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.
First of all, this build is what I use that fits my play-style.
And for those struggling Irelia users, feel free to try this out.
AP nukers from your team would really love to stick with you in this build.
Because of that Malady ^^
I always go for the items in this order:
Zerker boots -> malady/madred's razor -> malady/madred's razor -> Sword of the divine -> Madrerd's Bloodrazor -> Guardian Angel -> Usually the game ends before i can make a 6th item. So this last item would be something to fit the situation.
With this build Irelia will be a very fast DPSer with Damage from Malady, Bloodrazor's & Sword of the divine.
And with that fast ASPD/Magic Dmg from items/True Dmg & Heal per attack from Hiten Style you'll be able to survive and deal damage in team fights provided that your team is doing well. And has a good tank.
Yes Irelia is squishy if she gets focused so until you have your GA stay behind your team and go in like your playing master yi.
As for the 6th/last item.
Here are some suggestions:
Wit's End - Burns your enemies mana per hit and turns that into bonus damage, gives good ASPD also.
Abyssal Scepter - Gives AP... yeah not much but that MR and MR reduction aura will proc with your magic damage dealing items. YES, MR redux/MPEN does affect magic damage from items.
Banshee's Veil - Good survivability item.
Yumuu's Ghostblade - Nice.
Phage - Survivability and slow. If you feel the need to chase/flee.
Rylai's Crystal Scepter - Not sure lol.
Stark's Fervor - IF you pick this as your last item then you probably have won the game. YOU'RE FED!
KSING! IMO is not good when playing as Irelia :/
-That's Pretty Much IT-
