Persona 5 Royal - Justine and Caroline Secret Boss Guide

May 8, 2020 Taku Bou Persona 5 Royal 19

Details on the secret boss Justine and Caroline in Persona 5 / Persona 5 Royal. Included are an overview and strategy.

Overview

If a player decides to play through the game in New Game+, they will have the opportunity to fight Justine and Caroline as a secret boss. They become available to fight in the first week of May. However, it is highly recommended to only fight them when highly levelled and well equipped. Even with using strong personas such as Satan, Shiva, or Ishtar, the twin wardens can be very difficult to take down.

Unlike other fights, Justine and Caroline have Baton Pass. This can make them remarkably difficult to deal with, as the attack boost they receive after knocking a party member down can be devastating. In addition, should the twins manage to knock down the entire party, they will preform an all-out attack to instantly win the fight.

Strategy

If you want to defeat them, make sure all your teammates are using their awakened persona. This way, they’ll at least have the Evade ability when dealing with their weakness. For the main character, use a persona without any affinity weaknesses or be ready to regularly switch between a number of persona to avoid attacks. The battle has several stages to go through, each stage requiring the player to deal a set amount of total damage to the twins to avoid being instantly killed. Should the player not deal 2700 total damage after five turns have passed, the twins will automatically win the fight.

Also, since they don’t have weaknesses, you’ll have to rely on critical hits. Have at least two healers in the party to prevent taking too much damage. Be sure to work both of the twins down at the same time; should one fall before the other, the remaining warden will revive the other with half health.

Behavior Pattern for Persona 5 Royal

Turns	Justine	Caroline
1 to 5	Triple Down	Vajra Blast
6 to 10	Fire, Ice, Elec, and Wind elemental skills
11 and 15	Single target or Multiple hitting Psy, Nuke, Bless, and Curse skills
16	Triple Down	Vajra Blast
17 and 18	Fire, Ice, Elec, and Wind elemental skills
19 and 20	Single target or Multiple hitting Psy, Nuke, Bless, and Curse skills
21	Supreme Magic Bullet	Spatial Killing
22	Single target or Multiple hitting Fire and Ice skills
23	Single target or Multiple hitting Elec and Wind skills
24	Single target or Multiple hitting Psy and Nuke skills
25	Demonic Decree	Divine Judgment
26	Randomized

The twins cycle between focusing on certain skills and using various elemental attributes depending on the turn. When you reach at least turn 16, the pattern becomes similar to the first turn and will continue to follow the same trend until turn 20. After passing turn 20, the twins will employ new skills and will continue to do so until you reach turn 25. After surpassing turn 25, the twins’ skills become randomized.

Behavior Pattern for Persona 5

1st Stage

Caroline will use Vajra Blasts every so often and Justine will use Triple Down with a high critical rate. If either manages to knock you down, they can cast Dekunda to remove any debuffs the player had applied. For this one, use Trumpeter and cast Debilitate on both the twins. Then, swap to a persona that can nullify physical attacks.

2nd Stage

Here, the twins will begin using a variety of skills. Caroline opens with Maragidyne while Justine will focus on using Garudyne and Ziodyne. However, they’ll retain their Dekunda skills. At some point, one of them will use Diarahan on the another.

3rd Stage

Here, Justine and Caroline will swap to using Frei, Psi, Kouha, and Eiha skills. They’ll use either single or multiple target attacks. Every odd numbered turn, they’ll use Kouha or Eiha. Even numbered turns, they’ll use Psi or Frei.

4th Stage

Here, the twins will keep using the first attacks they used in the same order. They’ll heal each other once they’ve hit half health, but this is the only time that this will happen.

5th Stage

Caroline and Justine are going to start doing a lot more damage from here on. They will each start cycling through attack types. Caroline cycles through physical damage, fire, thunder, psy, and holy. Justine, meanwhile, cycles through gun damage, ice, wind, nuke, and dark.

6th Stage

The final stage. The two wardens will use the same attacks as in the fifth stage in a random order. Try to keep their health as close together as possible to avoid a revival. If you cannot win the game by turn 51, they’ll do an all out attack and end the fight.
