Physical Damage Calculation

Hi!

I'm wondering in what order and with what weight the damage multipliers go into the equasion to calculate damage per hit.

Let's take as an example:

Weapon base damage = x
Weapon affix with flat damage = y
Ring with flat damage affix = z
Weapon affix increased % damage = A
Passive Skill with increased% damage = B
Gem Multistrike: less damage = C,
Gem Multistrike: increased % damage = D
Gem Melee damage: more % melee damage = E
Gear, iE Rustic Sash: increased % damage = F

Question 1:
How is "flat damage" calculated?
Is it simple x+y+z?

Or is the ring out of the calculation because its not on the weapon?
Like ((x+y)*whatever + z)*whatever

Question 2:
C and E, are those equal?
(1-C+E) or (1-C)*(1+E)?

Question 2a)
I'm right taking "less" and "more" as twins, right?
"Less" in multistrike would not be a drawback if it had to run up against something like +500% increased from tree and gear... ;)

Question 3:
"Increased", does it matter where I got it from? Are A, B, D and F equal?
Or is A different from the rest because it's local on the weapon?
Is B different from C and F?

---

So is this "most intuitive approach" correct?

Physical damage per Hit = (x+y+z) * (1+A+B+D+F) * (1-C+E)

Or is it, because A is on the weapon

Physical damage per Hit = (x+y+z) * (1+A) * (1+B+D+F) * (1-C+E)

Or is it, because z is not on the weapon

Physical damage per Hit = ((x+y)*(1+A)+z) * (1+B+D+F) * (1-C+E)

Or is it something completly different, because of (Question 3) the increased sources are not equal?

---

I understand that "more is more" (the higher increase I get, the better my DpS will be), but for minmaxing gear, gems and skilltree it would be interesting to see which variable is stronger than others...

[ [(x+y)*(1+A)] + z ] * ( 1+B+D+F ) * ( 1+C ) * (1+E)
---weapon------flat phy---increased-----more-----less---


Notes:
“A” is local phy dmg modifier therefore not applied on a global scale
“increased/decreased dmg” applies on the base phy and is stacks additively
“more/less dmg” applies multiplicatively on the overall dmg [edit: as below]
"notation" 30% more is 0.3 in above terminology

Base Damage = (x+y)*(1+A)+z

End damage = Base Damage * (1+B+D+F)*(1+C)*(1+E)

Less and More are multiplicative, not additive, unless they're from the same source (IE the shock status effect gives 30% more damage taken per stack, but these are not multiplicative with themselves).

This last problem can be easily tested.

If LESS and MORE stacks additively, then melee physical damage gem more than makes up for the loss.
1-36% + 48% > 1 (48% being Lvl 19 melee phys damage gem)

So if I link the 2 gems to whatever attack, the physical damage per hit goes up.

If it is multiplicative, then you would need more damage than the gem can provide:

1<(1-0,36)(1+x) => x has to be higher than 56,25% to increase damage.
So damage per hit goes down.

Have to start PoE to test I guess.

(how much does lvl20 q20 melee phys damage give?)

Ok ok, I believe you... ^^

Last question: Strength gives just increased damage like any passive node from the tree?

5str = 1% increased physical dmg

it's physical dmg =) but it fit's into the increased category

Strength gives an "increased" damage mod (additive with other "increased" modifiers) that applies to melee physical damage. Same as some of the nodes around the scion, marauder, duelist, and templar starts.

That's what I meant, yes, I was only to lazy to write the full "increased melee physical damage %".

Thx!
