Calculations for Fates? (2024)

I've been searching for some details about calculations of all sorts in Fates; how we get the numbers that we do in this game. So far I found a comprehensive account outside of Serenes Forest at http://www2.pegasusknight.com/wiki/fe14/index.php?%E8%A8%88%E7%AE%97%E5%BC%8F, but the formulas for combat forecasts and class bonuses seemed to be somewhat incomplete.

In light of the compilations of definitive formulas as we had for Awakening (http://serenesforest.net/awakening/miscellaneous/calculations/), I thought it might be worth having something analogous for Fates as well. I've listed below some information I could find so far, and tested some of it for myself with the game that I have, but I feel like this is too much of an undertaking to do it by myself. So I decided to post a thread to see if we can get more input from others in the forum who are interested.

In brief, the suggestion is to

- confirm that the formulas that we have are correct

- find out what other things we might wish to calculate and work on discovering/confirming those

(Posted in red are personal questions of mine)

Combat Stats*

Physical Attack = (Strength) + (Weapon Might) + (Weapon Rank Bonus)
Magical Attack = (Magic) + (Weapon Might) + (Weapon Rank Bonus)
Hit Rate = (Skill) x 3/2 + (Luck) x 1/2 + (Weapon Hit Bonus) + (Weapon Rank Bonus) + (Class Bonus)
Avoid Rate = (Speed) x 3/2 + (Luck) x 1/2 + (Weapon Avoid Bonus) + (Class Bonus)
Staff/Rod Hit Rate = (Magic) + (Skill) + (Staff/Rod Hit Rate) + (Weapon Rank Bonus) + (Class Bonus?)***
Staff/Rod Avoid Rate = (Enemy Resistance) x 3/2 - (Enemy Luck) x 1/2
Critical Rate = (Skill - 4) x 1/2 + (Weapon Critical Bonus) + (Class Bonus)
Dodge Rate**= (Luck) x 1/2 + (Weapon Dodge Bonus) + (Class Bonus)
Rating = (Strength) + (Magic) + (Skill) + (Speed) + (Luck) + (Defense) + (Resistance)

* Fractional values are rounded down to the nearest integer

** Undisplayed

*** Does Iago in Conquest Ch. 26 get Hit +5 in Staves for being a Sorcerer as well?

Combat Forecast*

Physical Damage = [(Strength) + {(Weapon Might) - (Ineffective Weapon Might Drop)} x (Effective Damage Coefficient) + (Weapon Rank Bonus) - (Enemy Defense) - (Enemy Terrain Bonus) + (Weapon Triangle Effects) + (My Castle Effects*) + (Effects from Skills)] x (Stance Coefficient)
Magical Damage = [(Magic) + {(Weapon Might) - (Ineffective Weapon Might Drop)} x (Effective Damage Coefficient) + (Weapon Rank Bonus) - (Enemy Resistance) - (Enemy Terrain Bonus) + (Weapon Triangle Effects) + (My Castle Effects) + (Effects from Skills)] x (Stance Coefficient)
Hit Rate for Weapons = (Unit Raw Hit Rate**) - (Ineffective Weapon Hit Drop) + (Ally Support Hit Bonus) + (Enemy Raw Avoid Rate) - (Enemy Support Avoid Bonus) - (Enemy Terrain Effect) + (Weapon Triangle Effects) + (My Castle Effects)
Hit Rate for Offensive Staves/Rods = (Unit Raw Staff/Rod Hit Rate) - (Enemy Raw Staff/Rod Avoid Rate) - (Enemy Support Bonus) - (Enemy Terrain Bonus) + (My Castle Effects)?
Critical Rate = (Raw Critical Rate) + (Support) - (Enemy Raw Dodge Rate) - (Support) - (Terrain Bonus) + (My Castle Effects)

* Fractional values are rounded down to the nearest integer

** Raw Rates refer to those indicated in the Combat Stats

*** My Castle Effects refer to buffs induced by buildings, accessories, and certain My Castle-related skills.

Note: In case of a critical attack, the actual damage dealt is one indicated on the Combat Forecast multiplied by 3. For Killer weapons (i.e. weapons that 'deal extra damage on critical hits'), the damage is instead multiplied by 4.

Note: Certain effects of skills that changes damage dealt/received are also taken into account, but at various stages

Skills that increase the main stats (Strength to Resistance) are reflected in the Combat Stats and Combat Forecast.
Skills that increase/decrease the combat stats (Attack, Hit rate, etc.) are reflected in the Combat Stats and Combat Forecast.
Skills that alter damage dealt or received (Rose's Thorns, Swordfaire, etc.) are reflected not in Combat Stats but are in Combat Forecast.*
Offensive Skills with activation rates (e.g. Luna, Astra) modify the damage from the one shown in the Combat Forecast and are calculated before critical hits.
Defensive Skills with activation rates (e.g. Pavise, Miracle) modify the damage from the one shown in the Combat Forecast and are calculated after critical hits.
