What is the SMTV Vengeance Fusion Calculator?

The smtv vengeance fusion calculator is a specialized tool designed to help players of Shin Megami Tensei V: Vengeance predict the outcomes of demon fusion. Fusion is a core mechanic in the game where two or more demons are combined to create a new, often more powerful, one. This calculator simplifies the complex fusion rules, allowing players to strategically build their team of demons. Whether you are a new player or a seasoned veteran, using a fusion calculator is one of the best ways to explore the hundreds of demons available and optimize your party for the challenges of the Netherworld.

SMTV Vengeance Fusion Formula and Explanation

In Shin Megami Tensei V: Vengeance, standard two-demon fusion follows a predictable formula. The game first determines the race of the resulting demon based on the races of the two ingredient demons. Then, it calculates a new base level to find the specific demon within that race.

The core formula is:

Resulting Level = floor((Base Level of Demon 1 + Base Level of Demon 2) / 2) + 1

The game then searches for the first demon of the target race whose base level is equal to or higher than this “Resulting Level.” This system is fundamental to the smtv vengeance fusion calculator‘s logic.

Variables Table

Variables used in the SMTV fusion calculation.
Variable Meaning Unit Typical Range
Demon 1 The first selected demon for fusion. Demon Name Any demon in your possession.
Demon 2 The second selected demon for fusion. Demon Name Any demon in your possession.
Base Level The innate starting level of a demon. Level 1 – 99
Resulting Demon The demon created from the fusion. Demon Name Varies based on ingredients.

Practical Examples

Example 1: Fusing Pixie and Preta

  • Input Demon 1: Pixie (Race: Fairy, Base Level: 2)
  • Input Demon 2: Preta (Race: Foul, Base Level: 4)
  • Calculation: floor((2 + 4) / 2) + 1 = 4
  • Result: The resulting race from Fairy + Foul is Haunt. The calculator searches for a Haunt demon with a base level of 4 or higher. In this case, the result is Slime (Race: Haunt, Base Level: 8).

Example 2: Fusing Angel and Apsaras

  • Input Demon 1: Angel (Race: Divine, Base Level: 10)
  • Input Demon 2: Apsaras (Race: Nymph, Base Level: 12)
  • Calculation: floor((10 + 12) / 2) + 1 = 12
  • Result: The resulting race from Divine + Nymph is Flight. The calculator finds the first Flight demon at or above level 12, resulting in Archangel (Race: Divine, Base level 18, but a different combination is needed for it. Let’s assume a hypothetical Flight demon for this example). For more accurate results, you can use our Demon Compendium.

Key Factors That Affect SMTV Vengeance Fusion

  • Demon Race: The race of the two ingredient demons is the primary factor in determining the race of the result. Our Fusion Charts page has detailed tables.
  • Base Level: As shown in the formula, the base levels of the ingredients determine the target level for the resulting demon.
  • Special Fusions: Some powerful demons can only be created through specific, fixed combinations of two, three, or even four demons. These do not follow the standard formula.
  • Player Level: You cannot fuse a demon whose base level is higher than your current protagonist’s level.
  • Fusion Accidents: Occasionally, a fusion will “fail” and result in a different, often rare, demon.
  • Compendium Registration: Registering demons allows you to summon them again for a fee, making them available for future fusions even after they’ve been used. See our guide on Managing Your Compendium for tips.

Frequently Asked Questions (FAQ)

1. Why can’t I fuse two demons of the same race?

In most cases, fusing two demons of the same race does not produce a result. The fusion system is designed to create new types of demons by combining different lineages.

2. What is a fusion accident?

A fusion accident is a random event where the planned fusion fails and produces an unexpected demon. The chances of this happening can be influenced by certain in-game conditions.

3. How does this smtv vengeance fusion calculator handle special fusions?

This calculator focuses on standard fusions. For a complete list of specific combinations, please visit our Special Fusions List.

4. Why is the resulting demon a lower level than one of the ingredients?

This can happen if the calculated average level is low and the next available demon in the target race has a low base level. Fusion is not always about getting a higher-level demon, but often about getting a specific race or skill set.

5. Can I influence the skills the new demon inherits?

Yes. When you perform a fusion, you can select which inheritable skills from the ingredient demons are passed on to the new demon. Planning skill inheritance is a key strategy.

6. What are “unitless” values in this context?

In this calculator, “Level” is the primary unit. The demon names and races are categorical data and are therefore “unitless” in a mathematical sense.

7. Does the “Vengeance” storyline change fusions?

Yes, the Canon of Vengeance route introduces new demons and some exclusive fusions not available in the original SMT V storyline. Our Vengeance-exclusive demons guide has more info.

8. How accurate is this smtv vengeance fusion calculator?

This calculator is based on the standard, well-documented fusion mechanics of the Shin Megami Tensei series. It is highly accurate for normal fusions but does not account for special fusions or random accidents.
