Hi, so Irelia? if you think some items or masteries or runes are not good dont rage or something like this, with build i'm gona show you now I always have good score and cuz of me we win.

I was reading some builds for Irelia and then i mix some runes and get this, it's not bad. This armor and health save my life few mayn times from ganks. Armor penetration is good cuz you will take more damage and it will be easier for you and harder for then cuz they know if they come closer to you they are dead. Magic resist if you are building tank u'll need it unless if they are all ad...

Nothing specialy for say but.. masteries can change your whole game and your champ so be carefull with fulling them.

I prefer to start with Regrowth Pendant, if you solo or with m8 start with Regrowth so u upgrade it in Philosopher's Stone. When u first time go back make sure u buy Boots of Speed and if you have enough gold buy boots and Philosopher. If enemy team dont have ap champ take ninja tabi or attack speed boots.Trinity cuz u move faster, attack harder and faster, have mana, slow target with phage and lots of abilities.. Warmog, if you tank her u need it , end of story, buy it after trinity... If you were asking where the fuq is armor and here it is: Atma's Impaler, good cuz u have armor and get critical chance and this items is like made for Irelia, Guardian, item is saying everything... and last item can it be Force of Nature or Phantom, your choice I take Force cuz u need magic resist but phantom is good too..

Bladesurge (Q) I max it first. So if you are farming try to kill the minions or monster's with this and your 35 mana i think will refund! Awesome skill

Hiten style (W) I max it second. Good item cuz you get damage and you are restoring health. Always use it when u go in team fight or 1v1 or something.

Equilibrium Strike (E) Maxing it last. If the target has a higher Health % than Irelia, then the blow stuns the target instead. If don't u just slow him but slow is better than nothing, this skill can save u many times from ganks.

Transcendent Blades (R) Throwing 4 blades which deals lot of damage and she heal 10%. And dont use ulti 3-4 times in game, use it almost in every situation.
