To this forums braintrust: question on damage calculation.

I asked this in the statistics forum: Not one response.
I asked in the Amazon forum: One vague partial response.
So I come here. Lets test Jules accusation about this forum, shall we?:

Witchwild String Bow (WWS) fires level 20 Magic Arrows. How do we calculate the physical damage, and the 20% Magic Damage converted by the Magic Arrow when numerous damage enhancement mods are in effect?
Let us assume:
- Upgraded WWS with 100 average damage, due to 170% ED on the bow itself
- Dexterity = 200 (should yield +200% damage)
- High level Heart of the Wolvering (+ 200% damage, same on ranged?)
- High level Might aura (+200% damage, same on ranged?)
- Frequent Deadly Strike in effect (double damage)
- Occasional Amp Damage in effect (double damage)

OK, first off, how is the basic physical damage calculated. Like this?:
Enhancement percentages that are not intrensic to the weapon are added together then applied to base bow damage, i.e
+200% ED (dex)
+200% ED (HoW)
+200% ED (Might) =
+600% to base damage =
700 average damage, then modified by DS (1400) and Amp (2800)
But where does the Magic Arrows +20 to physical damage fit in?
At the beginning as base damage? after the dex? at the very end of the equation but before DS and Amp?

And what if you had equipment modifiers like + damage to demons (e.g. LOH +350% damage to demons?)

Once someone enlightens me on the base physical damage question, we turn to the conversion question: Is it 20% of the final physical damage value (including DS and Amp) that is converted to magic damage by MA? or does it convert some lesser number, like only the base bow or dex enhanced damage value?

So to recap my questions:
1) Did I get the damage enhancment mods forumula correct?
2) Where does the +20 straight damage from the lvl 20 MA fit in?
3) Are the + damage %'s from HoW and Might the same for ranged weps?
4) How would + damage % to demons/undead fit in?
5) Which number is used for the Magic Arrow 20% conversion to magic damage?

Any help appreciated.

Ok let me see if i can sort this out. Level 20 Magic arrow converts 20% physical damage to magic damage.

Converts X% Physical Damage To Magic Damage 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 . This is taken from Arreat Summit so feel free to check for yourself to double check my inferences.

So say your listed damage on your bow is 20-100 ( number for math sake) If I read it correctly the magic damage would be 16-80. That number in turn has "X" added to it

Damage +X 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

. So Im gathering your new damage would be 16-80 + 20. After all that your % modifiers kick in where applicable.

I hope I figured this correctly anyone feel free to contridict me because I could and might be wrong. How is that for an answer.

Ok, here's how it goes.

Step 1
I'll assume 80-120 (100 average) weapon damage for easier calculations.

• WeaponDamage = 80-120 (100 avg)

At this point we add all direct +damage from items (not skills!). You don't have any in your example so the damage stays at 80-120.


Step 2
Dexterity, +ED% from non-weapon and from skills are all bundled up including the +ED% to demons/undead.

• DamageBonus = 200%(dex)+200%(HoW)+200%(Might) = +700%ED

• Ok, so far the damage is: WeaponDamage * DamageBonus = 640-960 (800 avg)

At this point we also add elemental damage (none in this example) and +damage from skills like Magic Arrow (or Bash). Level 20 MA adds damage +20.

• TotalDamage = 660-980 (820 avg)


Step 3
If you're using a skill with damage penalty like Multiple Shot or Strafe it is calculated here. We skip it in this example, because we're talking about Magic Arrow.


Step 4
I'm assuming 100% Deadly Strike for, again, easier calculations.

• FinalDamage = TotalDamage * 2 (100%DS) = 1320-1960 (1640 avg)

At this step we convert the 20% of the above damage to magical damage

• FinalPhysicalDamage = FinalDamage * 0.80 = 1056-1568 (1312 avg)
• FinalMagicalDamage = FinalDamage * 0.20 = 264-392 (328 avg)

Sum of these damages is the value shown in the character screen.


Step 5
Next we calculate how much damage the monster takes. I'm assuming the target monster has 50% physical resistance and 0% magical resistance. Amplify Damage lower monsters physical resistance by 100% so the said monster has -50% physical resistance under Amplify Damage.

• InflictedPhysicalDamage = FinalPhysicalDamage * 1.5 = 1584-2352 (1968 avg)
• InflictedMagicalDamage = FinalMagicalDamage * 1.0 = 264-392 (328 avg)


That should be all. I hope I haven't forgotten something important or miscalculated something.

Just had to fire a comment at me didnt ya?

Liessa: Outstanding explanation, answered my questions, many thanks. Only one error I can see, you added the 3 200% EDs to total 700 vice 600%, I think.

Jules: Well I thought it was a pretty harmless comment. And you did make that accusation....
