do they stack? if yes that mean you have 32% damage reduction against the target you are hitting that disgusting if this actually exist riot really need to gut PD because i was playing Yi with this 2 items and seriously they didnt no damage to me i dont know if it was PD or the red Smite or both of them but it was disgusting and i abuse it but this need to stop
Atanchan3 votesPhantom Dancer reduces damage you take from your attack target to 88% ( 100% - 12% ).
Challenging Smite reduces damage you take from the target to 80% ( 100% - 20% ).
88% of 80% is 70.4%, which then means 29.6% damage reduction, not 32%. Stuff like this basically never stacks additively, because not only does that mean that it all has to be tracked in a way that the game could gather it all before applying any damage reduction, it'd allow for damage reduction below 100% to reach 100% if you have enough of it.
If you're wondering, this means that with Ninja Tabi and PD on a target you're both attacking and used Challenging Smite on, you're taking 61.952% damage from them, or have 38.048% damage reduction. Or, y'know, 62 armor.
Y'know. Less than Gnar has at level 18. And he's the champion with the lowest armor growth in the game, besides Thresh ... who literally doesn't have armor growth.
Merkel x Tsipras1 votes38% damage reductions FROM ALL SOURCES OF DAMAGE
So you know 62 armor + 62 MR
provide 40 mr for 800g
provide 40 armor for 800g
So you dont have the 62 armor and mr but lets say you buy 
for 2700G to have 55 armor and MR
Now you have an 2700 defensive item on yi or graves which mean nothing....
But now you have 40% damage reduction from OFFENSIVE items and you reduce for 40% the damage you take from all sources
Plus the 40% damage now apply before ressistances so your ressistance alone will have you 30-40% damage reduction plus the 40% (which dosent stack additevely but they stack) you know have almost 55-60% damage reduction from all sources BY BUILDING OFFENSIVE ITEMS
And we see no problem with that?
67chrome1 votes38% damage reductions FROM ALL SOURCES OF DAMAGE
It's only 38% damage reduction from physical and magical damage, which isn't all sources of damage.
%Damage Reductions don't effect True Damage, because the entire point of True Damage is that it isn't effected by %damage reductions.
Atanchan1 votes42 MR. Ninja Tabi's damage reduction only applies to autoattacks, which, under most circumstances, only affects physical damage. So you're only benefiting from the 29.6% damage reduction from PD and Red Smite.
Which ... means you need less that a Null-Magic Mantle to match that damage reduction.
So by grabbing Ninja Tabi and Null-Magic Mantle on anyone but Thresh, you'll reach a greater amount of damage reduction Ninja Tabi + PD + Challenging Smite far earlier, for far less gold, against every enemy.
So, yeah, considering that offensive AD champs are not barred from getting defensive stats ( hell, they're the only ones that can even use lifesteal well in the first place ), this seems like perfectly acceptable amounts of bulk stats on items that provide both them and offensive ones, especially considering they're all extremely conditional bulk stats. PD only works on your attack target, Challenging Smite requires you to take Smite and only works on your Smite target, and Tabi only works on autoattacks.
Remember, you can buy anything that builds out of Cloth Armor to get the same amount of damage resistance against autoattacks ( and physical damage in general ) from literally all enemies, after a few levels on anyone that isn't Thresh.
It's worth remembering that all the conditions? They're basically all dueling conditions. Literally all these defenses vanish as soon as the guy jumps on one on your teammates and your AP blows their load on them - which is only mitigated by their base stats now, because PD and Challenging Smite are only affecting the damage from the guy that just got jumped on, and Ninja Tabi does absolutely nothing against magic damage ability users.
So, yeah. If there's two things that you should take from this, it's to always make sure your team comp has worthwhile magic damage, and to not try to 1v1 the guy who's literally itemizing entirely around being unable to be fought 1v1.
Marshbouy2 votesI think so. that's part of the reason why graves get's red smite.
Merkel x Tsipras1 votesso you have 
that mean you have 44% damage reduction from AA and 32% damage reduction from all source of damage? Yeah that retarded if that actually a case its retarded and add bone of mastery from your support we talk about 50% damage reduction from AA and 38% from all source of damage!!....
Marshbouy1 votesI think so yeah. (dont forget 
)
CerealBoxOfDoom1 votesI see no issue if you have to give up so much to get the reduction.
