i have a weapon with 16-40 physical damage
i have +107.8% physical damage from cunning and +8% physical damage from a piece of armor
I think i should do 115.8% more physical damage so i should do 34-86 physical damage approximately but i do 21-53. Why ?
Are you using some kind of damage conversion?
Nope i am not using damage conversion
Is your weapon a sword? Armor Piercing would convert Physical to Piercing.
You haven’t really given us enough info to work with. A picture would help.
Here is more clear
weapon: 16-40 physical / Bonus: +93.1% physical / but still 19-47 physical how does it works ? because when i use other weapons the percentages are ok but with pistols is like that. Is physical being converted into pierce?
amour piercing = physical damage converted to piercing damage

What Feralwarlord said. You have 30% Armour Piercing base and that is increased by 30% to 39% Armour Piercing, meaning 39% of your Physical damage after % bonuses becomes Pierce damage.
If you take your 34-86 Physical damage and multiply it by (1-0.39) or 0.61 and round the numbers up, that is where your actual damage numbers are from.

Thanks people 
Is this right? I thought it would be:
Let x = base physical damage
Then:
(0.39 * x) * pierce bonuses = final pierce damage
((1-0.39) * x) * physical bonuses = final physical damage
Essentially, the pierce ratio operates on base physical damage, which is then scaled separately by your physical and pierce bonuses respectively.
yes armor piercing is converting base physical damage
You should get the same result regardless whether you’re converting base damage then applying % bonuses or applying % bonuses then converting though right?
nope you convert first then apply the damage bonus for the new damage type
That is usually how I go about it to keep things orderly but both values are multipliers, so order shouldn’t matter unless there’s another, separate and different step in-between.
Taking Zeiker’s initial numbers to calculate the resultant Physical damage. 16 * 2.158 * 0.61 is no different to 16 * 0.61 * 2.158 where:
- 16 is the base damage.
- 2.158 is 115.8% for the damage bonus.
- 0.61 is the Physical damage ratio after Armour Piercing.
It does not matter in this particular example no
On the physical component, order doesn’t matter. However, the original wording that I was disputing was
Which says, to me, that you apply %physical damage, then convert that damage to Pierce damage. This is wrong, as pierce has its own % damage. I think it’s clearer to apply pierce ratios beforehand, as that clearly separates which is scaled by which %damage.
Of course, so long as you get the correct results it doesn’t matter - I just think it’s clearer to process it in that way, unless my assumptions are wrong.
I see what you’re saying now and you’re right that it would be neater to separate the Physical and Pierce out that way.
