Lavenza can use one attribute at a time.


Purchase an assortment of consumables

By now, you should have hit the cap on the Billiard Rank, attained the powerful magic spells, and invested on Satanael with Gun skills. In addition, you need to collect a couple of consumables for to prepare for the battle. Below is a short summary of items and their locations.

Item Location
Baptism Water Can be bought on Sundays
Super Awakening Air Freshener Second-Hand shop in Kichijoji
Ultimate Disinfection Spray
Moonlight Carrot Gardening
Earth Beans Gardening
Star Dragon Onion Gardening
Sleep Bottle Exchange flowers to Jose
Hustle Supplements Sports Shop
Takeminato Biokir Takemi’s clinic

Assign three different Persona

Apart from items, you need to have three persona. You need to have each of these specialize in one of three roles: support, physical, and almighty attribute. With the exception of the support Persona, train the others to have their attacks and magic capped at 99. Lavenza is a formidable opponent so you need to max out all of your Persona’s levels. A good example would be support Maria, and two damage dealers like Yoshitsune and Satanael. Currently, this section does not cover any of the DLC persona.

Reach Second Awakening

The battle occurs on the third semester which should buy you enough time to awaken your Persona. Having performed awakening guarantees that your roster gets access to all sorts of tools like new skills, higher stats, and resists.

Gear up

Many accessories and equipment provide added skills to fill in the gaps. Below is a list of suitable equipment to use in the fight against Lavenza.

Gear Details
Amrita Spiral Charm Unlocks Amrita Shower
Crystal Skull R Raises all stats by 6 and raises evasion. Best used in the first few phases. Joker can pass it to an ally if his Persona are maxed out.
Extreme Universal Ring Can be given to anyone except Akechi. Allows the holder to use Megidola.
Greedy Ring Best paired with Yusuke. Allows the use of Concentrate.
Orichalcum R Can be given to anyone. Raises all stats by 7 and raises evasion from Phys. Best used in the mid phase.
Seven Ties Best given to Joker or another member that has a similar role. Grants the effect to instantly remove ailments.


The flow of battle depends on the remaining HP of Lavenza. For each phase, you need to bring her HP down by 1/5 to go to the next phase. Simply put, you need to deal a total of 5,000 points of damage to proceed to the next round. Below is a summary of Lavenza’s actions for each phase.

Capitalize on debuffs and almighty attacks

When the battle starts, pair Joker with Akechi. Since Lavenza resists all attributes, you need to play around her with other skills. Combine debuffs like Debilitate with Almighty attacks using Joker and Akechi. Another option is to have Haru use Tetrakarn to reflect incoming attacks while Yusuke and Joker focus on whittling her down.

Phase 1

In Phase 1, there is a 9 turn limit. Lavenza’s health is 5,000 and the goal is to bring it down to 4/5.

Remove ailments

Lavenza’s pattern of attacks depends on the status of its health. In phase 1, she often relies on inflicting ailments. Quickly cure the ailment to avoid taking technical bonus.

Use Almighty skills

Since Lavenza’s attribute will vary, Joker and Akechi can focus on using Megidola for some consistent form of damage.

Phase 2

Inflict an ailment

On the second phase, you will greatly benefit from technical bonus by inflicting Lavenza with ailments. You can obtain those types of items from Jose after exchanging flowers.

Use Persona that blocks Curse

Lavenza starts using Death inflicting skills which can finish you off if it connects on Joker. Avoid it by switching to a Persona that nulls Curse quickly.

Phase 3

In Phase 3, you’ll want to switch to Persona that excel in either Physical or Gun skills. Boost your attacks to land critical hits and use Baton Pass to punish Lavenza.

Aim to score critical hits

Use skills like Swords Dance or One Shot Kill to land those critical effects. Use Baton Pass to strengthen Joker and have your Persona execute Hassou Tobi.

Don’t be afraid to use items

Some items such as the “Hustle Supplement” also increases the chance of getting critical damage. Other than items, you can also switch out a member with Violet and have her use “Bravestep.”

Phase 4

Lavenza turns far stronger than before when her health falls lower than 40%. Don’t take too long to use powerful skills because you’ll incur more damage.

