What is a Nocturne Fusion Calculator?
A nocturne fusion calculator is an essential tool for players of Shin Megami Tensei III: Nocturne (and its HD Remaster). Demon fusion is the heart of the game, allowing the protagonist (Demi-fiend) to combine two or more demons to create a more powerful ally. Unlike standard RPGs where you simply level up your party, SMT Nocturne encourages constant turnover, where the nocturne fusion calculator helps predict the outcome of these combinations.
Who should use it? Primarily players looking to optimize their team for boss fights or those aiming to complete the Demon Compendium. A common misconception is that fusion results are random; in reality, they follow a strict mathematical logic based on demon “Races” and “Base Levels.” By using a nocturne fusion calculator, you eliminate the guesswork and ensure your precious Macca isn’t wasted on inefficient fusions.
Nocturne Fusion Calculator Formula and Mathematical Explanation
The math behind the nocturne fusion calculator is consistent across most SMT titles but has specific quirks in Nocturne. The game calculates a “Threshold Level” to determine which demon from the resulting race will appear.
The standard formula used by our nocturne fusion calculator is:
Target Threshold = [(Demon A Base Level + Demon B Base Level) / 2] + 1
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Base Level | The level the demon starts at (Compendium level) | Level | 1 – 95 |
| Current Level | The demon’s level after gaining experience | Level | 1 – 99 |
| Race Modifier | Determines the resulting race of the demon | ID | Varies by Race |
| Sacrifice Level | Additional levels added during a Full Kagutsuchi fusion | EXP | 0 – 1,000,000 |
Practical Examples (Real-World Use Cases)
Let’s look at how the nocturne fusion calculator applies to common in-game scenarios:
Example 1: Early Game Fusion
- Demon A: Pixie (Base Level 2, Current Level 6)
- Demon B: Shikigami (Base Level 4, Current Level 4)
- Calculation: [(2 + 4) / 2] + 1 = 4
- Interpretation: The nocturne fusion calculator shows a threshold of 4. If these two combine into a “Brute” race, you will get the lowest level Brute that is level 4 or higher (likely Momunofu).
Example 2: Late Game Power Fusion
- Demon A: Thor (Base Level 76)
- Demon B: Amaterasu (Base Level 56)
- Calculation: [(76 + 56) / 2] + 1 = 67
- Interpretation: The resulting demon will be the first demon in the target race with a base level of at least 67.
How to Use This Nocturne Fusion Calculator
Using our nocturne fusion calculator is straightforward. Follow these steps to master the Art of Fusion:
- Enter Base Levels: Look up the base levels of your ingredients in the Compendium. This is vital because the game uses base levels, not current levels, to determine the *identity* of the result.
- Input Current Levels: If you have leveled up your demons, enter their current levels to see the “EXP Bonus.” This helps you understand how much stronger the resulting demon will be compared to its stock version.
- Review the Result: The nocturne fusion calculator will display a “Target Threshold.” This is the number you check against race charts to see exactly which demon you’ll get.
- Check Macca Costs: Use the estimated Macca cost to manage your budget, especially if you need to pull demons back from the Compendium.
Key Factors That Affect Nocturne Fusion Calculator Results
- Demon Race: The combination of Race A + Race B determines the Resulting Race. This is the most critical factor before level math even begins.
- Base Levels: As shown by the nocturne fusion calculator, the starting levels of the ingredients are the primary math drivers.
- Kagutsuchi Phase: Fusing during a Full Kagutsuchi allows for “Sacrificial Fusion,” adding a third demon to boost levels significantly.
- Cursed Status: If the Demi-fiend is cursed, certain fusion results may flip, resulting in different races or “Rank Down” fusions.
- Skill Inheritance: While not changing the level, the number of skills on the parents determines how many skills the child inherits.
- Special Recipes: Certain demons (like Fiends) cannot be made via standard level math and require fiend fusion recipes and specific items like Deathstones.
Frequently Asked Questions (FAQ)
Does the current level change who I get?
No. The nocturne fusion calculator logic uses the base level to determine the resulting demon species. Current levels only increase the starting EXP/stats of the result.
How do I calculate Macca costs?
Costs are generally based on the level of the demon being pulled from the Compendium. High-stat demons cost significantly more compendium costs.
What is an Element Fusion?
Fusing a demon with an Element (like Erthys) will result in a “Rank Up” or “Rank Down” within the same race, ignoring the standard nocturne fusion calculator threshold math.
Can I fuse demons higher than my level?
No. You cannot create a demon whose base level is higher than the Demi-fiend’s current level unless you are using specific shinkai skills or special fusion rules.
Where do I find specific demons?
Check our demon fusion guide for a full list of race combinations and locations.
What are Deathstones used for?
They are required for fusing Fiends during specific Kagutsuchi phases. You can find more info on deathstone farming here.
How do Magatamas affect fusion?
Magatamas affect the Demi-fiend’s stats but do not directly change the math in the nocturne fusion calculator. See magatama locations for more.
What is Mitama Fusion?
Mitamas (like Ara Mitama) add bonus stats to an existing demon without changing its race or base level. It’s the ultimate way to polish a team.
