Episode Aigis Fusion Calculator: Mastering Persona Combinations
In the expansive universe of Persona 3 Portable’s Episode Aigis, the fusion system stands as one of the most complex and rewarding mechanics for players to master. This comprehensive guide explores the intricacies of Persona fusion, inheritance mechanics, and strategic team building through detailed explanations, visual demonstrations, and practical examples.
Understanding the Fusion System
The fusion calculator in Episode Aigis serves as an essential tool for players looking to optimize their Persona collection. Unlike simple combination systems, Persona fusion follows specific arcana-based rules, inheritance patterns, and special fusion recipes that require strategic planning to execute effectively.
This guide will break down each component of the fusion system, from basic two-persona fusions to complex multi-persona special fusions, providing you with the knowledge needed to create powerful Personas tailored to your playstyle.
Fusion Mechanics and Principles
Arcana Compatibility
The foundation of Persona fusion lies in the arcana system. Each Persona belongs to a specific arcana, and the compatibility between these arcana determines the resulting Persona’s type and potential.
Fusion Types
Episode Aigis features several fusion types, each with unique rules and outcomes:
Normal Fusion
Combining two Personas of compatible arcana to create a new Persona.
Triangle Fusion
Using three Personas to create a more powerful result with enhanced stats.
Special Fusion
Specific Persona combinations that yield unique, powerful results.
Level and Stat Inheritance
When fusing Personas, the resulting Persona’s level and stats are determined by a complex formula that considers the base Personas’ levels, stats, and arcana relationships.

Stat Inheritance Patterns
When a Persona is created through fusion, it inherits skills from its component Personas. The inheritance follows specific patterns:
| Inheritance Type | Probability | Skill Selection | Strategy |
|---|---|---|---|
| Random Inheritance | 70% | Skills chosen randomly from both parents | Save before fusion to reroll |
| Skill Card Influence | 15% | Higher chance for skills from Personas with skill cards | Use skill cards strategically |
| Arcana Affinity | 10% | Skills matching the resulting Persona’s arcana | Plan fusions around desired skills |
| Fixed Inheritance | 5% | Specific skills always inherited | Check fusion calculators for fixed skills |
Advanced Fusion Strategies
Optimizing Skill Inheritance
Mastering skill inheritance is crucial for creating powerful Personas. Here are advanced strategies for optimizing your fusion results:
Skill Inheritance Priority
Passive Skills
Always prioritize useful passive skills as they provide permanent benefits.
Elemental Coverage
Ensure your Persona has attacks covering multiple enemy weaknesses.
Healing & Support
Include at least one healing or support skill for sustainability.
Inheritance Blocking
Sometimes you want to prevent certain skills from being inherited. Use these techniques:
- Fill skill slots with desired skills before fusion
- Use skill cards to replace unwanted skills
- Fuse Personas with complementary skill sets
- Take advantage of skill type affinities
Fusion Chain Optimization
Creating the ultimate Persona often requires planning multiple fusions in sequence. This “fusion chain” approach allows you to transfer specific skills through intermediate Personas to reach your desired result.
This fusion chain demonstrates how to create a versatile healing Persona with both ice and wind attacks by strategically combining Personas with complementary skills.
Special and Ultimate Fusions
Special Fusion Recipes
Special fusions require specific Persona combinations and often result in powerful, unique Personas not available through normal fusion. These recipes remain constant throughout the game and are essential for completing your Persona compendium.
| Result Persona | Arcana | Required Personas | Special Notes |
|---|---|---|---|
| Thanatos | Death | Orpheus, Messiah | Story progression required |
| Surt | Magician | Decarabia, Orobas, Orthrus | High-level fire skills |
| Black Frost | Fool | Jack Frost, King Frost, Pyro Jack | All ice-based Personas |
| Kohryu | Hierophant | Genbu, Seiryu, Suzaku, Byakko | All four celestial Personas |
| Alice | Death | Nebiros, Belial | High-level dark skills |
Ultimate Persona Fusion
In Episode Aigis, each arcana has an “Ultimate Persona” that represents the pinnacle of that arcana’s power. Fusing these requires specific conditions:
Fusion Requirements
- Max Social Link rank for the corresponding arcana
- Specific Persona combinations (varies by arcana)
- Often requires high-level component Personas
- Some require completion of specific quests
Notable Ultimate Personas
- Messiah – The ultimate Judgement Persona
- Odin – The ultimate Emperor Persona
- Lucifer – The ultimate Star Persona

