With Irelia you can be a long-time laner with the second ability(Hiten Style-W).And with the Q skill(Bladesurge)you can farm very easily the minion waves.And when you got your ultimate you can fill you hp right away if you use it on a wave of minions because it has short cooldown even for lvl 1 or 2 ultimate

Irelia is a very good ganker even at low levels because she has her charge and slow/stun.You can activate Hiten-Style then dive in with Bladesurge and then instant slow them with Equilibrum-Strike and if you think they will get away or if you are low hp you can use your ultimate to survive/kill.

Irelia is very good at harrasing/killing low hp champions between levels 1-4 like Malzahar,Ashe,Teemo etc. (after level 4 you can use your whole combo versus any type of hero because the combo>>activate W(Hiten Style)-dive with Q(Bladesurge)-slow/stun E(Equilibrum Strike).

In the teamfights with Irelia you must go in their support and then their DPS-es that can be took out right away with the usuall skill combo W-Q-E-R.Irelia is a very good champion in late game if you got the build i made for her because you will have spell-vamp and lifesteal that is very important and with the Guardian-Angel you can get back in the fight if you got nuked.

If an enemy champion is running with low HP near an enemy wave of minions you can charge on a low hp minion and then charge the champion and kill him because as you all know if you kill a taget with the Bladesurge the cooldown refreshes.

With Irelia you can easily stay on lane with low hp if you have your stun and ultimate because if you catch the champion in your wave of minions you can stun and use your ult on him and on his minons to get more hp and you can get him down.

This is my own build on Irelia and i can say that is really cool because you can beat 2 or 3 champions with the spell vamp and lifesteal in mid/late game.Irelia is a strong champion that i like to play with this build.And i didn't KS at all because with this build you have burst dmg.Also i will add some new screenshots as soon as i can :D

Hope you will enjoy pwning with this build!!! :)
