What is the Shin Megami Tensei V Vengeance Fusion Calculator?

The shin megami tensei v vengeance fusion calculator is a specialized tool designed to help players predict the outcome of demon fusion. In Shin Megami Tensei V: Vengeance, demon fusion is the primary method for strengthening your party by combining two or more of your allied demons to create a new, often more powerful, one. This calculator automates the process, removing guesswork and allowing you to strategize your party composition effectively. Whether you’re aiming for a specific demon or just exploring possibilities, this tool is indispensable.

The Demon Fusion Formula and Explanation

In most cases, standard demon fusion (Dyad Fusion) follows a specific formula. While the game does this for you, understanding the mechanics can give you an edge. The calculator uses this same logic.

Formula: Resulting Demon = Next demon of the target Race whose Base Level is ≥ ( (Base Level of Demon 1 + Base Level of Demon 2) / 2 ) + 1

In simple terms:

  1. The races of the two ingredient demons are cross-referenced on a fusion chart to determine the resulting demon’s race.
  2. The base levels of the two demons are averaged, and then one is added to the result.
  3. The game then finds the first demon of the target race whose own base level is equal to or higher than this calculated number.
Fusion Formula Variables
Variable Meaning Unit Typical Range
Base Level The innate level of a demon when first encountered or fused. Level 1 – 99
Race The demon’s family or type, which dictates fusion outcomes. (Categorical) e.g., Fairy, Foul, Divine, Dragon
Target Race The resulting Race determined by the fusion chart. (Categorical) N/A

Practical Examples

Example 1: Fusing Low-Level Demons

  • Inputs: Demon 1: Pixie (Fairy, Level 2), Demon 2: Preta (Haunt, Level 3)
  • Calculation: Intermediate Level = floor((2 + 3) / 2) + 1 = 3. The fusion of Fairy and Haunt results in a Night race demon.
  • Result: The lowest-level Night demon with a base level of 3 or higher is Sandman (Level 8).

Example 2: A Mid-Level Fusion

  • Inputs: Demon 1: Jack-o’-Lantern (Fairy, Level 20), Demon 2: Inugami (Beast, Level 24)
  • Calculation: Intermediate Level = floor((20 + 24) / 2) + 1 = 23. The fusion of Fairy and Beast results in a Holy race demon.
  • Result: The lowest-level Holy demon with a base level of 23 or higher is Shiisaa (Level 19), but since we need a higher level, the next is Unicorn. (Note: Real game data may vary; this is illustrative). Learning about the best demons SMT V Vengeance has to offer can guide your fusion choices.

How to Use This Shin Megami Tensei V Vengeance Fusion Calculator

  1. Select Demon 1: Use the first dropdown menu to pick your first ingredient demon from the list.
  2. Select Demon 2: Use the second dropdown to pick the second ingredient. The calculator will not work if both demons are the same.
  3. Calculate: Click the “Calculate Fusion” button.
  4. Review Results: The tool will display the resulting demon’s name, race, and base level. It also shows the intermediate calculated level to help you understand the process. A bar chart visually compares the levels of the demons involved.
  5. Reset: Click the “Reset” button to clear the inputs and start a new calculation.

Key Factors That Affect Demon Fusion

  • Demon Race: The combination of races is the most critical factor, as it determines the race of the resulting demon.
  • Base Level: As shown in the formula, the base levels of the ingredients directly influence the level of the resulting demon.
  • Special Fusions: Some demons can only be created through specific, often multi-demon, combinations and are not subject to the standard formula. Our calculator accounts for a few common special fusions. A full special fusion guide SMT V is recommended for these.
  • Player Level: You cannot fuse a demon whose base level is higher than your current protagonist’s level. The calculator does not account for your level, so keep that in mind.
  • Fusion Accidents: Sometimes, fusions can “fail” and result in a different, random demon. These are rare and cannot be predicted by any shin megami tensei v vengeance fusion calculator.
  • Unlocked Demons: Certain demons only become available for fusion after you defeat them in battle or complete specific side quests. Check out a guide to all abscess locations to make sure you’ve unlocked key areas.

Frequently Asked Questions (FAQ)

Why can’t I fuse a demon that’s shown in the calculator?
The most common reason is that your protagonist’s level is too low. You cannot create a demon with a base level higher than your own.
What is a Dyad Fusion?
Dyad Fusion is the standard two-demon fusion process that this calculator is based on.
What about Reverse Fusion?
Reverse Fusion allows you to see what demons you can make from your current stock and then shows you the ingredients. This tool is a “forward” calculator, where you provide the ingredients to see the result.
How are Special Fusions different?
Special Fusions require a specific set of 2 to 4 demons to create a powerful, unique result. They do not follow the normal fusion formula. For example, fusing King Frost, Baphomet, and Loa will always result in Black Frost.
Does this calculator include all demons from the game?
This calculator uses a representative subset of demons from SMT V: Vengeance to demonstrate the fusion mechanics. For a complete list, consulting a full demon compendium is advised.
What happens if a fusion “ranks down”?
If there is no demon of the target race at or above the calculated level, the game will typically select the highest-level demon of that race that is below the calculated level. This tool will indicate when no direct rank-up is available.
Are DLC demons included?
This calculator focuses on the base game demons. DLC-exclusive demons may have unique fusion properties not covered here.
How accurate is the shin megami tensei v vengeance fusion calculator?
The calculator’s logic is based on the well-established fusion mechanics of the Shin Megami Tensei series. For standard fusions, it is highly accurate. However, always double-check in-game before committing to a fusion.
