What is p5 fusion calculator?
A p5 fusion calculator is an essential tool for players of Persona 5 and Persona 5 Royal. In the Velvet Room, Igor and his assistants allow you to fuse two or more Personas to create a more powerful entity. However, the results are not random. They follow strict mathematical rules based on the Arcana of the ingredients and their base levels. Using a p5 fusion calculator allows you to plan your team, ensure you inherit the right skills, and reach the 100% Compendium completion mark without wasting in-game currency (Yen).
Whether you are a newcomer or a veteran, understanding how a p5 fusion calculator works is the difference between a mediocre team and a god-like lineup. It helps you navigate the complex [velvet-room-mechanics](/velvet-room-mechanics) and ensures you are always prepared for the next Palace boss.
p5 fusion calculator Formula and Mathematical Explanation
The core logic behind every p5 fusion calculator relies on two primary factors: the Arcana Combination Table and the Level Calculation Formula. When you fuse two Personas of different Arcanas, the game first determines the resulting Arcana. Then, it calculates the "Target Level" to find the specific Persona within that Arcana.
The Level Formula
The mathematical formula used by the p5 fusion calculator is:
Target Level = floor((Base Level A + Base Level B) / 2) + 1
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Base Level A | The original level of the first Persona | Level | 1 – 99 |
| Base Level B | The original level of the second Persona | Level | 1 – 99 |
| Target Level | The minimum level the result must be | Level | 2 – 100 |
Practical Examples (Real-World Use Cases)
Example 1: Early Game Fusion
Suppose you are using the p5 fusion calculator to fuse Arsene (Fool, Level 1) and Pixie (Lovers, Level 2). The formula would be: (1 + 2) / 2 + 1 = 2.5. The game floors this to 2. The p5 fusion calculator then looks at the resulting Arcana (Fool + Lovers = Chariot) and finds the Chariot Persona with the lowest base level that is equal to or higher than 2. In this case, it would result in Agathion (Level 3).
Example 2: High-Level Optimization
If you fuse a Level 80 Persona with a Level 90 Persona, the p5 fusion calculator predicts a target level of (80+90)/2 + 1 = 86. The tool will then identify the Persona in the resulting Arcana that sits just above level 86, helping you secure endgame powerhouses.
How to Use This p5 fusion calculator
- Select Arcana: Choose the Arcana for both Persona 1 and Persona 2 from the dropdown menus.
- Input Levels: Enter the base levels of your Personas. Note that the p5 fusion calculator uses base levels, not current levels boosted by Gallows or combat.
- Review Results: The tool instantly updates the Target Result Level and the predicted Resulting Arcana.
- Analyze the Chart: Use the visual bar chart to see how the levels scale during the fusion process.
- Copy Data: Use the "Copy Fusion Data" button to save your recipe for later use in your [persona-5-royal-guide](/persona-5-royal-guide).
Key Factors That Affect p5 fusion calculator Results
- Arcana Combinations: Every pair of Arcanas has a fixed result. For example, Fool + Magician always results in Death.
- Base Level vs. Current Level: The p5 fusion calculator strictly uses the base level found in the Compendium.
- Treasure Demons: These special Personas do not follow standard rules; they shift the level of a Persona within its own Arcana.
- DLC Personas: If you have DLC installed, the p5 fusion calculator results may shift because new Personas are inserted into the level hierarchy.
- Special Fusions: Some Personas require 3, 4, or even 6 ingredients and cannot be predicted by a standard two-way p5 fusion calculator.
- Confidant Rank: While it doesn't change the resulting Persona, high ranks provide EXP bursts that increase the level *after* fusion.
Frequently Asked Questions (FAQ)
Yes, the core mathematical formulas remain the same, though the [arcana-chart](/arcana-chart) has slight variations due to new Personas like those of the Faith and Councillor Arcanas.
Check if you are using DLC Personas. DLC adds new entries to the level list, which can "push" the result to a different Persona than a standard p5 fusion calculator predicts.
Fusing two Personas of the same Arcana usually results in a Persona of that same Arcana but at a lower level rank.
Normally, no. However, if you maximize the Strength Confidant, you can pay Yen to fuse Personas above your level, making the p5 fusion calculator even more valuable.
Treasure Demons act as "rank up" or "rank down" modifiers within the same Arcana. They are not standard fusions.
No, skill inheritance only affects the moveset of the resulting Persona, not the Persona itself or its base level.
The +1 in the formula `(L1+L2)/2 + 1` is the standard game logic to ensure the result is generally higher than the average of the parents.
The only limits are your level (unless Strength is maxed), your Yen, and the specific [skill-inheritance-rules](/skill-inheritance-rules) for certain unique moves.
