Persona 5 Royal Fusion Calculator Formula

The Fusion Calculator utilizes two primary components: determining the resulting Persona’s minimum Level and its new Arcana based on the parents. This simplifies the complex in-game mechanics for quick reference.

Level Result (L_R) = $\lfloor (\frac{L1 + L2}{2}) + 1 \rfloor$ (Min Level)
Arcana Result (A_R) = $MOD((A1 + A2), 22) + 1$ (Arcana Rank)

Variables

The calculation requires four key numerical inputs:

  • Parent Persona 1 Level (L1): The current level of the first Persona.
  • Parent Persona 2 Level (L2): The current level of the second Persona.
  • Parent Persona 1 Arcana Rank (A1): The numerical rank of the first Arcana (e.g., Fool=1, Magician=2, etc., up to Judgement/World=22).
  • Parent Persona 2 Arcana Rank (A2): The numerical rank of the second Arcana.

What is Persona 5 Royal Fusion Calculator?

The Persona 5 Royal Fusion Calculator is an essential tool for players managing their roster in the Velvet Room. Persona fusion is the core mechanic used to create stronger Personas by combining existing ones. The resulting Persona inherits abilities and its strength is heavily influenced by the levels of its components.

While the actual process is complex, involving specific Arcana combinations and inheritance rules, this calculator provides a quick predictive outcome for the resulting level and Arcana type, helping players plan their fusion chains efficiently and strategically.

How to Calculate Persona 5 Royal Fusion (Example)

Let’s walk through an example using the provided inputs:

  1. Determine Parent Inputs: Persona A (Level 10, Arcana Rank 5) and Persona B (Level 14, Arcana Rank 8).
  2. Calculate Resulting Level ($L_R$): The average of the two levels plus one. $(\frac{10 + 14}{2}) + 1 = 12 + 1 = 13$. The minimum resulting level is 13.
  3. Calculate Arcana Rank ($A_R$): Sum the Arcana ranks and find the modulo 22. $(5 + 8) = 13$. Since $13 \le 22$, the resulting rank is 13 (Hanged Man).
  4. Final Result: The fusion is predicted to yield a minimum Level 13 Persona of the Hanged Man Arcana.

Frequently Asked Questions (FAQ)

What is the maximum level a Persona can reach? Personas can reach a maximum level of 99, but their starting level is determined by the fusion result.

Does Social Link Rank affect fusion? Yes, having a higher Social Link (Confidant) rank for a given Arcana grants a bonus EXP boost to the newly fused Persona, making it start at a level higher than the minimum calculated here.

Can I fuse two Personas of the same Arcana? Generally, fusion requires two different Arcanas. Special fusions, like those involving three or more Personas, follow different, set rules.

Why is the level result rounded down? The in-game mechanics dictate that the base level result is typically the rounded-down average of the parents’ base levels, with a small bonus added.
