PonDeRing about PDR

Lame caps pun aside, is PDR a straight subtraction or is it a multiplication?

Like say a mob has 50% PDR, and I have max Combat Mastery, is it:

1 - (0.5 x (1-0.4)) = 0.7, 70% damage, 30% net PDR

or is it

1 - (0.5 - 0.4) = 0.9, 90% damage, 10% net PDR?

It's the first one according to a few old ass threads that I can't remember how to find. If you want to take this with a grain of salt then by all means.

There's still a couple of people who believe its the second one, but it should be easily deniable (as in, verify that it isn't) on a hero due to the big difference between 10% and 30% pdr.


Really would like to know if this is wrong though. Because all of my calculations have been based off of method 1.

I literally just tested and both are like.. wrong.
I must be doing something wrong here, lol.

 Spoiler

Code:

[((Damage Range*Skill%)*Critical)*Y]* DamageInc
10796~12701

Maxed Marksmanship: 20% ignore.
Monster def: 10% PDR
Suggested: y=(def-ignore)/100 y>-1
Suggested: y=def*ignore y>-1
Suggested 1: 0% defence
Suggested 2: 8% defence.
Suggestion 1 Range: 10796-12701
Suggestion 2 range: 9932-11684
Maximum observed(no crit): 12061
Minimum observed(no crit): 10082
Conclusion: no idea.

This was tested with my bowmaster with just a bow on on rashes. No total damage or anything.

Edit: tested more and minimum was 9987.

Option 3:
30% ignore pdr = 100% pdr 70% of the time, 0% pdr 30% of the time. So in above example, 10% or 0% PDR both possible (range 9716 ~ 12701).

Mathematically equivalent to option 1, just gives you a wider damage range.


This is what I suspected from work on Tespia (with a Hero) but didn't get to confirm cause the range was too large (plus combo orbs messed with data collection)

Only did a bit of testing, results are here:

TL;DR From what I saw, it's OP's first option.

I redid some tests as well and didn't happen to get the high maximum I got, so I'm guessing it's the first option also.

It's the first hypothesis, I can guarantee it. Another way to express it will be

(1 - PDrate) + (PDrate * (ignore defense total)), where ignore defense is additive. If your weapon has 15% ignore and you're a hero with max combat mastery, it'll be 55% defense ignore.

Yea I basically set mine up as [1 - (MobPDR * (1 - CharacterPDR))] which is a--in my mind--simplified and rearranged version of what you had.

Option 3:
30% ignore pdr = 100% pdr 70% of the time, 0% pdr 30% of the time. So in above example, 10% or 0% PDR both possible (range 9716 ~ 12701).

Combat Mastery makes no mention of requiring Combo? Why wouldn't you just use unbuffed normal attacks? Or Monster magnet? Low % modifier = Low damage spread. (Then again trunication, which maple is famous for, would increase the %error)

In a perfect world it would be additive. It's probably multiplicative such that you don't have a mob with 10% PDR taking 30% extra damage.

Oh what a lovely world that would be...

would it stacks together with 'Marksmanship' ?
Eg. 15% Ignore Def (from weapon) + 20% Defense Ignored (from marksmanship) = 35% ?
