Hello to everyone , Im new here so this is my first build. I've been playing Irelia for a while now and trying to figure out how to play her well. She's a very hard character to learn and an even harder one to master. I'm not saying this build will make you a unstoppable Rambo 1 v 5 killing machine. But it does rape 1v1 pretty good. Irelia's role is to focus on one character and disabling him as fast as possible. So I play her a lot like an assassin : in / out. Enough Gab ..... lets see this build now.

Pros:
Very high damage earlygame
Stun is a surprise everytime to enemies
good jungler
hi burst damage + True damage bonus
Hard to slow cause of passive.
EXCEPTIONAL Minion Farmer

Cons
TEAM DEPENDANT
Item dependant
Kinda squishy
HARD TO PLAY WELL

For runes I got a mix of DPS and Caster Runes.for the basic damage penetrationfor a little more health in early game since you won't be taking a Doran's SheildThis is what makes a difference because you will be spamming your abilities.just more help to spam those abilities.
Alittle help to get that damage through.

Just basic Damage masteries and defense masteries ... nothing special there. I've tried going defense but it doesn't feel right. missing some punch to it you know. but i guess this is up to you.

Ok this here ... RIGHT HERE is really important.
Since she is item dependent you will need to rush a few of these but it should not be a problem since she is really good at farming minions.

First off when you start you want to getand a. The tome helps for theand you will be closer to thethat you need so MUCH . The rest of the items you fallow this order of the build , help gank around and Most importantly .... SPAM YOUR ULTIMATE . It's on a very short cooldown and takes down a whole wave of minons on lvl 7. and you can activate Sheen on EVERY BLADE of your ulti so It will hurt if you Auto attack between each hit. The other Item that is now very good is aBecause it give you attack speed.

This is the other part thats important, you want to play with teammate that can separate the other team if they bundle up. Like BLitzcrank , Janna , Alistar. or very Hi-Dps Disables , like Xin or Ryse. some tank/stun are good to : Sion, Taric. You can lane with pretty much anyone but it will be harder if you go with a WarWick(before lvl 6) , Caitlyn, or anyone that doesn't have any Crowd Control.

Well this is it, Good luck and remember why you are there. you need to get the important enemies out quickly and back out and come back for the rest. you play assassin-like and try not to die to much and you should do fine.Good luck
