Completing the Strength Confidant progression with Caroline and Justine in Persona 5 Royal requires players to fuse specific Personas with designated abilities. Reaching Rank 7 demands fusing Lachesis while ensuring it inherits the defensive support skill Tetraja. While the fusion system offers multiple paths, DLC Persona additions and level shifts can sometimes complicate standard recipes for players.

Understanding the Rank 7 Requirements

Caroline and Justine challenge Joker to present a Lachesis carrying Tetraja to unlock further Velvet Room privileges. Tetraja is an essential defensive skill that creates a barrier protecting party members from instant-kill Curse or Bless attacks. Successfully delivering this Persona advances the Strength Arcana and prepares players for higher-tier fusions.

Optimal Fusion Pathways for Lachesis

One reliable method involves fusing Principality, which naturally possesses or learns Tetraja, with Sandman to yield Thoth. Players can then fuse Thoth with Anzu to create Lachesis while passing Tetraja down through the fusion chain. Alternatively, players can fuse Clotho, who learns Tetraja at level 28, with a Stone of Scone to directly obtain Lachesis.

Alternative Methods and Skill Cards

If standard fusion chains feel overwhelming or DLC options alter your outcomes, skill cards offer a convenient shortcut. Participating in specific Velvet Room hangouts or itemizing specific Personas can award a Tetraja skill card. Applying this skill card directly onto any newly fused Lachesis instantly fulfills the twins' request without complex multi-step fusions.

Tips for Managing Velvet Room Progression

Always inspect inherited skills before finalizing any Persona fusion to ensure Tetraja is selected in the transfer menu. Keeping your Persona Compendium updated allows you to easily retrieve base ingredients like Principality or Sandman whenever needed. Advancing the Strength Confidant early grants critical gameplay advantages, including special fusion permissions above Joker's current level.
