Blade of the Ruined King is your biggest core item, becouse it gives the perfect stats for Irelia (AD, Lifesteal, Attack speed). Its first passive works very well with her too, the HP% dmg on-hit synergies very well with her high attack speed and Q. Its second passive is pretty good too, making your 3rd attack slow, and gives you movement speed. With this item you can easily kill tanks, and chase enemies down, while staying alive becouse of the lifesteal. Buy this item first.


Trinity Force Is another powerspike for Irelia, her mythic, which is pretty expensive. To get this item as fast as you can, try to CS much on your lane, dont miss any last hit with your AA or Q (requiers a little practice). This item gives good stats, but not as good as Blade of the Ruined King. Trinity Force Gives you some HP, little AD, a big amount of attack speed, and Ability Haste. Ability Haste is good, but Irelia doesnt really rely on it. The best thing in this item is its passive. The first passive is similar to the Blade of the Ruined King second passive, becouse this gives you chasing potential too. The second passive increases your dmg by 30% (6% for each AA) and is really good, but its not really noticeable in the game. The third passive is why this is a powerspike for Irelia. When you use a skill, your next AA deals 200% dmg. This means your Q will deal more than 2x dmg (Becouse it applies on-hit effects), and with this you can Q caster minions anytime, when you have this passive effect (this has 1.5 sec CD)


You should buy Wit's End only if there is at least one AP carry in the enemy ( Ekko, Katarina, Fizz, Ahri, Neeko, etc...). This item is very good against AP enemies, it gives you 50 magic resist. Wit's End also gives 40% Attack speed, which is huge, and a bit of attack dmg. The on-hit effect passive makes Irelia Q, and fast AAs even scarier, and the 20 movement speed bonus on-hit makes it even easier to catch people. If you buy Blade of the Ruined King, Trinity Force and Wit's End too, you will get 45 movement speed for your AAs and if you manage to hit 3 AAs you will get bonus 25% movement speed. With these movement bonuses, you can catch almost everyone with dashes and Flash ( Nidalee, Qiyana, LeBlanc etc...)


Death's Dance is an item that gives 40 Armor, 50 AD, and 15 Ability Haste. The Armor is good aganist Attack Damage Carries, so buy this, if you fell like they are strong in the enemy. The 50 AD is good, but Irelia's skills arent really scaling with AD. 15 Ability Haste is not the best for Irelia, but its good to have. This item's passive is what makes it really good. The passive makes you survive longer in all ins, and if you manage to kill, it heals you and gives you a good amount of movement speed for 2 seconds, so you can either escape, or chase other enemies down.


Sterak's Gage gives good stats, 50 AD, 400 HP. Hp Helps you survive longer, and AD makes your AA's stronger. This Item's first passive is not really noticeable, Heals you slowly if you take, or deal damage to an enemy champion, and can stack up to 5 times. The second passive gives you (200+8/16/24/32/40% depending on the first passive stack) shield for 5 seconds. This can help you survive even longer.


Titanic Hydra Is a well scaling Item, that gives you a HP% based on-hit Aoe dmg. It gives you 30 AD and 500 HP. Its first passive gives you AD based on your Max HP 1%. If you have 3000 HP, you will get a bonus 30 AD. The other passive is a on-hit Dmg (5+1,5% Max HP example: 3000 HP, 50 on-hit Dmg), and a Aoe dmg (40+3% Max HP, example: 3000 HP, 130 Aoe Dmg). These passives makes this item scale well with other HP items ( Sterak's Gage, Trinity Force).
