Variables
- R (Resulting Stat): The final calculated value for the new Persona’s attribute (e.g., Agility, Luck).
- A (Base Persona 1 Stat): The core attribute value of the first Persona used in the fusion.
- B (Base Persona 2 Stat): The core attribute value of the second Persona used in the fusion.
- F (Fusion Modifier): A scaling factor, often representing the Arcana bonus, level difference penalties, or special fusion types. Must be a positive number.
What is Persona Fusion Calculator?
A Persona Fusion Calculator is an essential tool for players in the *Persona* and *Shin Megami Tensei* series. It is designed to accurately predict the outcome of fusing two or more Personas (or Demons) to create a new, often more powerful entity.
Our calculator simplifies the process by focusing on a key statistic—such as Strength or Magic—using a robust, generalized formula. This helps users manage resources and ensures the resulting Persona meets their strategic needs before committing valuable in-game resources to the fusion process.
Understanding the fusion mechanics is key to success in high-level play, and this calculator provides a transparent view of how base stats and modifiers interact to produce the final, desired result.
How to Calculate Persona Fusion Calculator (Example)
- Identify Base Stats: Determine the Stat Value (A) for your first Persona (e.g., 70 Strength) and the Stat Value (B) for your second Persona (e.g., 90 Strength).
- Determine Fusion Modifier: Find the relevant Fusion Modifier (F). For example, if you have a rank 8 Arcana bonus, your modifier might be 1.15. (F = 1.15).
- Sum Base Stats: Add the two base stats: $A + B = 70 + 90 = 160$.
- Apply Modifier and Average: Multiply the sum by the Fusion Modifier and divide by two: $\frac{160 \times 1.15}{2} = \frac{184}{2} = 92$.
- Final Result: The resulting Persona’s Strength stat (R) will be 92. Use this value to plan your team composition.
Frequently Asked Questions (FAQ)
The Fusion Modifier (F) scales the average of the base stats. A value greater than 1.0 (e.g., 1.1 or 1.2) represents a bonus, usually from maximizing the corresponding Social Link or Arcana. A value less than 1.0 could represent a penalty or specific fusion conditions.
This calculator is primarily designed for forward calculation. However, algebraically, you can rearrange the formula to solve for A or B: $A = \frac{2R}{F} – B$. Simply use the calculator with the known values to iteratively approximate the missing stat.
While the formula is generalized for any numerical stat, it most accurately models attribute fusion (like HP, SP, Strength, etc.). Level fusion often involves more complex, non-linear progression tables than this simple model.
Errors typically occur if you fail to enter at least three valid numbers, or if the Fusion Modifier (F) is zero or negative. Since F is a scaling factor, it must be a positive value to yield a meaningful, physical result.
