Persona 5 Phantom X Best Bui (Yui) Build Guide (March 2026)

Want to unleash devastating electric follow-up attacks that can obliterate enemies in seconds? Bui (Yui) is one of the top-tier Assassins in Persona 5: The Phantom X, and her build is optimized to respond to Part Member multi-attacks with powerful follow-ups that will shock and destroy the enemies.
After extensive testing across multiple game modes and team compositions, I’ve discovered the exact build that transforms this Virtual Phantom Idol into an unstoppable force. Whether you’re a new player who just pulled Yui or a veteran looking to optimize her damage output, this comprehensive guide will show you exactly how to maximize her potential.
Bui (Yui) Overview – Persona 5 Phantom X
Bui’s entire playstyle revolves doing Follow-Up Attacks. She works well with members that have multi-hit attacks, synergizes with Electric teams. She has innate high crit rate and crit damage, but she is very reliant on her assigned “Player 2” dealing damage as well.

| Role | Electric Assassin |
| Persona | Apseudes |
| Specialty | Follow-Up Attacks & Critical Damage |

Why Bui is Top-Tier in Persona 5 Phantom X?
Her core mechanic is called ‘Jolly Cooperation,’ a passive that increases the chances for Yui executing a follow-up attack on enemies, and also buffs allies’ damage and critical chances. Unlike other DPS characters who rely solely on their own actions, Bui creates a multiplicative damage effect by turning every ally’s attack into an opportunity for additional damage.

Best Weapons for Bui in Persona 5 Phantom X
5-Star: Cyber Jammers (Optimal)
Cyber Jammers are the ideal 5-Star weapons for Yui, which increase critical rate by 18.1%, and also increase follow-up damage by 26%. When a follow-up is activated by an ally with the Player 2 buff, or by an ally dealing Electric Damage with a skill, it increases the follow-up attack by an extra 26%.
How to Obtain: Weapon Gacha with Platinum Milicoins
4-Star: Meta Directors (F2P Alternative)
The Meta Directors, with their Refactor perk, increase critical rate by 7.3%, and when performing a follow-up attack increase Electric damage by 9.7% for one turn. This buff can stack up to two times.
How to Obtain: 10 Gecko Coins in the Airsoft Shop
Best Revelation Cards for Bui
Primary Build: Completion & Trust
The Completion Revelation Cards set has a base 10% increment on Electric damage, and the full set adds a potential 27% extra Electric damage (9% granted each time Yui attacks with an Electric skill, stacks 3 times). The total of 37% extra Electric damage is ideal for empowering Bui’s already powerful skills.
Why This Works: Since she is a team player, the Trust Mind Card perk is ideal for her kit, since it will increase the Party’s Electric damage by 12% when 3 Electric damage buffs are active.
Alternative Build: Power & Growth
The Power and Growth combo is a staple for most of the characters in Persona 5: The Phantom X, since it increases damage by 12%, and will keep increasing damage by 10% extra every 6 turns, up to a maximum of 30%.
When to Use: Best for longer battles where the stacking damage buff has time to reach maximum effectiveness.
Budget Option: Completion & Growth
The Completion and Growth Card Set is the best fit for Bui. The set buffs Electric Damage and the crit damage of follow-up attacks.
Persona 5 Phantom X: Best Team Compositions
Team 1: Electric Synergy (Optimal)
Lineup: Bui + Closer + Wonder (Electric Personas) + Riddle/Okyann
Bui is best paired with Closer since they can take advantage of each others skills. Both of them can increase Electric Damage, inflict Shock, and deal bonus damage against Shocked enemies.
Strategy:
- Closer applies Shock consistently with her multi-hit attacks
- Bui capitalizes on Shocked enemies for increased damage
- Wonder provides Electric buffs with Thor or Ame-No-Uzume
- Riddle/Okyann enhance elemental damage
Team 2: Extra Turn Exploitation
Lineup: Bui + Joker + Riddle + Wonder (Healer)
Bui unleashes more follow-up attacks if you team her up with Joker due to his Extra Turn. Use Bui’s Highlight or designate Joker as Player 2 with Sparky Surprise to make good use of Joker’s Extra Turn.
Strategy:
- Designate Joker as Player 2 for guaranteed follow-ups
- Take advantage of having 2 DPS characters, Joker and Bui, by bringing a party-wide buffer like Riddle.
- Wonder focuses on healing/support role
Team 3: F2P Friendly Option
Lineup: Bui + Skull + Leon + Wonder
Strategy:
- Skull provides consistent Electric damage
- Leon buffs with Power of Friendship
- Budget-friendly but still effective
- Wonder fills flex role based on needs
Skill Priority & Leveling Guide
Prioritize leveling up Thief Tactics and Sparky Surprise in order to increase the damage of her follow-up attacks.
- Thief Tactics (Highlight) – Maximum follow-up damage
- Sparky Surprise – Core skill for Player 2 mechanic
- Electric Bomb – If you have enough resources, spare some to level up Electric Bomb to increase the chances of Bui to inflict Shock.
- Meta Dynamite – AoE option for mob clearing
How to Play Bui Effectively
Follow-Up Attack Mechanics
Due to Jolly Cooperation, Bui has an 80% chance to do a follow-up whenever an ally uses a skill to attack an enemy.
Three Ways to Trigger Follow-Ups:
- Passive Chance: 80% chance when allies use skills
- Player 2 Guarantee: When Bui uses Sparky Surprise to designate an ally as Player 2, she is guaranteed to do a follow-up attack after that character uses a skill to deal damage.
- Highlight Mode: Use her Highlight and, for 2 whole turns, she will do follow-up attacks whenever an ally deals damage with a Persona skill!

Frequently Asked Questions
Is Bui worth pulling for F2P players?
Absolutely! While she requires some practice, her damage ceiling is among the highest in the game. She works well even at A0 with F2P equipment options.
What makes Bui different from other Assassins?
Most of BUI’s damage is from her Follow-Up Attacks, making her unique among assassins who typically rely on their own actions.
Can Bui work without Electric teammates?
Yes, but her damage potential is significantly reduced. The Shock synergy and Electric damage buffs from teammates are crucial for optimization.
When should I use Highlight vs Sparky Surprise?
Use Sparky Surprise for sustained damage with specific allies (like Joker). Save Highlight for burst phases or when facing multiple enemies.
Is A1 Bui a significant upgrade?
If you have A1 YUI then you should use Crit Mult. star card and no longer need to build Crit Rate. This allows for more flexible gear choices.
How does Bui compare to other Electric DPS?
She offers the highest damage potential in Electric teams but requires more setup than straightforward DPS like Skull.
What’s the minimum investment for viable Bui?
A0 Bui with 4-star weapon and basic Revelation cards can clear all current content with proper team support.
Conclusion
Bui represents one of the most rewarding characters to master in Persona 5: The Phantom X. Pairing her with Closer can yield great results, and Yui’s passive ‘Jolly Cooperation,’ can be triggered quite often, resulting in powerful chained combos. While she requires more strategic thinking than straightforward DPS characters, the payoff is immense – properly built and played Bui can output damage that rivals or exceeds any other character in the game.
Whether you’re running her in an Electric synergy team with Closer or exploiting extra turns with Joker, remember that Bui’s strength lies in teamwork. Focus on building around her unique mechanics, maintain those Shock statuses, and watch as your enemies fall to an endless barrage of critical follow-up attacks.
