Variables:

  • V (Variable Parent): The personal growth rate of the non-fixed parent (usually the Father, but depends on the pairing).
  • C (Child Base): The intrinsic personal growth rate assigned to the specific child character.
  • Class: The percentage bonus added by the unit’s current class (e.g., Swordmaster adds speed growth).

What is fe fates child growth calculator?

The fe fates child growth calculator is an essential tool for players of the tactical RPG Fire Emblem Fates (Birthright, Conquest, and Revelation). Unlike previous titles where child stats might be fully inherited or fixed, Fates utilizes a specific inheritance mechanic that blends parental potential with the child’s own capabilities.

Understanding this mechanic is crucial for “Min-Maxing”—the practice of optimizing characters for maximum combat efficiency. By carefully selecting parents (breeding), players can influence whether a child unit excels in Strength, Speed, or Magic, essentially customizing their army for higher difficulty settings like Lunatic Mode.

How to Calculate fe fates child growth calculator (Example)

Let’s calculate the Speed growth for a child unit, Kana, assuming the Avatar (Corrin) marries a fast unit.

  1. Identify Variable Parent Growth: Assume the parent has a 50% personal Speed growth.
  2. Identify Child Base Growth: Kana has a base personal Speed growth of 45%.
  3. Calculate Average: (50% + 45%) / 2 = 47.5%. The game typically rounds down, so 47%.
  4. Add Class Growth: If Kana is a Nohr Prince, add 15%.
  5. Final Result: 47% + 15% = 62% Total Growth Rate.

Frequently Asked Questions (FAQ)

Does the difficulty setting affect growth rates?

No, growth rates remain consistent across Normal, Hard, and Lunatic difficulties, though fixed growth modes exist in other franchise entries.

What happens if the average results in a decimal?

In Fire Emblem Fates, calculations involving decimals for growth inheritance are strictly rounded down (floored) to the nearest whole number.

Do Aptitude skills affect this calculation?

Yes, the skill “Aptitude” (available to Villagers or Mozu’s children) adds a flat +10% to all growth rates after the main calculation is complete.

Is the mother always the variable parent?

Not always. In Fates, the child is usually tied to the Father. However, for Azura (Shigure) and Female Corrin (Kana), the mother is the fixed parent and the father is variable.
