Void Staff Doubt:

Nekusen·Jun 28, 2016·1 votes·406 views

Does it:

A) if you have 10 M.pen it makes it 13.5

B) if the target has 100 MR, it now has 65MR

C) if the target reduces magic damage by 50%, it now reduces it by 15%

Thanks.

Basically it reduces your targets magic resost by 33%

so, because the logarithmic way in which MR works, wouldn't this mean item 3135 becomes bad if the target stacked a crap-ton of MR ?

No it makes it better than flat magic pen

its the opposite

it becomes bad if the opponent has NOT stacked a shit ton of MR

sorcerers shoes do 15 penetration as does liandry's

so lets go with 30 flat vs 35% penetration

against the standard 30 MR on a ranged champion.. lets say 42 cuz runes or whatever

you deal 1000 damage

so 1000 * 100/(100+42MR) = 704.23 damage without penetration

with 30 flat penetration its 1000 * 100/(100+42MR - 30) = 892.857142857

with 35% penetration its 1000 * 100/(100+42MR - (42*.35)) = 785.545954438

but then lets look at this

30 is 35% of what

x * .35 = 30

30/.35 = x

x = 85.7142857143

so if you have 30 penetration then you are better off with 35% penetration if they have 85.7142857143 or more MR or you are getting your money's worth as long as your target has this amount of magic resist.

for just sorcerers shoes its

x * .35 = 15

15 / .35 = x

x = 42.8571428571

this is half of the other number so the amount of penetration you'll want on your next item is a simple thing to calculate for the most part. If you have to choose between 35% and 15 penetration then check to see if they have at least 43 magic resist... probably works for every 43 magic resist they have too actually.

% penetration is counted before flat penetration during damage calculations by the way so if they have 100 MR and you have 35% + 15 flat then you will penetrate 35 + 15 = 50 magic resistance.

hmm, actually, it would seem the damage is always increased by 10%

**at 100 MR: ** 100/200 = 50% resist - (voidstaff) 100/165 = 40% resist

at 200 MR 100/300 = 66.66 % resist - (voidstaff) 100/230 = 56% resist

so if you have 30 penetration then you are better off with 35% penetration if they have 85.7142857143 or more MR or you are getting your money's worth as long as your target has this amount of magic resist.

i kinda reached that conclusion, i think around 90 MR is when void staff becomes better than 30 flat pen, then it varies depending on runes and masteries.

thanks.

I believe the order of pen is:

item 3001 Reduction

item 3135 % Penetration

item 3020 item 3151 Flat Penetration

Examples:

If you had all four items versus an opponent with 150 MR...

150 is reduced by 25 from Abyssal Scepter to 125 MR 125 x 0.65 = 81.25 MR (From % Pen) 81.25 - 15 - 15 = 51.25 MR

If you had Void Staff, Sorcerer's Shoes, and Liandry's Torment:

150 x 0.65 = 97.5 97.5 - 15 - 15 = 67.5 MR

I believe that is how it works.

???? do you even know what % and magic pen is?

do you even know what a "doubt" is ?

item 3135 text reads "+ 35% magic penetration" Which by that, it would mean it increases your M.pen, which doesn't seem to be the case, it's a bad tooltip.
