and defense buffs while the Gigas will focus on using physical AoE attacks on your team. Debuffs and multi target attacks are recommended as you'll want to reduce the fight's difficulty by dispatching the Mayas.

Immortal Gigas and Visceral Maya Boss Guide

Heat Balance, Sky Balance, and Primitive Idol

Boss Weaknesses and Resistances
Primitive Idol Weak: N/A
Resists: Fire, Ice, Wind, Elec
Null: N/A
Drain: N/A
Repel: Light, Dark
Sky Balance Weak: Fire, Ice
Resists: Slash
Null: N/A
Drain: N/A
Repel: Elec, Wind
Heat Balance Weak: Elec, Wind
Resists: Slash
Null: N/A
Drain: N/A
Repel: Fire, Ice

We highly recommend bringing individual elemental attacks to target the balance's weaknesses. This can give you additional turns during the fight while slowly whittling down the damage dealer's HP.

It is also useless to counter the Balance's elemental attacks as the Primitive Idol will immediately break your team's resistances to the four elemental types at the start of the fight.

Primitive Idol Boss Guide

El Dorado Beast and Amorous Snake

Boss Weaknesses and Resistances
El Dorado Beast Weak: N/A
Resists: All
Null: N/A
Drain: N/A
Repel: N/A
Amorous Snake Weak: Wind
Resists: Ice
Null: N/A
Drain: Fire
Repel: Light

A battle of attrition where the Amorous Snake will be an easy target but it can use a 2000 HP Life Drain on the El Dorado Beast while the Beast is extremely durable and can regenerate 800 HP per turn passively.

Make sure to always deal 2000 damage to the Amorous Snake every turn to make it drain HP from the beast, otherwise, the beast will be able to regenerate all damage it can take but you also must not deal more than that as you can potentially kill the snake.

Killing the Snake will make the fight near impossible to complete due to the El Dorado Beast's durability.

El Dorado Beast Boss Guide

Brilliant Cyclops and Change Relic

Boss Weaknesses and Resistances
Brilliant Cyclops Weak: N/A
Resists:Strike, Pierce
Null: N/A
Drain: Ice, Elec, Wind
Repel: N/A
Change Relic Weak: Elec
Resists: Fire, Ice
Null: Light, Dark
Drain: N/A
Repel: N/A

The Change Relic is severely weaker in terms of durability than the Cyclops and both will be fighting you with their elemental attacks. However, you must avoid using AoE attacks and killing the Change Relic as doing so will change the Brilliant Cyclops' pattern.

If you kill the Change Relic, the Brilliant Cyclops will start using Concentrate then Megidolaon every turn which can most of your party members in one turn, making the fight more difficult. However, if you can survive, it can be easier to deal with one boss instead of two.

Joker Boss Fight

Joker

Joker is Episode Aigis' super boss and it is arguably the most difficult boss in the entire game, with the base game included. As other Persona protagonists, he's capable of using multiple Personas in combat which will change his resistances while also being capable of dishing out huge amounts of damage per turn.

Is the door not appearing has to do with doing Elizabeth's request? Because this door is not appearing at all 🗿

I've finished the game, went back on the save from the desert but the door is not there. Only the main door for the main boss. Do I need to do anything else?
