So how does armor / MR work?

Niyumi··3 votes·604 views

Title. ADCs are typically the worst offenders (not counting Last Whisper and whatnot, just a full AD ADC with not one bit of armor pen on them).

But, say I have a shit ton of armor, and I'm taking 73% reduced phsyical damage as well as a flat 12% reduction from Ninja Tabi (85% together). Yasuo, Cait, Jhin, Kha, or some other AD champ just strolls along and does 500-600 damage to me repeatedly -- or even more.

Now, I'm no mathematician, but if 500-600 damage is 15% (27% in Kha's case) of something... are they hitting for over 3700 a hit before mitigation? I don't think that's realistic, so does the game lie about how armor works, or what's the deal?

I assume it's just

Damage = Raw Damage * Armor % value (So, X * .15 in this case)

Is that wrong?

EDIT: So, after reading that wiki and even going so far as to plug in numbers, yeah, apparently Yasuo and Cait auto for ~3800 an auto. Guess Riot lied about how armor works, or are autos just that absurdly broken?

So, yeah, damage is multiplied by a percent.

So then, if 500 is 15% of a value, then that means Yasuo and Cait are autoing for upwards of 3800 an auto?

no the deal here is that there are first. a bunch of masteries that give % damage.

two ldr gives bonus damage depending on how much hp you have.

depending on how many infernals they have. an adc auto (with no modifiers) deals about ~800 damage on crit with 6 items. cait has headshot which scales ridiculously well dealing upwards of 1.5k damage on a headshot. draven does like 1.2k damage with his Q and jhin does similar damage on his autos. yasuo deals similar amounts of damage. he does less damage on crits but its negligible since he gets crit quicker he can simply invest in more ad items than crit.. and most ad carries get 70-80 crit at most. some even 50%. yasuo has more dps.

3800 an auto is ridiculous unless your jhin and he autoed you while you have really low hp.

mathematically its possible for an ad carry to do about ~1k damage on crits.

tldr: ignore all of the numbers basically when an adc has lord dominks or your fighting a yasuo your gonna die really fast. or an adc like jinx can kill tanks really quick even without ldr because she stacks a lot of attack speed.

Everything in here should answer your question.

Okay, I know reading comprehension isn't really a thing anymore, but I specifically said without armor pen. You know, someone like Yasuo just stacking AD? Or Kha? Or an ADC going for the one-shot? Yeah.

You could of simply moved on or stated it wasn't the info you're looking for. Nope. You need to be a smart mouthed dick.

Spit on enough people who try to help you and one day when you'll truly do need help, you won't receive any and then you'll wonder why. Avoid doing it in the future even if there happened to be a miscommunication in the process along the way. Anyways now you have both info, read up on them, you should have your answers.

basically the way it works is that EVERY POINT of amor/mr gives you 1% extra health against that particular damage type

the way to calculate how much damage reduction you get from armor is simple

100 / (100+armor)= damage reduction

so lets say you have 100 armor

you do the following 100/200=0.5 so their total damage gets mulitplied by 0.5 so 1000 damage becomes 500. if you have lets say 350 armor

its 100/ 450 = 0.22

as a general rule of thumb item 3143 gives the most amount of "effective health" against anyone that does physical damage before an item such as item 3110 becomes more efficient against physical damage is roughly around 3.5~3.6k health i believe. in general item 3102 is the best all round item against magic damage item 3065 is a close second but if your champion has sustain in his kit or with its build it becomes the number 1 item to buy XinZhao Udyr Alistar Irelia Darius are all champs that should build it

Nautilus Blitzcrank Rammus Braum Leona Nautilus are examples of champs that should build item 3102 whenever they need tons of protection from magic damage.