UberAffe2 voteswhat are you giving up? the jungle item gives % max health damage on hit along with true damage from the smite and that is a ton of attack speed
CerealBoxOfDoom1 votes
You don't get the slow so you can more easily be kited
You don't get vision
You don't get tenacity
You become reliant on attack speed so 
but then the scary part is that theres a reasonable ult level cooldown on all of this. Whoever gets smited can't do much but everyone else can. Basically you have a yi who can 1v1 really hard but can't teamfight. Which is the traditional weakness of melee carries, they've never been viable when these were their strengths.
But then lets go further.
None of the items built except tabi will help you against assassins and ninja tabi wont help very much. And this just does like nothing for you vs a mage who will lock you down and blow you up even if you do manage to get in range to smite them. Even then they can 
to screw you over.
You also have to take smite to use this and it deals close to the amount of damage 
would do but comes from an item that tends to be sub par and wont scale well into the lategame.
UberAffe1 votesoh no a build has a counter build ... that doesn't make it a bad build, it makes it situational. If the enemy team only has one or two people who are a threat then this might be a great option.
Ult level cd? Sure it has a 75 second recharge time but it also can have two charges with only a 15 second delay, that can easily be used twice in one fight.
CerealBoxOfDoom1 voteswell outside of the counterbuilding that still leaves you with another 12 lines of weaknesses lol.
By the way that's already 2 items without lifesteal, neither is an actual heavy damage item and the defense is actually very meager.
2625g
2550g
1100g
you claim this is 44% damage reduction against autoattacks but this costs a total of 6275g
44% damage reduction = a damage modifier of 56% or .56
.56 = 100/(100+armor)
100 + armor = 100/.56
armor = 100/.56 - 100 = 78.5714285714 or 79 armor
= 40 armor for 800g
for 1600g I can get a little bit over the same damage reduction and still have 4675g left to build with.
Merkel x Tsipras1 votesAlistart ulti with no armor and full AP items at his lvl 3 ulti can have 70% damage reduction WHICH mean he reduce ANY source of damage (except true damage) by 70%
So no its not the same as buying 100 armor because i can have 100 armor and trust me i would not tank a target as an alistar with his ulti on (lets say an AD attacking you not magic damage because we talk about armor)
So the 50% that this 3 items provide is way more than 800g value 50% damage reduction from ALL sources mean that now you have if we go with your example 200 armor and 200 mr
Good luck finding that much of ressistances for 800g!!
And btw a Yi building those items and having 50% reduction mean that now you have your own reduction from your base mr and armor plus the 50%
And all that for 3 OFFENSIVE items not defensive and you see no problem withthat ok cool
CerealBoxOfDoom1 votesits not 800g, its 1600g. To get the same amount of defense he's paying an extra 4675g. he's paying nearly 4 times as much for the thing you were originally complaining about.
Aside from this he's getting
0 AD 95% attack speed 30% crit chance and an ignite effect...
He's also getting 4% of your max hp per autoattack as physical damage.
offensively there's also nothing special about it considering a price tag of 6275g for budget items that are going to fall off lategame.

that's 70% on top of his already high tank stats
alistar hp = 613-2415
alistar armor = 24.4-83.9
master yi hp = 599-2163
master yi armor = 24-75
master yi also isnt typically going to be taking resolve masteries. master yi doenst stop you from dealing damage for a long time with CC master yi's heal doesn't allow him to keep moving and isn't instant except a small bit at the start I think thus making it harder to notice. AP alistar will heal for enough to make him appear to be tanking a lot more than normal.
UberAffe1 votesYea, you probably wouldn't want to rush these 3 before getting anything else. Don't forget that armor also losses effectiveness the more you have. If you built a damage item and armor item and an mr item as your other 3 items, probably getting pd as 4th or 5th item you could around 81% damage reduction on autos. Lets say you build something like this:
30 armor 10% reduction on autos from tabi
90 armor from frozen heart
15% delayed damage from death dance
12% total damage reduction from your target from pd
35 mr from mercurial
20% damage reduction from your target from red smite
That makes 110 armor for 47% reduction with another 10% reduction on autos 35 mr for 26% reduction 32% reduction from all damage that comes from your target 15% delayed damage
If your target is an ad auto attacker you reduce their auto damage by 68% their ad based abilities by 64% and their ap based abilities by 50%
After breaking it down with math Merc tread would probably be better than tabi's but again that depends on the who on the enemy team is the problem.
CerealBoxOfDoom1 votesI.e don't be the first thing master yi targets if you have no defensive capabilities, no extremely strong offense, and want to kill him.
Yi is a duelist nothing new under the sun
