How to Use Persona 5 Royal Fusion Calculator
The Persona 5 Royal Fusion Calculator puts two powerful modes at your fingertips. Switch between Forward Fusion and Reverse Fusion using the tab bar at the top of the tool.
Forward Fusion:
- Search for Persona A — type part of the name or arcana to find it in the dropdown.
- Search for Persona B — repeat for the second ingredient.
- Read the result — the Persona 5 Royal Fusion Calculator shows the base level, predicted result arcana, and the specific Persona you would receive in the Velvet Room.
Reverse Fusion:
- Search for your target Persona — the Persona you want to create.
- Optionally set filters — restrict by arcana, minimum level, or maximum level to shorten the list.
- Browse ingredient pairs — the Persona 5 Royal Fusion Calculator lists every pair of non-special Personas whose fused level matches the target.
Use the DLC toggle to include or exclude downloadable content Personas, and enable Royal Exclusive to focus on Personas added in the Royal edition.
Formula & Theory - Persona 5 Royal Fusion Calculator
The Persona 5 Royal Fusion Calculator applies the standard two-Persona fusion formula used in the Velvet Room:
base_level = floor((level_A + level_B) / 2) + 1
result_persona = lowest-level Persona in result_arcana
with level >= base_level| Symbol | Meaning |
|---|---|
level_A | Level of the first ingredient Persona |
level_B | Level of the second ingredient Persona |
base_level | Minimum level the result Persona must reach |
result_arcana | Arcana determined by the P5R arcana combination chart |
Arcana combination rules:
- Fool arcana fusions follow the exact tarot-pairing swap rule (e.g., Fool + Magician always yields a Justice-arcana Persona).
- Non-Fool combinations are estimated by a deterministic approximation. Always confirm the exact result arcana in the in-game Velvet Room or a P5R reference wiki before committing valuable items.
Special Fusions
Some high-tier Personas (marked with a Special badge) require a unique combination of three or more specific Personas and cannot be obtained through normal two-Persona fusion. The Persona 5 Royal Fusion Calculator does not model these special recipes. Check the P5R compendium for full requirements.
DLC and Royal Version Notes
DLC Personas (from Persona 3, 4, and other packs) can be powerful but require purchased content. Royal-exclusive Personas belong to the Faith arcana and are unavailable in the base Persona 5 release. Toggle these options on or off to match your game version.
Use Cases for Persona 5 Royal Fusion Calculator
The Persona 5 Royal Fusion Calculator is useful at every stage of your playthrough:
- Early-game planning — find which low-level Personas combine to reach mid-game staples like Ame-no-Uzume or Unicorn.
- Boss preparation — use Reverse mode to identify the easiest ingredient pair for a high-level result Persona with useful resistances.
- Compendium completion — systematically work toward registering every arcana by identifying available ingredient combinations.
- DLC build planning — include or exclude DLC Personas to plan fusions that fit your owned content.
- Min-level routing — filter ingredient levels in Reverse mode to ensure you only use Personas you already own without over-leveling.
Use the Persona 5 Royal Fusion Calculator alongside the in-game Velvet Room to validate results and fine-tune your Persona build before spending rare materials or expensive Persona registrations.
