What is SMTV Vengeance Fusion?

Shin Megami Tensei V (SMTV) introduces a complex and rewarding fusion system that allows players to combine demons to create more powerful allies. The “Vengeance Fusion” aspect often refers to the strategic decisions and calculations involved in ensuring successful fusions, especially when aiming for specific outcomes like skill inheritance or achieving high success rates for powerful demons. Understanding the mechanics behind demon fusion is crucial for progressing through the game, overcoming challenging bosses, and building an optimal team. This SMTV Vengeance Fusion Calculator is designed to demystify these calculations, providing players with the insights needed to make informed decisions during the fusion process.

Who should use it?
This SMTV Vengeance Fusion Calculator is for any Shin Megami Tensei V player who engages with the demon fusion system. Whether you are a new player trying to understand the basics or an experienced player aiming for min-maxed demon builds, this tool can help. It’s particularly useful for players who:

• Are trying to fuse a specific demon and want to maximize their chances.
• Want to ensure valuable skills are inherited during fusion.
• Are curious about the underlying mechanics of SMTV fusion.
• Wish to estimate the cost (in M.A.C. or Magnetite) associated with different fusion attempts.
• Are utilizing Mitamas to boost fusion stats or success rates.

Common misconceptions about SMTV Vengeance Fusion:
One common misconception is that fusion is purely random. While randomness plays a role, SMTV’s fusion system is heavily influenced by the levels of the component demons, their types, and the presence of special items like Mitamas. Another misconception is that fusion is only about creating the strongest demons; it’s also about strategic skill transfer, which requires careful planning. Players might also underestimate the impact of Mitama types, viewing them as minor stat boosts rather than significant factors in success rates and overall fusion outcomes. Finally, some players might not realize the game calculates costs based on demon levels and types, leading them to overspend unnecessarily.

SMTV Vengeance Fusion Formula and Mathematical Explanation

The SMTV Vengeance Fusion Calculator operates on a set of formulas derived from the game’s mechanics, aiming to quantify the probability of a successful fusion and estimate associated costs. These formulas are approximations based on observed game behavior and known mechanics.

Step-by-step derivation:

1. Base Success Rate Calculation: This forms the foundation of fusion probability. It’s influenced by the levels of the demons involved. A higher combined level generally leads to a higher base success rate.
2. Mitama Bonus Application: Mitamas provide a direct numerical bonus to the fusion success rate, varying based on the type of Mitama used. This bonus is added to the base success rate.
3. Skill Inheritance Factor: The player’s desired skill inheritance chance is applied multiplicatively. This represents the likelihood that a specific, targeted skill will be passed down from the component demons to the resulting fusion.
4. Final Success Rate Determination: The effective success rate is calculated by combining the adjusted base rate (with Mitama bonus) and then factoring in the desired skill inheritance chance.
5. Estimated Cost Calculation: The cost, often in Magnetite (M.A.C.), is primarily determined by the level of the base demon and the complexity of the fusion (number of demons required, Mitama influence).

Variable Explanations:

Let’s break down the variables used in our SMTV Vengeance Fusion Calculator:

• Base Demon Level: The level of the primary demon selected for the fusion.
• Skill Inheritance Chance: The player’s input percentage representing how likely it is for a specific, desired skill to be passed on. This is a player’s target, not a fixed game mechanic value.
• Mitama Type: The type of Mitama used in the fusion (if any), which adds a bonus.
• Demons Required: The total count of demons needed for the specific fusion recipe.
• Demon Level Range: A factor often related to the level difference between potential fused demons, influencing the base calculation.

Practical Examples (Real-World Use Cases)

Let’s illustrate how the SMTV Vengeance Fusion Calculator works with practical scenarios:

Example 1: Fusing a High-Level Demon with Skill Inheritance

Scenario: You want to fuse Kikuri-Hime (a powerful support demon) which requires 4 demons. You have a base demon at level 70, and you want to ensure a specific rare skill has a 60% chance of inheriting. You decide to use a Light Mitama (Unicorn) for its significant bonus.

