Armor. I get it. but a lot of times. people say " buy thornmail and the adc will kill himself iif you get enough armor" this ashe in my game has only lifesteal from BORK. and I had 412 armor. and she didn't even lose health as I noticed. can you buff this please.I mean we're not asking for something that will kill him. just reduce their health. or sustain at least.
Ichinose3 votesThornmail is for poor tanks which think it'll save themselves from a fed Vayne.
But they don't know Thornmail can be easily countered with 
+ 
.

MR, AD & Lifesteal..
But if you're yet having trouble somehow you can get a 
, so you can heal from your abilities as well, making thornmail useless.

EndlessSorcerer2 votesThornmail is primarily meant to negate lifesteal so that autoattackers can't just heal through your damage. It is not meant to kill them through the reflected damage (unless you have a lot of armor).
If you want it to reflect more damage than you take, get more armor. Thornmail is meant to be a secondary or tertiary armor item for most champions (excluding Rammus and Thresh) instead of your sole armor item.
The Poetic Zed1 votesI think thorn mail is meant to reduce their life steal mostly. It's also extremely effective against kogmaw, because he relies more on AS than AD. Also, it's better for tanks like rammus, or taric, the tankiest of tanks i guess you could say. It's not great if you're going to be bursted down quickly, so the tankier you are, the more efficient thorn mail is.

cuddlykitten41 votesIt's meant as a combo stack for armor mostly. Lifesteal gains percentage of damage done, whereas thornmail's passive occurs before armor reduction. Also, you shouldn't take it just because of an ADC. It's more effective against teams with multiple AA reliant champs. Say they have Vayne, Tryndamere, Yi, Sona, and Yasuo. Other than the Sona that team is basically thorn damage material. It only returns a third of the damage but that means you only have to make up two thirds of what's left to run even. If they do 100 damage per AA (for the sake of simple math) they will take 30 damage in return. Let's say you reduce it by 50 with your armor. They still take the 30 damage but you only have to do 21 damage per their AA to make progress. If you have thornmail it's easy to assume that you have more health because you are most likely a tank therefore making this an advantageous trade. Personally I like to combo it with Sunfire Cape. Thornmail is usually not an every game item (unless you have a taunt) but it's one of the best situational tank items. It's just a matter of how you use it. I hope this was at least a little informative, and will help you in making the decision of whether or not to buy it each game.
Dreadlocks1 votesLooking at your match history, she also had a BT :)
DeathBurst1 votesOnly BtrK versus 412 armor, i don't have time to do the maths myself right now, but I don't believe it.
