What is an SMT Fusion Calculator?
An SMT Fusion Calculator is a tool used by players of the Shin Megami Tensei (SMT) series of video games to predict the outcome of demon fusion. Demon fusion is a core mechanic where two or more demons are combined to create a new, often more powerful, demon. This process is not random; it follows a complex set of rules based on the races and base levels of the ingredient demons. This calculator simplifies the process, removing the guesswork and allowing for strategic team planning. Without a reliable smt fusion calculator, players would need to rely on extensive trial-and-error or cumbersome external charts, which can be a significant time investment.
The SMT Fusion Formula and Explanation
Standard two-demon fusion (Dyad Fusion) follows a predictable formula to determine the resulting demon. The process involves two main steps: determining the resultant race and then its base level.
1. Determining the Resultant Race
The race of the resulting demon is determined by a fixed “fusion chart” specific to each game. Fusing a demon of ‘Race A’ with a demon of ‘Race B’ will always result in a demon of ‘Race C’. For example, fusing a Fairy race demon with a Beast race demon might result in a Jirae race demon.
2. Calculating the Resulting Demon
Once the race is determined, the specific demon from that race is found using the following formula:
Resulting Base Level = floor((Base Level of Demon 1 + Base Level of Demon 2) / 2) + 1
The game then looks at the list of demons in the resulting race and picks the first demon whose base level is equal to or higher than the ‘Resulting Base Level’. If no demon is found above the calculated level, it may wrap around or select the highest or lowest demon in the race, depending on the specific SMT game. A good smt fusion calculator accounts for these rules.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Base Level of Demon 1 | The innate starting level of the first demon being fused. | Level | 1 – 99 |
| Base Level of Demon 2 | The innate starting level of the second demon being fused. | Level | 1 – 99 |
| Resulting Race | The race of the new demon, determined by a fusion chart. | Race (e.g., Fairy, Dragon) | N/A |
| Resulting Base Level | The calculated target level for the new demon. | Level | 2 – 100 |
Practical Examples
Example 1: Fusing Two Low-Level Demons
Imagine you want to fuse a Pixie (Fairy, Base Level 2) with a Nekomata (Beast, Base Level 11).
- Inputs: Pixie (Level 2), Nekomata (Level 11)
- Race Fusion: Fairy + Beast = Jirae
- Calculation: `floor((2 + 11) / 2) + 1 = floor(6.5) + 1 = 6 + 1 = 7`
- Result: The calculator would search for the first demon in the ‘Jirae’ race with a base level of 7 or higher. If ‘Sudama’ is a Jirae with base level 17, it might be the result.
Example 2: Fusing a Mid-Level and High-Level Demon
Let’s try fusing an Angel (Divine, Base Level 14) with a Bicorn (Wilder, Base Level 15).
- Inputs: Angel (Level 14), Bicorn (Level 15)
- Race Fusion: Divine + Wilder = Yoma (hypothetically)
- Calculation: `floor((14 + 15) / 2) + 1 = floor(14.5) + 1 = 14 + 1 = 15`
- Result: The calculator finds the first ‘Yoma’ demon at or above level 15. If ‘Apsaras’ is a Yoma with base level 18, she would be the result. Using a smt fusion calculator prevents errors in these multi-step calculations.
How to Use This SMT Fusion Calculator
This tool is designed to be straightforward. Follow these steps to find your desired fusion outcome:
- Select Demon 1: Use the first dropdown menu to choose your first ingredient demon from the list.
- Enter Level for Demon 1: Input the demon’s current level. Note that some game mechanics use base level, while others use current level. This calculator uses base level for simplicity.
- Select Demon 2: Use the second dropdown menu for your second demon.
- Enter Level for Demon 2: Input the second demon’s current level.
- Calculate: Click the “Calculate Fusion” button. The result will appear below, showing the new demon’s name, race, and the calculated level that determined its selection.
- Interpret Results: The primary result is your new demon. The intermediate values show the ‘why’ behind the result, explaining the race and level calculation.
Key Factors That Affect SMT Fusion
- Demon Race: The single most important factor. The combination of races dictates the result’s race.
- Demon Base Level: Determines the rank of the resulting demon within its new race.
- Special Fusions: Certain demons can only be created through a specific, fixed recipe of 2, 3, or even 4 demons. These ignore the standard formula and are a key part of any comprehensive smt fusion calculator.
- Player Level: In most SMT games, you cannot fuse a demon whose base level is higher than your own.
- Moon Phase: Some older SMT titles have fusion accidents or different results based on the phase of the moon.
- Sacrificial Fusions: An extra demon can sometimes be sacrificed to provide an EXP boost to the newly fused demon.
Frequently Asked Questions (FAQ)
What is a Dyad Fusion?
Dyad fusion is the most common type, involving the combination of two demons.
What is a Special Fusion?
A special fusion is a recipe-like fusion that requires specific demons to create a powerful or unique result, bypassing normal fusion rules.
Why can’t I fuse a demon that is a higher level than me?
This is a balancing mechanic in the SMT series to prevent players from acquiring overly powerful demons too early in the game.
What happens during a fusion accident?
A fusion accident is a rare, random event where the fusion fails and produces an unexpected demon, sometimes a rare Slime or Foul race demon.
Does the current level of a demon matter more than its base level?
For standard fusion calculations, the base level is what’s used in the formula. However, the current level can be a factor for skill inheritance.
How does skill inheritance work?
The resulting demon can inherit a certain number of skills from its parent demons. The exact skills are often randomly selected from a pool of inheritable skills.
What is a “reverse fusion” calculator?
A reverse fusion calculator allows you to select a target demon and it will show you all the combinations that can be used to create it. It’s a key feature in advanced tools like this smt fusion calculator.
Are fusion rules the same in all SMT games?
No. While the core concepts are similar, the fusion charts, available demons, and specific rules can vary significantly between games like SMT V, SMT III: Nocturne, and the Persona sub-series.
