What is a FE Fates Child Growth Calculator?
A fe fates child growth calculator is a specialized tool used by Fire Emblem players to determine the stat growth percentages for the “Gen 2” or child units in Fire Emblem Fates (Birthright, Conquest, and Revelation). Unlike standard units who have fixed growth rates, children in this game inherit a unique blend of stats from both of their parents, plus their own base growth rates.
Strategic players use the fe fates child growth calculator to decide which characters to pair together (Support S-Rank) to create the most powerful offspring. Whether you are building a lightning-fast Swordmaster Shiro or a defensive tank Ignatius, understanding the math behind inheritance is crucial for late-game success and Lunatic difficulty runs.
A common misconception is that the child simply inherits the growth rates of the mother. In reality, the fe fates child growth calculator reveals that the child’s base rates act as a third variable, essentially averaging three distinct data points to find the final result.
FE Fates Child Growth Calculator Formula and Mathematical Explanation
The mathematical foundation of the fe fates child growth calculator is an arithmetic mean. Every character in the game has hidden growth rates—the percentage chance they have to increase a specific stat (like HP or Strength) when they level up.
The formula used by our fe fates child growth calculator is:
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Fixed Parent | The parent the child is naturally tied to (e.g., Ryoma for Shiro). | Percentage (%) | 10% – 70% |
| Variable Parent | The spouse selected for the fixed parent. | Percentage (%) | 5% – 75% |
| Child Base | The unique inherent growth value of the child unit. | Percentage (%) | 0% – 60% |
Practical Examples (Real-World Use Cases)
Let’s look at how the fe fates child growth calculator processes data for two popular pairings:
Example 1: Ryoma & Kagero (Parents for Shiro)
Using the fe fates child growth calculator for Shiro’s Strength stat:
- Ryoma (Fixed Parent) Strength Growth: 45%
- Kagero (Variable Parent) Strength Growth: 65%
- Shiro (Child Base) Strength Growth: 50%
- Calculation: (45 + 65 + 50) / 3 = 53.33% Strength Growth.
Example 2: Xander & Charlotte (Parents for Siegbert)
Using the fe fates child growth calculator for Siegbert’s HP stat:
- Xander (Fixed Parent) HP Growth: 45%
- Charlotte (Variable Parent) HP Growth: 70%
- Siegbert (Child Base) HP Growth: 40%
- Calculation: (45 + 70 + 40) / 3 = 51.66% HP Growth.
How to Use This FE Fates Child Growth Calculator
Our fe fates child growth calculator is designed for ease of use. Follow these steps to optimize your army:
- Select Child: Start by picking the child you want to optimize from the first dropdown. This automatically selects their “Fixed Parent.”
- Select Variable Parent: Choose the mother (or father, in the case of Female Corrin or Azura) from the second dropdown.
- Analyze Results: The fe fates child growth calculator immediately displays the percentage chances for all 8 stats: HP, Strength, Magic, Skill, Speed, Luck, Defense, and Resistance.
- Check the Chart: Use the visual bar chart to quickly identify the unit’s strengths and weaknesses.
- Compare Pairings: Change the variable parent to see how different marriages shift the growth totals.
Key Factors That Affect FE Fates Child Growth Calculator Results
When using a fe fates child growth calculator, keep these six critical factors in mind:
- Class Modifiers: The calculated growth rate is the *character’s* base. The unit’s current Class (e.g., Paladin vs. Swordmaster) adds its own growth rates on top of the calculated inheritance.
- Corrin’s Asset/Flaw: If calculating for Kana (Corrin’s child), the “Asset” and “Flaw” chosen during character creation significantly alter Corrin’s growth rates, which then trickle down through the fe fates child growth calculator.
- Gender Locking: Most children are tied to their fathers. However, Male Corrin produces Kana, and Azura produces Shigure, regardless of their spouse.
- Stat Caps: While the fe fates child growth calculator focuses on growth speed, inheritance also affects the “Stat Caps” (the maximum value a stat can reach), which uses a different (additive) formula.
- Offspring Seals: Children recruited later in the game receive “Offspring Seals,” which instantly level them up. Their stats at that point are still dictated by the rates found in the fe fates child growth calculator.
- Aptitude Skill: If a child inherits the “Aptitude” skill from Mozu, every growth rate effectively increases by 10%, a massive boost often calculated separately from the standard fe fates child growth calculator logic.
Frequently Asked Questions (FAQ)
Does the calculator include class growths?
No, this fe fates child growth calculator provides the unit’s personal growth rates. To find the total growth, you must add the specific Class Growth values found in-game to these results.
Who is the best mother for Shiro?
According to the fe fates child growth calculator, Kagero is excellent for Strength, while Hana or Hinoka are better for Speed builds.
How do I calculate Kana’s growths?
Kana’s inheritance is unique because Corrin’s growths change based on their Boon/Bane. Our fe fates child growth calculator uses Corrin’s neutral rates as a baseline.
Can I get 100% growth rates?
It is rare, but combining a high-growth parent with a high-growth class (like HP in Berserker) can push rates near or over 100% using the fe fates child growth calculator logic.
Does the order of parents matter?
No, the fe fates child growth calculator formula is commutative; (A+B+C)/3 is the same regardless of whether you swap Parent A and Parent B.
Are these rates the same for all three Fates paths?
Yes, the internal growth data used by the fe fates child growth calculator remains consistent across Birthright, Conquest, and Revelation.
Why is my child unit’s Resistance so low?
Many physical-oriented parents have low Resistance growth. Using a fe fates child growth calculator helps you identify if you need a magical mother like Sakura or Elise to fix this.
Does the child inherit skills too?
Yes, children inherit the last active skill from each parent, but this does not change the numerical growth rates calculated by the fe fates child growth calculator.
