Reverse fusion

How to fuse Seth in Persona 5 Royal

The table below is calculated in the browser from Royal fusion rules and your DLC settings. If Seth is a special fusion, the fixed ingredients appear first.

Forward fusion

Fusion from Seth

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

Recipe planning

Seth fusion calculator planning guide

The Seth 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 Seth 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 Seth fusion calculator also helps when a recipe result looks wrong in-game. If Seth 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 Seth is marked as special fusion, the Seth 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 Seth when all required pieces are ready.

If Seth is part of a larger build, use this page beside the Persona 5 Royal Skill List. A recipe that creates Seth 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 Seth fusion route.

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

How to choose a recipe

Use the Seth fusion calculator table as a shortlist. Favor recipes with ingredients you already have, ingredients that learn useful skills, or ingredients that are easy to remake. Be cautious with Treasure Demon recipes because current-level behavior can shift the result.

For strict routes, write down three things: the target Persona, the source Persona that carries your desired skill, and the final recipe that creates Seth. This keeps the route clear when several valid recipes appear.

FAQ

Seth fusion calculator FAQ

What does the Seth fusion calculator show?

The Seth fusion calculator shows reverse fusion recipes, forward fusion results, base stats, skills, itemization, and flags such as DLC, special fusion, Treasure Demon, or max confidant requirements.

Why does a Seth recipe differ from my Persona 5 Royal save?

The most common causes are DLC settings, Treasure Demon rank shifts, current Persona levels, or special fusion requirements. Match the calculator settings to your save before choosing a route.

Should I use the cheapest Seth recipe?

Not always. The cheapest recipe can be good for compendium completion, but a slightly more expensive route may preserve a better skill source or use ingredients you already own.
