82% amor pen vs AD which is better?

Mflames·Sep 7, 2016·2 votes·1,022 views

With These to items on there own + + 7% from masteries, you get the following.

82% armor pen
100 ad + 1.5% per 50 hp difference.
300 hp
20% cd Cost is 5800 gold.

Normally Adc would get + which gives you

70 ad + 120 magic dmg
50% crit
5% move speed
35% attack speed For a cost of 6200 gold

Now my question is regardless who you attacking is 82% armor pen not more worth it, i mean 82% off of 200 armor or 60 armor is such a major thing. Armor -> whats left 60 -> 10.8 80 -> 14.4 120 -> 21.6 160 -> 28.8 300 -> 54

So can someone please give me their opinion, i mean it looks to me like all AD adc's should rush this? what you guys think

I think it doesn't work that way if you have 320 bonus armor, and black cleaver shreds 30% of that, there's 224 left. THEN LW and the mastery kicks in. that's 107 armor left.

That's closer to 66% bonus armor pen.

honestly all you need after IE and a Zeal item is lord dominik's regards and tanks aren't going to last long. there's no need to build cleaver on an ADC

Flat penetration occurs after % penetration.

When attacking, armor penetration and armor reduction are considered in the following order:

Armor reduction, flat
Armor reduction, percentage
Armor penetration, percentage
Armor penetration, flat Note: Base Armor and Bonus Armor are calculated separately.

So you saying in one MissFortune ulti wont apply the 45% and 30% ? which btw rank 3 with almost 150ad is 3000 dmg. with 82% would be great

MF's ult wouldn't do 82%, it'd shred 30% of their total armor and then ignore 52% of the 70% of the bonus armor that remains. The exact percentage is a little evasive at that point, but definitely way less than 82% unless you're Darius

More importantly, odds are for the first 15-20 minutes of the game, an ADC isn't going to be running into a lot of armor to penetrate. That's why LW items are usually built third or fourth

then ignore 52% of the 70% of the bonus armor that remains.

Lord dominiks is only applied on bonus armor, while the 7% mastery is total armor. so it'd be 52% bonus armor pen and 7% base armor pen.

TTK DreadnoughtSep 7, 20161 votes

No, it still applies, but it's how the application is done. Also, base armor and bonus armor are done separately

Both the 45% and 30% are applied, but in a certain order like mentioned below in another comment and re-posted here

Armor reduction, flat

Armor penetration, flat *Note: Base Armor and Bonus Armor are calculated separately.

Stats: 90 base armor, 320 bonus armor (410 total armor, 80% damage reduction) Step 2: 63 base, 224 bonus Step 3: 58.59 base, 107.52 bonus Remaining stats: 58.59 base, 107.52 bonus (166.11 total armor, 62.4% damage reduction) *About 41% total armor pen with 7% mastery, lord dominiks, and black cleaver

It all depends on your opposition. if you want to melt tanks, go pen, to burst squishies, go crit

TTK DreadnoughtSep 7, 20161 votes

With Lord Dominiks being an item, it doesnt matter whether the ADC builds pen or crit. We still melt.

Gary B EnkelisSep 7, 20161 votes

I think flat pen is good vs squishies because it brings them close to 0 which is like you doing true damage?

TTK DreadnoughtSep 7, 20161 votes

or just mix the two like what my friend does on GP.

item 3078 item 3142 item 3031

12 armor pen plus yoomus + maw = 42 flat reduction So if someone has 60 armor then Flat 60 -> 18 left Arm % 60 -> 11 left

Gary B EnkelisSep 7, 20161 votes

Oh yeah I meant to say reduction not just pen. Yeah, that's pretty good at getting close to true damage? And there's no hoping for a lucky crit.

item 3071 reduces total armor by 30% (at max stacks) while item 3036 reduces bonus armor by 45%, so if I'm not mistaken the sum from, BC + LDR + 7% from masteries isn't exactly 82% armor penetration.

Gary B EnkelisSep 7, 20161 votes

item 3035 and it's upgrades ( item 3036 item 3033 ) **penetrate ** armor. These items do not **reduce ** armor. There is a difference.

calculator 30+45+7 = 82. so how do you mean?

HigeSep 7, 20161 votes

reducing and penetrating are separate effects, reduction occurs first, so in the case you have 100 armor (for calc purposes) you reach 70 armor against a Black cleaver and then that 70 armor is penetrated by Last whisper/lord/mortal so 45% + 7% from masteries equals 52%

52% of 70 = 36.4 70 - 36.4 = 33.6

this is a total penetration/reduction of 66.4%

and just remembered that Last whisper/lord/mortal penetrates ONLY bonus armor, so it's even less...

TTK DreadnoughtSep 7, 20161 votes

even though Lord dominiks is only applied on bonus armor, the 7% mastery is total armor. so it'd be 52% bonus armor pen and 7% base armor pen since they are calculated seperately

HigeSep 7, 20161 votes

true true!

ItsOrvalSep 7, 20161 votes

Dont buy bc with Last whisper... Ever.

Gary B EnkelisSep 7, 20161 votes

item 3071 reduces armor, which is different from penetrating armor ( item 3036 ).

Armor reduction applies to your team / other sources of damage and flat reduction can bring them below 0. Reduction actually reduces their armor, as far as I know.

Armor penetration applies to you and is capped when they reach 0 armor...

I think. It's confusing.