Fusion Formulas and Calculations
Mathematical Foundation of Persona Fusion
While Persona fusion may seem like an arcane art, it follows specific mathematical formulas that determine the level, stats, and skills of the resulting Persona. Understanding these formulas can help you predict fusion outcomes more accurately.
Level Calculation Formula
Result Level = ⌊(P1 Level + P2 Level) / 2 × Arcana Modifier⌋
Where P1 and P2 are the levels of the component Personas, and the Arcana Modifier ranges from 0.8 to 1.2 based on arcana compatibility.
Stat Inheritance Formula
Stat = ⌊(P1 Stat + P2 Stat) / 2⌋ + Random(0, 5)
Each stat is calculated separately with a small random variance to add unpredictability to the fusion process.
Skill Inheritance Probability
The probability of a specific skill being inherited follows this formula:
P(skill) = Base Chance × Arcana Affinity × Skill Card Bonus
| Factor | Value Range | Description |
|---|---|---|
| Base Chance | 10-30% | Default probability based on skill rarity |
| Arcana Affinity | 0.5-2.0x | Multiplier based on arcana-skill compatibility |
| Skill Card Bonus | 1.0-1.5x | Bonus if component Persona has a skill card |

Frequently Asked Questions
The arcana system is fundamental to Persona fusion. Each Persona belongs to a specific arcana, and the compatibility between these arcana determines the resulting Persona. Some arcana combinations produce specific Personas, while others follow level-based formulas. High compatibility between arcana often results in higher-level Personas with better stat growth potential.
While you can’t directly control skill inheritance, you can influence it through several methods. Using Personas with fewer skills increases the chance of desired skills being inherited. Skill cards can be used to fill slots with wanted skills before fusion. Additionally, some Personas have affinities for certain skill types, making those skills more likely to be inherited when those Personas are used in fusion.
Triangle fusion (using three Personas) typically results in higher-level Personas with better stats compared to normal two-Persona fusions. They also allow for more complex skill inheritance patterns, as skills can be drawn from three sources instead of two. However, triangle fusions require more resources and planning. They’re particularly useful for creating powerful Personas in the mid to late game when you have access to a wider variety of Personas.
Most special fusion recipes are available from the beginning of the game, but require specific Personas that may not be accessible until certain points in the story. Some special fusions are locked behind story progression or social link requirements. Consulting a fusion calculator is the best way to identify when specific special fusions become available and what Personas are required for them.
The most effective way to use a fusion calculator is to work backward from your desired result. Identify the Persona you want to create, then use the calculator’s reverse fusion feature to find all possible combinations. Filter results by Personas you currently own, and look for fusion paths that maximize desired skill inheritance. For complex builds, use the fusion chain feature to plan multiple fusions in sequence to transfer specific skills through intermediate Personas.
Yes, some Personas cannot be created through normal fusion and must be obtained through other means. Story-specific Personas, certain boss Personas, and some special event Personas typically cannot be fused. Additionally, the ultimate Personas for social links often require max rank in that social link before they can be fused. DLC Personas also usually cannot be fused and must be downloaded separately.
The levels of the Personas used in fusion directly impact the level of the resulting Persona. Higher-level component Personas generally produce higher-level results. However, the relationship isn’t always straightforward—arcana compatibility modifiers and specific fusion formulas can affect the final level. In some cases, fusing lower-level Personas with high compatibility can produce better results than fusing higher-level Personas with poor compatibility.
Duplicate Personas can be valuable fusion material, especially if they have different skill sets. You can use them to create Personas with customized skill combinations, or sacrifice them in triangle fusions. Some players keep duplicates with different skill specializations for different situations. Before fusing duplicates, consider registering them in the compendium if they have valuable skill sets you might want to access later.
