All Monad Doors Boss Weaknesses in Persona 3 Reload: Episode Aigis

I love random equipment.

During your Abyss of Time exploration in Persona 3 Reload: Episode Aigis, the Monad Doors can occasionally appear on your current floor. These doors house powerful mini bosses, and defeating them can lead to some great rewards if you’re brave enough to face them.

How to Find the Monad Doors in Persona 3 Reload: Episode Aigis

Similar to the base game, Monad Doors appear randomly in Episode Aigis. However, they’re much more frequent here, and Fuuka will always warn you about a door appearing once you enter a floor. But instead of just a single door, you’ll find three doors in the DLC with three possible mini-bosses each time. Bosses found in Malebolge will be different from those in Cocytus, for example.

The doors are placed from left to right in order of difficulty. You’ll find that the left door will only have a single random mini-boss. The middle door has two of them. The right door has all three possible mini-bosses, fought back-to-back in a single battle. These fights can be lengthy but are very worth the time. They have a boosted chance of dropping Major Arcana Cards during Shuffle Time, and you can get an extra card from it too.

Beating the mini-bosses also gives you the exclusive Monad equipment inside the chests. The harder the battle, the more rewards you get. The left door gives you two random chests, while the right door gives up to eight. I would personally recommended to always go at least for the middle door. Use your Theurgy attacks and exploit your enemy’s weaknesses to secure your victory.

The equipment obtained in the Monad Doors is some of the best available in Episode Aigis, usually outscaling anything from the Police Station and even some rewards from Elizabeth’s Requests. However, they have random passives and the equipment you’re getting is also random. The right door will always give you a weapon, a chest piece, boots and an accessory.

Farming Monad Doors is the perfect way to gear up without spending Yen, as well as grinding some extra levels for the main bosses. It’s also an easy way to get the desired Major Arcana Cards before exploring deeper floors, especially when returning from the dorm.
