Learn how to maximize your chances of finding rare demons, master the art of negotiation, and utilize fusion effectively to fill out your collection and unlock powerful allies.

Understanding the Persona Compendium

The Persona Compendium is an in-game feature that lists all the Personas Joker can obtain. Once a Persona is acquired (either through negotiation or fusion), it is registered in the Compendium. You can then re-summon registered Personas for a fee, which scales with the Persona's level and rarity.

Methods for Persona Acquisition

Negotiation: During battles in Palaces and Mementos, you can initiate negotiations with most enemy shadows. By choosing the correct dialogue options, you can persuade them to join your party.
Fusion: The primary method for obtaining new Personas. By fusing two or more Personas in the Velvet Room, you can create a new, often more powerful, Persona. Skills and stats are inherited based on specific rules.
Story Progression: Certain unique Personas are automatically obtained as you progress through the main story.
DLC: Some Personas are available as downloadable content.

Strategies for Compendium Completion

Prioritize Negotiation: Always attempt to negotiate with new Personas you encounter. This is the only way to add them to the Compendium without fusion. Pay attention to their dialogue options and weaknesses.
Master Fusion: Fusion is key to obtaining Personas that cannot be negotiated or are required for higher-level fusions. Experiment with different combinations and utilize the inheritance system to create Personas with desired skills.
Level Grinding: Some Personas can only be obtained through fusion at specific levels. Be prepared to grind for experience if necessary.
Utilize the Velvet Room: The Velvet Room is your hub for fusion and Persona management. Familiarize yourself with its functions, including the ability to save and load Personas from the Compendium.
Fuse for Specific Skills: When aiming for specific Personas, research the skills they inherit. You can often manipulate skill inheritance by using Personas with desired skills during fusion.
Check the Compendium Regularly: Keep track of which Personas you still need to acquire. The Compendium will show you the level at which a Persona can be fused or negotiated.
Treasure Demons: These rare demons appear in Palaces and Mementos and are crucial for completing the Compendium. They often have specific weaknesses that should be exploited.

Tips for Efficient Fusion

Save Before Fusing: Always save your game before attempting complex fusions, especially if you're aiming for specific skill inheritance.
Use Lower-Level Personas: Fuse lower-level Personas together to create higher-level ones. This is often more efficient than trying to level up individual high-level Personas.
Understand Skill Inheritance: Certain skills have a higher chance of being inherited than others. Researching this can save you a lot of time and effort.
