Persona 5: The Phantom X Justine & Caroline
Persona 5: The Phantom X Justine & Caroline Full Kit Breakdown
Let’s get started with this Persona 5: The Phantom X Justine & Caroline build guide to consider if they're worth it or not by looking into their full kit. Before battle, you can choose two out of four Persona pairs for Justine & Caroline. For example, pairing Mischief with Absurdity creates the Strategist setup. Their first and second skills generate "Facades," which are like appearances or buffs, while their third skill can consume two or more Facades to trigger combo effects. Each Persona pair also has a highlight ability that comes off a 30-second cooldown.

All their skills get stronger with Desire Level. You gain one stack for every 100 ATK, up to 15 stacks. Damage multiplier increases by 2% per stack, up to 5 stacks, and critical damage goes up by 6% for every 100% over base, also up to 5 stacks

Awareness Priorities for Justine & Caroline
You can start with skills that give the biggest impact. Their first awareness, Reluctant Tolerance, begins with two Facades and lets S3 trigger automatically every turn, which can really turn the tide in battles. Awareness A0 gives a +25 Desire start and boosts Wonder’s skill by one level. A4 makes highlight abilities even stronger, giving +40% ATK and +20% damage for two turns, with 50% of that bonus also applying to allies.
Other awareness levels, like A2, A3, and A5, increase buffs or raise skill levels by two. A6 adds another Wonder boost, +20 Desire, and makes True Desire take S3 damage to an extremely high level.

Best Teams & Persona Choices
Role (Best) | Personas (5★/4★/3★) | Team | Playstyle |
Strategist (S+ Buffer) | Bishamonten/Dominion/Dionysus | Twins / Queen / Vino / Phoebe | Buff ATK/DMG/Crit for Nuclear burst. Rot: S1 > S2 > S3. |
Assassin (A DPS) | Sandalphon/Vishnu/Dionysus | Twins / Chord / Vino / Oracle | ST Almighty + Crit amp. |
Medic (A Sustain) | Dominion/Surt/Dionysus | Twins / S. Closer / Marian / Oracle | Heal + Bless DPS. |

Playstyle and Rotations for Justine & Caroline
Make sure to start by choosing Persona pairs that fit the role you want, like Mischief and Absurdity for a Strategist setup. For your rotation with A0 awareness, on the first turn use S1 to generate the first Facade, then S2 on the second turn for the second Facade, and S3 on the third turn to trigger a combo. Keep repeating this pattern while using Highlights whenever they’re ready.
Playstyle and Rotations
Once you unlock A1 or higher, S3 will activate automatically every turn. You can swap to skills like Thief Tactics to maintain energy efficiently. Place Justine & Caroline in the frontline when you need buffs, then consider swapping them out after using S3. Prioritize SPD as a substat to get more turns, and remember that their Almighty attacks can pierce through boss defenses.
F2P Path: If you’re playing free-to-play, you can get A1 quickly with Nativity Purple and event rewards. Focus on farming the Crossroads of Fate event to collect Ink and Jewels for further upgrades.
Why Justine & Caroline Are Worth Summoning?
The Twins stand out as SS-tier support characters, especially strong in PvE activities like Mementos and boss battles. They fit into almost any team, helping in multiple ways: boosting damage, healing, shielding, or dealing Almighty attacks. Even when they are not on the field, they passively enhance Wonder’s Persona skills by one level at A0, adding extra value to your squad and that is why most players consider summoning them to their gameplay
Justine & Caroline Summoning
Pros | Cons |
Switch between 6 roles (Strategist, Assassin, Sweeper, Medic, Guardian, Saboteur) pre-battle via Persona pairs. | Not the absolute best in any single role—specialists like Chord (top Strategist) or Marian (elite Medic) edge them out. |
Scales massively with "Desire Level" (from ATK/DMG/Crit stats), amplifying all skills up to +25 stacks at battle start. | High investment needed for max Desire Level (4500+ ATK, 30%+ DMG Multi, 190%+ Crit DMG). |
A1 auto-casts their S3 nuke/utility every turn—huge F2P power spike. | Pity is 90 pulls for 5★; sig weapon separate banner. |
Almighty damage ignores weaknesses; buffs Wonder globally. | AoE DPS lags behind dedicated Sweepers like Rin. |
Verdict: They are worth summoning for F2P/mid-game players needing a flex unit to carry early PvE. Skip if you have full SS-tier specialists or prioritize hypercarries like Queen. Aim for A1 minimum as their banner runs until January 15, 2026, with boosted rates. Low on Meta Jewels? Don’t worry because you can top up safely via LootBar for instant pulls without account risks, perfect for hitting pity on this limited banner.
Conclusion
And that is all from our Persona 5: The Phantom X Justine & Caroline build guide. If you are in P5X global, and planning to pull these twins, remember, they're a must for versatile squads as they are elevating Wonder and filling roster holes. Pull if your teams lack flex support; whale for A6 sig. and we hope that this guide equips you to dominate with the Twins!
