Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is not an in depth guide. I'm posting this for those that know what there doing with a dps character or already own Irelea. Most builds just didn't have the attack speed that I felt was necessary for Irelea, most go tanky, not quite my play-style. Anyway leave a suggestion if you would, please. Let me know of your ideas because mine are far from perfect. This is also my first build I have posted so please take it easy on me. I will appreciate all constructive criticism.
Solid Attack Speed runes, I think this is the only way to build Irelea. Her basic lifesteal off of Hiten Styleis base 26 at level 5. This allows you to get your attack speed up without having to worry about lifesteal early game.
22/0/8 This allows you to max out your damage potential and get the xp boost off of the utilities list. This section is completely up to you though. My mentality is that if they are dead how can they hurt you? So I usually focus on as much damage output as possible. Tanking is up to the tank not the dps.
All right, on to one of the most important sections of a guide. I am a die hard attack speed fanatic. And to top it off this build is extremely expensive. And the key issue with these items is that there is absolutely no CC. Stuns and suppressions will ruin your day, every time. Unless you live through the stun/ suppress. If you do survive then they had better have brought friends because they will not be getting away once they have arrived.
I start with a Dagger because, as stated earlier, I am a die hard at... no need to repeat. I then farm to my Berserker's Greaves and hopefully have gotten a kill or 2 by this time. Either way B once you have enough money to buy your Greaves and another Dagger and your on your way to a Zeal. I get the Zeal for the extra movement speed and yet again more attack speed. After the Zeal, grab yet another Dagger and start saving for a B.F. Sword, you need that Black Cleaver. As soon as you have a Black Cleaver welcome to mid-game.
This is when you can start looking at other things than attack speed. Grab a Vampiric Scepter for yet more lifesteal, then start saving for another B.F. Sword, then onto your Bloodthirster. After this point the game is usually almost over, but occasionally the game persists. And that is usually because they have either really armour heavy tanks or really high health tanks. At this point it is allright to switch from the Stark's Fervor and grab an Infinity Edge or Madred's Bloodrazor. Lots of people swear by the Trinity Force but I think that it is completely all right to switch it out for a Phantom Dancer (more attack speed ;) booya!). The last 5 items I have listed are all situational items that I build.
Build Hiten Styleas fast as you can. This build does not work without that passive lifesteal, and the active is kick-*** for the lack of damage you have early game. After Hiten Styleyou will want your Equilibrium Strikefor the slow and stun duration to be maxed out. I have tried building Bladesurgebefore Equilibrium Strikeand it is not as useful. Put one rank into Bladsurgeso that you can jump to the enemy and then have fun.
I like to grab Ghostand Exhaust. Those are the most useful spells and are the most adaptable to any situation. Flashis a good alternative to Ghostbut after you have a Zeal no-one will be able to catch you when you pop Ghost.
Feel free to use Transcendent Bladesto farm large bubbles of minions. The cool down on this ability is very short, even at first level.
Sorry for the lack of images on the item section. I can not figure out how to get them there. As stated earlier I would appreciate any and all constructive criticism. Also stated earlier this is my first guide let me know how I did, thank you and enjoy the build.
