Principality Fusion Calculator - Persona 5 Royal

Forward fusion

Fusion from Principality

Use forward fusion when Principality is already in your compendium and you want to know what it can become. This is especially helpful when building chains toward late-game Persona such as Lucifer, Michael, Satanael, Seth, or Trumpeter.

The Principality fusion calculator is useful in both directions. Reverse fusion tells you how to create Principality. Forward fusion tells you whether Principality can become a stronger Persona, a special-fusion ingredient, or a stepping stone toward a skill route. Use both tables before spending compendium yen.

Skills and itemization

Principality skills and itemization

Skill levels marked 0 are available at base level. Itemization can differ during a Fusion Alarm, so check both the normal item and alarm item before sacrificing a Persona.

Route notes

How to plan a Principality fusion

Principality is a level 29 Justice Persona with Bless inheritance and the Blessed Bloodline trait. Those facts are more useful together than in isolation: inheritance limits which skills can travel into the result, while the trait can decide whether a recipe fits a damage, support, or defensive build.

For a standard fusion, start with the reverse-fusion table and compare more than one valid pair. A slightly more expensive recipe can be better when it reuses a registered Persona, preserves a desired skill source, or avoids a DLC-dependent result.

Recipe planning

Principality fusion calculator planning guide

The Principality fusion calculator is designed for players who want a specific Persona rather than a broad Arcana result. Start with the reverse fusion table when your goal is to make Principality as directly as possible. Sort mentally by cost, ingredient availability, and whether either ingredient already exists in your compendium. The cheapest listed recipe is not always the best recipe if another pair saves time or carries better skills.

The Principality fusion calculator also helps when a recipe result looks wrong in-game. If Principality is not appearing, check whether your DLC settings match your save file. DLC Persona can change the next valid result inside an Arcana range. If a Treasure Demon appears in the recipe, remember that rare fusion can depend on the other Persona's current rank or level position.

If Principality is marked as special fusion, the Principality fusion calculator should be read differently. Special Persona do not come from normal two-Persona Arcana math. They require fixed ingredients, and those ingredients may need their own routes. Open each ingredient page, build the chain backward, then return to Principality when all required pieces are ready.

If Principality is part of a larger build, use this page beside the Persona 5 Royal Skill List. A recipe that creates Principality may not carry the passive, attack, healing skill, or support skill you want. Search the skill first, identify possible source Persona, then compare whether those sources can connect into a Principality fusion route.

If you plan to itemize Principality, check the itemization section before following a long route. Some Persona have a normal item and a separate Fusion Alarm item. The Principality fusion calculator gives the recipe context, while the Fusion Alarm page helps decide whether the item result is worth the cost of creating Principality.
