Fatigue Game Settings
The following settings control how fatigue works:
| Setting | Default Value | Description |
|---|---|---|
| fFatigueBase | 1.0 | Base impact of low fatigue??? |
| fFatigueMult | 0.5 | Multiplier for impact of low fatigue??? |
| fFatigueReturnBase | 10.0 | Base fatigue regenerated per second |
| fFatigueReturnMult | 0.0 | Fatigue regenerated per second endurance multiplier |
| fFatigueRunBase | 8.0 | Fatigue burned per second when running |
| fFatigueRunMult | 0.0 | Fatigue burned per second when running encumberance multiplier |
| fFatigueJumpBase | 30.0 | Fatigue burned by jumping |
| fFatigueJumpMult | 0.0 | Fatigue burned by jumping encumberance multiplier |
| fFatigueCastBase | 1.0 | Fatigue burned by spell casting |
| fFatigueCastMult | 0.0 | Fatigue burned by spell casting encumberance??? multiplier |
| fFatigueAttackWeaponBase | 7.0 | Fatigue burned by attack |
| fFatigueAttackWeaponMult | 0.1 | Fatigue burned by attack weapon weight multiplier |
| fFatigueBlockBase | 0.0 | Fatigue burned by block base |
| fFatigueBlockMult | 1.0 | Fatigue burned by block skill/100 multiplier |
| fFatigueBlockSkillBase | 20.0 | Fatigue burned by block base |
| fFatigueBlockSkillMult | 0.0 | Fatigue burned by block skill multiplier |
| fPowerAttackFatiguePenalty | 5.0 | Fatigue burned by a power attack multiplier |
| fMarksmanFatigueBurnPerSecond | 15.0 | Fatigue burned per second when bow drawn by novice marksman |
| fMarksmanFatigueBurnPerShot | 5.0 | Fatigue burned per shot (by novice marksman???) |
| iMarksmanFatigueBurnPerSecondSkill | 20 | Unknown. Does not define max skill below which fMarksmanFatigueBurnPerSecond takes affect. |
| fPerkJumpFatigueExpertMult | 0.5 | Acrobatics Perk multiplier for fatigue burn when jumping |
| fPerkAthleticsXXFatigueMult | 1.0 -> 0.0 | Athletics Perk multipliers for fatigue burn when running. |
The following formulas are not all entirely confirmed, but should be pretty close. Unknowns are marked with ???.
The impact on things like attack damage of low fatigue is done calculated with a fatigue factor;
FatigueFactor = (fFatigueBase + Fatigue/MaxFatigue) * fFatigueMult
Fatigue regenerated per second is calculated as:
fatigue regenerated = fFatigueReturnBase + fFatigueReturnMult * Endurance
Fatigue burned per second when running is calculated as (fPerkAthleticsXXFatigueMult depends on athletics skill):
fatigue burned = (fFatigueRunBase + fFatigueRunMult * Encumberance/MaxEncumberance) * fPerkAthleticsXXFatigueMult
Fatigue burned by jumping is (fPerkJumpFatigueXXMult depends on acrobatics skill):
fatigue burned = (fFatigueJumpBase + fFatigueJumpMult * Encumberance/MaxEncumberance) * fPerkJumpFatigueXXMult
Fatigue burned by attacking is (fPowerAttackFatiguePenalty only applies for a power attack):
fatigue burned = (fFatigueAttackBase + fFatigueAttackMult * WeaponWeight) * fPowerAttackFatiguePenalty
Fatigue burned by spell casting is:
fatigue burned = fFatigueCastBase + fFatigueCastMult * Encumberance???SpellCost???
Fatigue burned by blocking is:
fatigue burned = fFatigueBlockBase + fFatigueBlockMult * Block/100 + fFatigueBlockSkillBase + fFatigueBlockSkillMult * Block
Note that the Apprentice block perk (reaching skill level iSkillApprenticeMin, default 25) is blocking burns no fatigue. Negative values for the *Mult settings work and make more sense than the defaults, as this makes fatigue burn decrease with increasing block skill. Encumbrance, shield weight, and damage of attack blocked have have no impact.
