Oberon Fusion Calculator - Persona 5 Royal

Forward fusion

Fusion from Oberon

Use forward fusion when Oberon 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 Oberon fusion calculator is useful in both directions. Reverse fusion tells you how to create Oberon. Forward fusion tells you whether Oberon 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

Oberon 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 Oberon fusion

Oberon is a level 66 Emperor Persona with Electric inheritance and the Static Electricity 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

Oberon fusion calculator planning guide

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

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

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