Ignore PDR vs 30% boss dmg on weapon

Was wondering which is better for bossing post bb mathematically, in terms of dmg, say for a wh,bam,bm,corsairs, mechanics, warriors.

Say base def% is PDR. eg. 0.25 for a lot of bosses.

Then you have
(1-PDR)*1.3 -> 30% bossing
(1-(PDR*0.7)) -> 30% ignore def
Solving for PDR where these are equal,
1.3 - 1.3*PDR = 1 - 0.7*PDR
0.3 = 0.6*PDR
PDR = 0.5
As PDR increases, 30% ignore def gets better, so for greater than 50% def, it's better to have 30% ignore target def.

If your class already ignores some % def, call this SD (SD <= 70% otherwise there are issues with this method - mostly that 30% bossing is always better)
(1-PDR*(1-SD))*1.3
(1-PDR*(0.7-SD))
1.3 - PDR*1.3 + 1.3*PDR*SD = 1 - PDR*0.7 + PDR*SD
0.3 + 0.3*PDR*SD = 0.6*PDR
0.3 = 0.6*(1-0.5*SD)*PDR
1 = (2-SD)*PDR

So eg. if SD = 0.4 (heroes), 1 = (1.6)*PDR -> 62.5% def is the minimum before ignore def is better.

Hi thanks for your reply, so essentially, if one is going pink bean weekly to farm mw30 then a ignore 30 will beat a bossing 30 flat.

Is there a list for pdr of bosses, I remember seeing someone compiling them.

50% for major bosses (Zak/HT)
75% for PB
25% for pap and such.

This is all of memory though... someone find that thread xD

40% for Zak/HT
50% for Chaos Zak/HT
25% for Pap
70% for Empress Cygnus and Pink Bean.

Ho lols was I off on a few xD

But I got pap right hells yeah :O

Anyone wanna translate this to English for me please? ty <3

Let us define the base mob def% to be PDR. eg. 0.4 for Zakum

Damage multiplier when equipped with a weapon with 30% boss dmg is 1.3
Damage multiplier when attacking a boss with PDR is 1-PDR

Total Multiplier when equipped with a weapon that does 30% boss damage is
(1-PDR)*1.3 -> 30% bossing

Similarly,

Total Multiplier when equipped with a weapon that ignores 30% boss pdr reduction is
(1-(PDR*0.7))

* I am still wondering about (1-(PDR-0.3)) as compared to (1-(PDR*0.7))


Solving for PDR where these are equal,
1.3 - 1.3*PDR = 1 - 0.7*PDR
0.3 = 0.6*PDR
PDR = 0.5

As PDR increases, 30% ignore def gets better, so for greater than 50% def, it's better to have 30% ignore target def.
( In this case Chaos ht, Chaos zak, pink bean and cygnus would satisfy this equation)


If your class already ignores some % def, call this SD (for example hero's enrage has sd 0.4) (SD <= 70% otherwise there are issues with this method - mostly that 30% bossing is always better)

Total multiplier with class sd and 30% boss damage would gives
(1-PDR*(1-SD))*1.3

Total multiplier with class sd and ignore mob 30% pdr gives
(1-PDR*(0.7-SD))

Solving these 2 to find a relationship between pdr and sd

1.3 - PDR*1.3 + 1.3*PDR*SD = 1 - PDR*0.7 + PDR*SD
0.3 + 0.3*PDR*SD = 0.6*PDR
0.3 = 0.6*(1-0.5*SD)*PDR
1 = (2-SD)*PDR

So eg. if SD = 0.4 (heroes), 1 = (1.6)*PDR -> 62.5% def is the minimum before ignore def is better.

If we have threaten then it would have

total sd = 0.61 1= (1.39)PDR => PDR = 0.71 , so a pdr of 71% would be needed to be better than a 30% boss dmg weapon

what happens if sd = 0.2 for archers, then we have 1 = 1.8 PDR => 55% PDR and above would be needed for a ignore weapon 30 to be better.

Imagine going up against zak with 40% PDrate. This means you'll be doing 60% of your damage if you have no base ignore PDrate.

Boss +30% lands you at 60x1.3= 78% damage.

If you choose to use 30% ignore, then you'll ignore 30% of 40 which is 12. so the boss will have 40-12 PDrate aka 28% PDrate. Meaning that you'll do 72% of your possible damage.

So in this case, boss 30 wins.

~~~~~~~~~~~~~~~~

The only time ignore 30 beats boss 30 is (after your base calculations are done) you are dealing 50% or less damage.

Examples:
1) Corsair (no base ignore PDrate) at chaos zak/ht and PB. They'll be doing 50% damage at the first two and only 30% damage to PB. At 50% damage, boss 30 will be the same boost as ignore 30 (but ignore 30 also works on non bosses too). At less than 50%, ignore 30 beats boss 30.

2) Hero's have 40% base ignore. So against chaos zak (which has 50 PDrate) they'll ignore 40% aka .4*50 = 20. So they'll ignore 20 of it (aka lowering zak's PDrate to 30). So overall they'll be doing 70% of their damage to chaos zak. So they should stick to 30% boss.

It seems like ignore def gives one (the person) to deal higher true damage aka Armor Penetration?
Do you guys think that...

1) 15% Ignore Def > Total Dmg 8% ?
2) 15% Ignore Def > Attacks 9% ?

1) 15% Ignore Def > Total Dmg 8% ?
2) 15% Ignore Def > Attacks 9% ?

Assuming you don't have any kind of "ignore DEF" skill:

1 and 2) If PDRate >= 40, yes. Else, no.

1 and 2) If PDRate >= 50, yes. Else, no.

o_o same calculation and effect with 30% boss dmg?
I see

Yeah, the math is pretty much the same (PRDate * (1 - Ignore Def)). I miscalculated the result, however

Edited the post to fix it.