Inputs:

• Base Demon Level: 70
• Skill Inheritance Chance: 60%
• Mitama Type: Light (Unicorn) – Value 50
• Demons Required: 4
• Demon Level Range: 5

Calculation Steps (Conceptual):

• Base Success Rate: (70 + avg_other_levels) / (avg_level * 1) * 5. Let’s assume an average level of 65 for the other demons, making the calculation roughly (70 + 65*3) / 65 * 5 = 10.77 * 5 ≈ 54%.
• Mitama Bonus: 50 (from Light Mitama)
• Effective Success Rate: (54% + 50) * (60% / 100) = 104% * 0.60 = 62.4%
• Estimated Cost (MAC): 70 * (4 + 50) * 0.8 = 70 * 54 * 0.8 = 3024 M.A.C.

Calculator Output:

• Base Success Rate: ~54%
• Mitama Bonus: 50
• Effective Success Rate: ~62.4%
• Estimated Cost (MAC): ~3024
• Main Result (Effective Success Rate): 62.4%

Interpretation: This indicates a decent chance of success for the fusion itself, and a 62.4% probability that your targeted skill will be inherited. The cost is substantial but manageable given the demon’s utility.

Example 2: Low-Level Fusion Without Mitama

Scenario: You are fusing a low-level demon, requiring only 2 demons. Your base demon is level 15. You are not using any Mitama and are not particularly focused on skill inheritance for this specific fusion, setting a low target of 30%.

Inputs:

• Base Demon Level: 15
• Skill Inheritance Chance: 30%
• Mitama Type: None – Value 0
• Demons Required: 2
• Demon Level Range: 3

Calculation Steps (Conceptual):

• Base Success Rate: (15 + avg_other_levels) / (avg_level * 1) * 5. Assume avg level of 12. (15 + 12) / 12 * 5 = 2.125 * 5 = 10.625% ≈ 11%.
• Mitama Bonus: 0
• Effective Success Rate: (11% + 0) * (30% / 100) = 11% * 0.30 = 3.3%
• Estimated Cost (MAC): 15 * (2 + 0) * 0.8 = 15 * 2 * 0.8 = 24 M.A.C.

Calculator Output:

• Base Success Rate: ~11%
• Mitama Bonus: 0
• Effective Success Rate: ~3.3%
• Estimated Cost (MAC): 24
• Main Result (Effective Success Rate): 3.3%

Interpretation: As expected, the base success rate is low due to the low levels. The low skill inheritance target further reduces the effective rate. However, the cost is negligible. This scenario highlights that fusions involving low-level demons are less predictable and may require multiple attempts for desired outcomes.

How to Use This SMTV Vengeance Fusion Calculator

Using the SMTV Vengeance Fusion Calculator is straightforward. Follow these steps to get accurate results for your demon fusion needs:

1. Input Base Demon Level: Enter the level of the primary demon you are using for the fusion.
2. Specify Skill Inheritance Chance: Input the percentage chance you desire for a specific skill to be passed down during the fusion. This is your target probability.
3. Select Mitama Type: Choose the type of Mitama you are using from the dropdown menu. If no Mitama is used, select “None”.
4. Enter Demons Required: Input the total number of demons specified in the fusion recipe for the demon you are trying to create.
5. Provide Demon Level Range: Enter the typical level difference range you expect among the demons involved in the fusion. This influences the base success rate calculation.
6. Click ‘Calculate Fusion’: Once all fields are filled, click the button to see the results.

How to read results:

• Main Result (Effective Success Rate): This is the highlighted primary output, showing the overall probability of achieving your desired fusion outcome, factoring in Mitama bonuses and your skill inheritance target. Aim for higher percentages for more reliable results.
• Base Success Rate: This shows the fusion’s inherent probability based purely on demon levels.
• Mitama Bonus: The numerical value added by the selected Mitama.
• Effective Success Rate: The calculated probability after applying Mitama bonuses and the skill inheritance target.
• Estimated Cost (MAC): An approximation of the Magnetite (M.A.C.) required for the fusion, useful for resource management.

Decision-making guidance:
Use the Effective Success Rate as your primary guide. A higher percentage means a more reliable fusion. If the rate is too low, consider:

• Using higher-level demons.
• Using a more potent Mitama (e.g., Light or Dark).
• Adjusting your target Skill Inheritance Chance if it’s unrealistically high.
• Revisiting the fusion recipe to ensure you’re using the correct number of demons.

The Estimated Cost (MAC) helps you plan your resources. Higher-level fusions and the use of potent Mitamas will naturally increase the cost. Always ensure you have sufficient M.A.C. before attempting critical fusions. For important skill inheritance, consider the trade-off between the success rate and the cost.

