What is the SMT V Vengeance Fusion Calculator?

The smt v vengeance fusion calculator is a specialized tool designed to simplify one of the most critical mechanics in Shin Megami Tensei V: Vengeance—demon fusion. Fusion is the process of combining two or more demons in your party to create a new, often more powerful, demon. This calculator focuses on “Dyad Fusion,” which involves two demons. It helps you predict the base level of the resulting demon, which is the first step in determining the exact outcome of your fusion experiment. By knowing the resultant level, you can consult a fusion chart to see which demon of a specific race you will create.

This tool is indispensable for players who want to strategically build their team, customize skill sets, and unlock the most powerful demons in the game without costly trial and error.

SMT V Fusion Formula and Explanation

The core of the smt v vengeance fusion calculator is based on a straightforward formula that the game uses for standard Dyad fusions. When you fuse two demons, the game first calculates a median level to determine the base for the new demon.

The formula is as follows:

Resulting Base Level = Floor( (Base Level of Demon A + Base Level of Demon B) / 2 ) + 1

This calculated level is then used to look up a result from a predetermined fusion chart, which is based on the races of the two demons being fused. For more complex outcomes, you may want to consult a guide on Special Fusions.

Variable Explanations for Fusion Calculation
Variable Meaning Unit Typical Range
Base Level of Demon A The innate level of the first demon being fused. Level (integer) 1 – 99
Base Level of Demon B The innate level of the second demon being fused. Level (integer) 1 – 99
Resulting Base Level The calculated level used to determine the final fused demon. Level (integer) 2 – 100

Practical Examples

Example 1: Early Game Fusion

Let’s say you want to fuse a Level 12 Angel with a Level 16 Apsaras.

  • Inputs: Demon A Level = 12, Demon B Level = 16
  • Calculation: Average is (12 + 16) / 2 = 14. The floor of 14 is 14. Add 1.
  • Result: The Resulting Base Level is 15. You would then check your fusion chart for the result of a Divine x Nymph fusion to see which demon is at or just above level 15.

Example 2: Mid-Game Fusion

Imagine you are fusing a Level 41 Kaiwan with a Level 48 Orthrus. For more details on demon fusion, see our SMT V Demon Fusion Guide.

  • Inputs: Demon A Level = 41, Demon B Level = 48
  • Calculation: Average is (41 + 48) / 2 = 44.5. The floor of 44.5 is 44. Add 1.
  • Result: The Resulting Base Level is 45. This calculated level is your key to finding the powerful new demon you can create.

How to Use This SMT V Fusion Calculator

Using this calculator is simple and designed to give you quick, accurate results to aid your journey through Da’at.

  1. Enter Demon A’s Level: In the first input field, type the base level of one of the demons you wish to fuse.
  2. Enter Demon B’s Level: In the second field, type the base level of the other demon.
  3. Calculate: Click the “Calculate” button.
  4. Interpret Results: The tool will display the Resulting Base Level. This is the number you need. It also shows the average of the parents’ levels as an intermediate step. Use this result with a fusion chart to find your new demon. You may want to review our Shin Megami Tensei V Walkthrough for more help.

Key Factors That Affect Fusion

While this smt v vengeance fusion calculator handles the level calculation, several other factors determine the final outcome and strength of the fused demon.

  • Demon Races: The combination of the two parent demon races (e.g., Fairy and Beast) determines the race of the resulting demon, which in turn dictates which demon list to check against the calculated level.
  • Special Fusions: Some demons cannot be created through normal Dyad fusion. They require specific combinations of three or more demons and are unlocked through gameplay.
  • Player Level: You cannot fuse a demon whose base level is higher than your own current level (until a specific Miracle is unlocked late game).
  • Skill Inheritance: The resulting demon can inherit a set number of skills from its parents, allowing for powerful customization. Understanding skill affinities is crucial.
  • Fusion Accidents: On rare occasions, a fusion will “fail” and result in a different, often rare, demon than expected.
  • Compendium Registration: Keeping your Demon Compendium updated ensures you can always re-summon a powerful demon you’ve fused or dismissed.

Frequently Asked Questions (FAQ)

What is a Dyad Fusion?

A Dyad Fusion is the most common type of fusion in SMT V, involving the combination of two demons.

Does the current level of my demons matter, or only the base level?

For calculating the fusion result, only the base level of the parent demons is used. However, demons at higher levels may pass on more powerful skills.

Why can’t I fuse a specific demon?

There are several reasons. The resulting demon’s level might be higher than your protagonist’s level, it might be a Special Fusion requiring a unique combination, or you may not have unlocked it yet.

What is the “floor” function in the formula?

The “floor” function simply means to round the number down to the nearest whole number (e.g., the floor of 44.5 is 44).

How does this calculator help with Special Fusions?

This calculator is specifically for Dyad (two-demon) fusions. Special Fusions have fixed recipes and do not use this level-averaging formula. You should consult a list of all special fusions for those.

What is a fusion accident?

A fusion accident is a random event where the fusion process goes wrong and creates an unexpected demon, which is sometimes a rare one you can’t get otherwise.

Is this calculator updated for the Vengeance version of SMT V?

Yes, the core Dyad fusion formula remains the same in Shin Megami Tensei V: Vengeance, making this calculator accurate for the updated game.

Where do I find a fusion chart?

Fusion charts are often compiled by the game’s community and can be found on fan wikis, forums, and guide websites.
