Demon Fusion
What is a Shin Megami Tensei IV Fusion Calculator?
A shin megami tensei iv fusion calculator is a tool used by players of the video game SMT IV to predict the outcome of “demon fusion”. In the game, fusion is a core mechanic where you combine two or more of your allied demons to create a new, typically more powerful, one. This process is not random; it follows a specific set of rules based on the demons’ “Race” and “Base Level”. This calculator automates the process, removing guesswork and allowing players to strategically build their ideal team of demons. It is essential for completing the Demon Compendium and for creating powerful allies with specific skills, a process that can take hours of manual effort.
Anyone playing Shin Megami Tensei IV, from a beginner learning the ropes to a veteran aiming for 100% completion, will find a shin megami tensei iv fusion calculator invaluable. It helps in understanding the deep fusion mechanics and planning fusion paths for powerful demons.
The SMT IV Fusion Formula and Explanation
Standard demon fusion in Shin Megami Tensei IV follows a two-step process. First, the Race of the resulting demon is determined by a fixed chart based on the Races of the two parent demons. Second, the specific demon within that Race is determined by the parents’ base levels.
The core formula is:
Resulting Base Level = floor((Demon 1 Base Level + Demon 2 Base Level) / 2) + 1
The game then finds the first demon of the calculated Resulting Race that has a Base Level equal to or higher than this number. If no demon is found with a higher level, it may wrap around to the lowest level demon of that race. This calculator uses this exact logic to predict your fusion results.
Fusion Variables
| Variable | Meaning | Unit / Type | Typical Range |
|---|---|---|---|
| Demon 1 | The first demon selected for fusion. | Demon (Name, Race, Level) | Level 1-99 |
| Demon 2 | The second demon selected for fusion. | Demon (Name, Race, Level) | Level 1-99 |
| Result Race | The Race of the demon that will be created. | Race Name (e.g., Fairy, Beast) | N/A |
| Calculated Level | The intermediate level calculated from the parents. | Numeric Level | 2-100 |
| Final Result | The final demon produced by the fusion. | Demon (Name, Race, Level) | Level 1-99 |
Practical Examples
Understanding the theory is one thing, but seeing it in action makes it clear. Here are a couple of realistic examples of using the shin megami tensei iv fusion calculator.
Example 1: Fusing a Fairy and a Beast
- Input Demon 1: Fairy Pixie (Level 2)
- Input Demon 2: Beast Kabuso (Level 7)
- Calculation:
- Result Race: According to the fusion chart, Fairy + Beast = Avian.
- Calculated Level: floor((2 + 7) / 2) + 1 = floor(4.5) + 1 = 4 + 1 = 5.
- Result: The calculator searches for the first ‘Avian’ race demon with a level of 5 or higher. This results in Avian Fuxi (Level 12).
Example 2: Fusing a Divine and a Foul
- Input Demon 1: Divine Angel (Level 4)
- Input Demon 2: Foul Slime (Level 6)
- Calculation:
- Result Race: According to the fusion chart, Divine + Foul = Fallen.
- Calculated Level: floor((4 + 6) / 2) + 1 = floor(5) + 1 = 6.
- Result: The calculator searches for the first ‘Fallen’ race demon with a level of 6 or higher. This results in Fallen Dantalion (Level 11).
How to Use This Shin Megami Tensei IV Fusion Calculator
This tool is designed to be intuitive and fast. Follow these simple steps to find your desired fusion result.
- Select Demon 1: Use the first dropdown menu to choose the first demon you want to fuse. The list is populated with many of the demons available in SMT IV.
- Select Demon 2: Use the second dropdown menu to select the second demon.
- View the Result: The calculator will automatically update. The “Fusion Result” box will display the name, race, and level of the demon you will create.
- Analyze Intermediate Values: The calculator also shows the base levels of the parent demons and the calculated average level, helping you understand how the result was reached.
- Reset: Click the “Reset” button at any time to clear your selections and start over.
Key Factors That Affect SMT IV Fusion
While the basic formula is straightforward, several other factors can influence fusion outcomes in Shin Megami Tensei IV.
- Demon Race
- The race of the two parent demons is the primary factor determining the race of the offspring, according to a fixed fusion chart. For example, fusing a Divine and a Jaki will always result in a Fairy.
- Demon Level
- The base levels of the parent demons are averaged to determine the resulting demon’s place within its race’s hierarchy. This is the core of the shin megami tensei iv fusion calculator‘s logic.
- Special Fusions
- Some powerful demons cannot be created through normal fusion. They require a specific, unique combination of two or more demons. These are not handled by the standard formula.
- Elemental Fusion
- Fusing two demons of the same race will produce an “Element” demon. Fusing an Element with another demon will rank that demon up or down within its own race, allowing you to access demons that might be hard to fuse otherwise.
- Fusion Accidents
- There is a small, random chance (normally around 1.6%) of a “fusion accident” occurring. This results in a different demon than expected, often a rare one. The chance increases if the demons being fused are “Foul” race or are “dead” (fainted).
- Compendium Registration
- Once you’ve acquired a demon, it’s registered in your Compendium. This allows you to re-summon it for Macca, which is crucial for completing complex or special fusions that require specific demons you may no longer have in your party.
Frequently Asked Questions (FAQ)
Q1: What happens if I fuse two demons of the same race?
Fusing two demons of the same race results in an “Element” demon. For example, Fairy + Fairy = Element.
Q2: Why is the result sometimes a lower level than the parents?
This can happen if the calculated level falls into a gap in the target race’s demon list, and the game wraps around to the lowest-level demon of that race. It is a normal, if sometimes undesirable, part of the fusion mechanics.
Q3: What is a fusion accident?
A fusion accident is a random event that produces an unexpected demon. The chance is normally 1/64 but can be increased by using Foul demons or fainted demons in the fusion. Some demons, like the “Famed” race, can only be acquired through these accidents.
Q4: Does this calculator account for special fusions?
No, this shin megami tensei iv fusion calculator focuses on the standard two-demon fusion formula, which covers the vast majority of fusions. Special fusions require specific recipes that are outside the scope of this general calculation.
Q5: Why can’t I fuse certain demons?
Some combinations are not possible. For example, you generally cannot fuse “special” demons or demons of the Element race in a standard fusion. If the calculator shows no result, the combination is likely invalid.
Q6: How does skill inheritance work?
Skill inheritance is a separate, complex system where the resulting demon can inherit skills from its parents. This calculator does not predict skill inheritance, as it focuses on correctly identifying the resulting demon itself. A fusion tool that includes skill paths is often a separate, more complex program.
Q7: Are there any exceptions to the fusion formula?
Yes. Besides special fusions and accidents, there are other minor exceptions. However, the formula implemented in this shin megami tensei iv fusion calculator is the foundational rule for the entire system.
Q8: Where do I find demons to fuse?
You can find demons in various locations throughout the game world, such as the Naraku dungeon or the Kiccigiorgi Forest. You can recruit them through negotiation in battle.
