Thank you very much for considering my asking
I have tried out figure the total damages but It wasn't easy
here is the complete damage fomulas uesp.net
hope it can help you
The complete formula for Blades, Blunts and Bows is:
Damage = WeaponRating * (Fatigue/MaxFatigue + 1)/2 * SneakMultiplier * PowerAttackMultiplier
* OpponentArmorRating * OpponentWeaponResistance
The WeaponRating (WR) for Bows is the WR for the Bow + the WR for the Arrow.
Where WeaponRating is:
WeaponRating = BaseWeaponDamage * 0.5 * ( 0.75 + Attribute * 0.005 ) *
( 0.2 + ModifiedSkill * 0.015 ) * ( WeaponHealth/BaseWeaponHealth + 1 )/2
BaseWeaponDamage is the damage value provided on this site for the weapon.
WeaponRating is the damage shown for the weapon in your character's inventory.
Attribute and ModifiedSkill are constrained between 0 and 100.
Attribute is Strength for melee weapons; Agility for bows
ModifiedSkill is your skill (Blade, Blunt, or Marksman) modified according to Luck. The equation is ModifiedSkill = Skill + 0.4 * (Luck - 50)). Skill includes any skill-altering magical effects (Fortify, Damage, Absorb, etc; in the form of spells, potions, enchantments, abilities, etc). Luck also takes into account any magical effects.
SneakMultiplier is 1 unless your character is sneaking and undetected by the target in which case it is taken from the following table:
Sneak Skill SneakMultiplier
for One Hand Weapons SneakMultiplier
for Bows
0-24 4 2
25+ 6 3
PowerAttackMultiplier is the additional damage possible if the attacker chooses to do a power attack instead of a normal attack.
Normally the power attack multiplier is 2.5
If the attacker does a standing power attack and is at least apprentice level, then the power attack multiplier is 3
OpponentArmorRating is 1 if your character is successfully sneaking and has the Master Sneak perk, otherwise it is:
(100 - CombinedArmorRating) / 100
CombinedArmorRating may not exceed 85.
CombinedArmorRating is the sum of all pieces of armor the opponent is wearing and any boosting effects like Shield. The rating for each individual piece is:
BaseArmorRating * ( 0.35 + 0.0065 * OpponentArmorSkill) * ArmorHealth/MaxArmorHealth
OpponentWeaponResistance is the opponent's resistance to normal weapons; if using Silver/Daedric/Enchanted weapons it is always 1. Otherwise it is:
(100 - NormalWeaponResistance)/100
Enchantments on the weapon are handled as a spell hitting the target. The SneakMultiplier is not applied to either Enchantments or Poisons.