Use almighty attacks

Your best bet is to use Persona with hard-hitting skills. A good example is to use Megidolaon to bring her down.

Combine powerful attacks with critical hits

Similar to Phase 3, Atavaka and Thor can dish out critical hits with Physical skills. You can opt to use Swords Dance or One-Shot Kill.

Focus on attacks and recovery

Although Lavenza can interrupt your chain of attacks with her own, these don’t do enough to knock a member out. Focus solely on offense and combine those with heals.

Determine when to use Guard

Every fifth turn, Lavenza casts a boosted Megidolaon to try and knock your party out. However, depending on your skill set, you might not even need to rely on using Guard on those turns. With passives like Endure, your party should withstand the fatal blow at 1 HP.

  1. almighty skills suck in phase one, also this is a terrible resource. It makes technical hits and critical hits seem optional when it’s life or death. Use anything else but this website

  2. For the Critical Hit phases I used violet and a persona build that you get from fusion accidents with Rebellion, Revolution and the passive skills that amplify critical hits (but those don’t matter because you just need to buff violet). Luckily Izanagi-No-Okami (Picaro and regular) are both extremely hard hitters with Myriad Truths. For this fight you should have a Buffing persona and A really hard hitter, keep in mind Morning star and black viper do quite a bit more damage than Megidolaon, wich all do better than Haussai Tobi

  3. In Phase 4 if Lavenza uses Concentrate & Megidoloan it’s Game Over. I have had Joker guard it at full health and it KO’d and I also tried having Enduring Soul on Satanael and it KO’d me and I didn’t revive. Also I believe it’s in 6 turns, not 5. So you have to finish her off before then. This information is regarding HARD mode.

  4. The third phase is so badly designed, it’s astonishing. You literally just have to hope to christ that you’re lucky enough to get a crit hit. It’s fucking bullshit.

  5. Having trouble actually starting the fight with Lavenza.

    NG+, date is 1/25, I fought and beat the twins (even though it says you do not have to), I cannot talk to her in Mementos. I haven’t found the treasure in the final Palace yet if that matters, and I haven’t fought the special boss in the final zone of mementos. I did just finish Da’at and retract the data cables, but haven’t gone back to the palace yet.

    • I have the same issue. I think you actually have to do some of the Twin events because I didn’t do any of them.

    • She showed up for me on 1/26 after I had secured my infiltration route in the palace. She will stop you as you enter mementos to challenge you and will wait at the door to the Velvet room for you. This is the same day I was able to find ???? at the end of the final path in mementos as well.
      Something of note that this guide does not mention is that if you do not beat her quickly enough (or possibly just do too little damage in a set amount of turns) she will all-out attack you and kill you outright.

    • There is no more twins in 1/25 what are you talking about? They turned into Lavenza in December. Did you hack your game or what?

  6. This guide is wrong.

    Here’s two crucial things you HAVE to know to get through this fight.

    Phase 2 – If you don’t score a technical hit every turn, you die.
    Phase 3 – If you don’t score a crit every turn, you die.

    • How the hell are you supposed to constantly get a crit hit though? Every single time I get to that phase, it’s just fucking impossible.

      • Violet with brave step and swords dance, haru with one-shot kill and Joker with a either one of his choice? Your point still stands though, getting a crit every turn is unreasonable.

        • For that phase I used my Persona who has Critical hit buffs (Revolution And Rebellion) and you can get that build from a fusion accident

      • Agreed, it is unreasonable to get a crit every single turn. Your best bet is probably:

        Violet-Brave step, Apt Pupil and Swords Dance
        Noir-One Shot Kill
        Joker-Apt Pupil and OSK/SD
        Healer/Crow (Crow for debilitate, healer for healer.)

  7. Haw do you stop her insta kill turn 1 of faze 2 she all attacks my team for a insta kill even if my team has full health

  8. This is false information. Lavenza behaves very differently than what the site is stated here. I pair up Ann/Makoto with a break Fire/Nuke and deal more than 1000dmg/hit. After 5 turns she’s switched her stance and let me proceed. But after that turn, she’s just team-wiped me. Happens multiple times, I even try Safe Mode but still get wiped even though I deal almost 2000dmg/hit.