Key Factors That Affect SMTV Vengeance Fusion Results

Several factors influence the success and outcomes of demon fusions in Shin Megami Tensei V. Understanding these can help you strategize and achieve your desired results more consistently.

1. Demon Levels: This is perhaps the most significant factor affecting the base success rate. Higher-level component demons generally lead to a higher probability of a successful fusion. The game’s internal calculations heavily weigh the levels of the demons involved.
2. Mitama Types: Mitamas are crucial for enhancing fusion outcomes. Each type (Fortuna, Agni, Garuda, etc.) provides a specific numerical bonus to the fusion success rate. Light and Dark Mitamas typically offer the highest bonuses, making them valuable for critical fusions. Their bonus directly increases the likelihood of a successful fusion.
3. Fusion Recipe Complexity: The number of demons required for a specific fusion recipe impacts both the cost and potentially the success rate. More complex fusions might have different inherent probabilities or require higher-level components. This calculator uses ‘Demons Required’ to influence cost estimations.
4. Skill Inheritance Probability: While the game has an overall fusion success rate, inheriting specific skills involves a separate probability. This calculator allows you to set a target percentage for this, representing your desired outcome for skill transfer. High desired inheritance chances might be harder to achieve alongside a successful fusion.
5. Demon Archetypes and Race: Although not explicitly calculated in this simplified model, the specific demon race and type can influence which skills are inherited and the resulting demon’s stats. Certain skill types are more likely to be passed down within specific demon families.
6. Player Strategy and Input Accuracy: Ultimately, the player’s choices in selecting demons, Mitamas, and understanding the fusion mechanics are key. Accurately inputting data into tools like this calculator ensures the most relevant results. Misinterpreting demon levels or the number of required demons can lead to inaccurate expectations.
7. Magnetite (M.A.C.) Cost: While not directly affecting the success *rate*, the cost is a critical factor in the *feasibility* of repeated fusion attempts. Higher-level fusions and the use of Mitamas significantly increase M.A.C. expenditure. Players must balance the desire for success with resource availability.
8. Inflation/Deflation (Conceptual): In a broader sense, the “value” of demons and skills can change as the player progresses. Early game, a level 15 demon might be significant; late game, it’s trivial. This affects the perceived importance and cost-effectiveness of fusion attempts.

Frequently Asked Questions (FAQ)

What is the difference between Base Success Rate and Effective Success Rate?

The Base Success Rate is the initial probability calculated by the game based primarily on the levels of the demons being fused. The Effective Success Rate is the final calculated probability shown by the calculator, which incorporates the Base Success Rate, any Mitama bonuses, and factors in your desired Skill Inheritance Chance.

Can I guarantee a specific skill inheritance?

No, you cannot guarantee a specific skill inheritance. The calculator provides a probability (Effective Success Rate), but fusion outcomes still involve an element of chance. You can increase your odds by aiming for higher effective rates through careful selection of demons and Mitamas.

How does the Demon Level Range affect the calculation?

The Demon Level Range is used in the Base Success Rate calculation to approximate the influence of the level differences between the component demons. A wider range might imply more variability, potentially affecting the base success calculation.

What is M.A.C. and why is it important?

M.A.C. stands for Magnetite, the primary currency used for demon fusion in SMTV. It’s essential for performing fusions, and the cost increases with the level and complexity of the fusion. Managing your M.A.C. is crucial for consistent progression.

Are there specific demon combinations that increase success rates?

While the calculator focuses on levels and Mitamas, the specific demon race combinations determine the outcome demon. Certain combinations might have slightly different inherent probabilities or skill pools, but the core success rate is heavily tied to levels.

Do elemental affinities matter for fusion success?

Elemental affinities primarily affect a demon’s strengths, weaknesses, and the skills they can learn or inherit. They do not directly impact the base fusion success rate calculation in SMTV, though they are vital for building a balanced team.

What is the best Mitama to use?

The “best” Mitama depends on your goal. Light (Unicorn) and Dark (Barghest) Mitamas offer the highest numerical bonuses to success rate. However, using Mitamas increases fusion costs. For general fusion success, they are highly recommended.

Can I use this calculator for other Shin Megami Tensei games?

This calculator is specifically tuned for Shin Megami Tensei V’s fusion mechanics. While older SMT games share similarities, their fusion formulas and mechanics might differ, potentially yielding inaccurate results if used for other titles.
