What is a Shin Megami Tensei 3 Fusion Calculator?

The shin megami tensei 3 fusion calculator is an essential tool for players of SMT III: Nocturne (and its HD Remaster). Demon fusion is the primary method of acquiring powerful allies in the Vortex World. Unlike traditional RPGs where you level up a single party, SMT rewards players for constantly fusing their current demons into higher-tier entities that inherit powerful skills.

Who should use this? Anyone from beginners struggling with Matador to veterans aiming for a perfect 100% Compendium. A common misconception is that fusion results are random. In reality, fusion follows a strict mathematical logic based on the Base Level and Race of the ingredients. Using a shin megami tensei 3 fusion calculator ensures you don’t waste precious resources or accidentally lose a unique skill during the process.

Shin Megami Tensei 3 Fusion Calculator Formula and Mathematical Explanation

The logic behind the shin megami tensei 3 fusion calculator is consistent across most fusions. The game identifies the resulting demon based on two factors: the resulting Race and the target Level.

Step-by-step derivation:

1. Identify the Resulting Race using the SMT III Fusion Chart.
2. Calculate the Average Base Level of the two parent demons.
3. Add 1 to that average.
4. The result is the lowest-level demon in the Resulting Race that is equal to or higher than the calculated target.

Variables Table

Variable	Meaning	Unit	Typical Range
Lvl 1 / Lvl 2	Base Level of Parents	Levels	1 – 99
Avg Lvl	Arithmetic Mean	Levels	1 – 99
Target Lvl	Final Threshold	Levels	Avg + 1
Race Result	Lookup Outcome	Category	Varies by Chart

Practical Examples (Real-World Use Cases)

Example 1: You want to fuse a Divine race demon. You use a Level 15 Fairy and a Level 20 Beast. The shin megami tensei 3 fusion calculator shows an average level of 17.5. Adding 1 gives us 18.5. The game will look for the first Divine demon at level 19 or higher, likely resulting in an Archangel.

Example 2: High-level fusion. Fusing a Level 60 Genma and a Level 64 Vile. The average is 62. The target level is 63. If the resulting race is Megami, the calculator will point to the specific Megami demon at that tier, such as Lakshmi or Scathach depending on the exact race table values.

How to Use This Shin Megami Tensei 3 Fusion Calculator

1. Select Ingredient Races: Use the dropdown menus to pick the races of your two demons.
2. Input Base Levels: Enter the current base levels. Note: “Base Level” refers to the level the demon starts at, not its current boosted level, though for many standard fusions, current level is used in the calculation.
3. Analyze the Primary Result: Look at the highlighted box to see the likely resulting race.
4. Review Intermediate Values: Check the “Target Level” to see which tier of demon you will hit.
5. Copy for Planning: Use the “Copy Results” button to save your fusion path into a notes app or spreadsheet.

Key Factors That Affect Shin Megami Tensei 3 Fusion Results

• Kagutsuchi Phase: Fusing during a Full Moon (SILENT) or NEW moon can trigger “Fusion Accidents” or allow for Sacrificial Fusion.
• Deathstones: Required for fusing Fiends like Matador or Daisoujou. Our shin megami tensei 3 fusion calculator assumes standard fusion unless specified.
• Sacrificial Fusion: Adding a third demon increases the resulting level and transfers more skills, but it is only available during a Full Kagutsuchi.
• Elemental Fusion: Fusing a demon with an Element (Erthys, Aeros, etc.) will rank the demon up or down within its own race.
• Cursed Fusion: If the protagonist is “Cursed” via a Magatama, fusion results may flip or become inverted.
• Skill Inheritance: The more skills the parents have, the more slots the child can inherit. This is a critical factor in late-game optimization.

Frequently Asked Questions (FAQ)

1. Can I fuse any two demons?

Most demons can be fused, but certain “special fusions” require specific combinations and often specific Kagutsuchi phases.

2. Why didn’t I get the level the calculator predicted?

The shin megami tensei 3 fusion calculator uses base levels. If your demons have gained many levels via grinding, the target level might shift higher.

3. What is a Fusion Accident?

A random occurrence where the result is not what was predicted. The probability increases during a Full Moon.

4. How do I get Mitamas?

Mitamas are created by fusing two Elements together. They are used to boost stats without changing the demon’s race.

5. Do I lose skills when I fuse?

You choose which skills to inherit. Using a shin megami tensei 3 fusion calculator helps you plan which demons have the best skill pools to pass down.

6. Can I fuse a demon higher than my level?

No, the resulting demon’s level cannot exceed the protagonist’s current level unless it’s a special evolution.

7. What are Elements?

Elements (Aeros, Erthys, Flaemis, Aquans) are special demons used to “rank up” or “rank down” a demon within the same race.

8. Is the HD Remaster fusion different?

The math remains the same, but the Remaster allows you to manually select skills, making the shin megami tensei 3 fusion calculator even more powerful for planning.
