armor pen

magic pen

For starters Nobody builds . The reason for this is that it deals % of their current health which basically means it cannot kill anything. You can have 1 health left and this item wont kill you. Therefore it is basically useless. Mundo can litterally heal through any damage it does and he is the only champion where you would want this item but then again why would you build it when everything else is better.

is just crazy good. it gives a passive that you dont have to activate therefore it requires no additional skill of the player. This item you dont even have to think about it if you are playing as an ad assassin you just build it because its op

is super cheap

Your post was very well-thought and demonstrated a deep understanding of the game. More boards members should strive to make posts like yours that go into detail as much as you did. I feel as if I'm now an expert on armor and magic penetrations and why... wait, what's your point in the first place? What's your argument?

most ranged champions have 30 base mr and get maybe 20 more with runes.

you already almost deal true damage with sorc boots and abyssal. how much flat pen do you need?

item 3151

deals 2% of max hp but double if slowed or movement impaired

assuming it does 4% it will deal 4% per second with some diminishing returns.

100 - 4% is 96 96-4% is 92.16

after 2 iterations it goes from 4% to 7.84%. The second tick was 3.84% of max hp which is .96 of of 4%

so each will reduce 4% less of max hp

So 3 ticks will deal 4% + 4% - 4%^2 + 4% - 4%^3 = .04 + .04 - .04^2 + .04 - .04^3 = 0.118336 or about 11-12% of his hp as magic damage over 3 seconds regardless of how much damage you actually dealt.

This makes it possible to deal more by building penetration which will give you lower AP values but more utility from AP itemization. Btw nobody builds things like liandries because enemy teams aren't usually that tanky. Imagine 11% off of 4-5 champs with nothing more than poke. You can literally chunk off their bonus hp items essentially before the fight which is what elise used to do in teamfights while being too tanky for most champs to deal with.

Actually I see item 3151 gets some play now because item 3116 is so ~~broken~~ popular Malzahar

But without Rylias Liandires is very situational; perhaps some power needs to shift from rylias to liandries. (I think a minimum burn which can kill would go a LONG LONG way for player purchase satisfaction)

Torment can sometimes be ok though if the enemy is bad and has no MR on their 30 items (6 across 5 champs lol), just for the sake of flat pen. But then again I coulda bought a Lichbane instead here Anivia item 3027 item 3040 item 3020 item 3089 item 3151 item 3157 (they basically built no MR lol)

item 3151 on a teemo makes his shrooms more deadly. It's good for poking.

If mundo can heal through it, then that's mundo and not the other hundred something champions there are in the game.

u wot I build item 3116 item 3001 item 3151 almost every game. makes you super tanky with tons of damage with all the flat pen. Your enemy doesn't even need to stack health for liandry's to be good.
