The secret boss encounter against Lavenza in Persona 5 Royal represents the ultimate test of strategy, preparation, and tactical awareness for veteran players. Unlocked exclusively during New Game Plus in the third semester, this multi-phase battle punishes minor errors and demands a thorough understanding of combat mechanics. Players must meticulously prepare their team, persona skill sets, and item loadouts to overcome strict phase requirements and strict turn limits.

Essential Team Preparation and Persona Loadouts

Before challenging Lavenza, maxing out party member confidants and unlocking their third-tier Personas is highly recommended. Joker should carry a diverse roster of level 99 Personas equipped with high-tier elemental spells, passives like Enduring Soul, and critical rate boosts. Equipping party members with top-tier gear and accessories that grant vital support skills ensures high survivability across every phase.

Mastering the Four Battle Phases

Lavenza's encounter is split into four distinct phases, each requiring a completely different combat approach to proceed without suffering a party-wiping attack. The first phase tests elemental coverage, requiring players to deal significant damage while exploiting shifting elemental weaknesses. Phase two demands consistent Technical damage, while phase three mandates scoring at least one Critical hit per turn cycle to avoid an immediate defeat screen.

Tactical Management and Consumables

Managing SP and buff statuses is vital during this extended clash. Utilizing items that cast Thermopylae, Debilitate, or high-level healing spells allows party members to maintain offensive pressure without wasting turn economy. Strategic use of Baton Passes amplifies overall damage output, ensuring your party meets the strict health thresholds required to push Lavenza into her final, all-out phase.

Final Phase Execution and Victory Strategy

In the fourth and final phase, Lavenza unleashes powerful physical attacks alongside Megidolaon. Maintaining maximum buffs and applying attack debuffs to Lavenza is essential for surviving her onslaught while outputting consistent damage. By keeping up a steady rhythm of defense and targeted strikes, players can finally triumph over the Velvet Room's most formidable attendant.
