Introduction
Hi guys I'm here to talk about one of my favourite champ
Irelia. I love Irelia for 3 reasons 1º she reminds me of Erza Scarlet from anime fairy tail; 2º she has some nice stats at mid game phase and 3º Irelia its a walking blender even built tank or full AD.From the first time I ever played I totally loved her she is able to solo top with no problem; Able to chase down enemys stick to them and chop them to pieces like a boss.
This guide its not complete I will upgrade it as soon as I can so sometimes come check the guide.

Farming and Invade Jungle
During your solotop laning phase, you should always invade the enemy jungle when possible. This means don't invade, if there is a wave of minions you should be farming on instead. Instead invade if you pushed your minion waves up to the enemy tower and there isn't really a way to get the enemy minions behind.
If you are at blue side invade the enemy small golems as often as possible. If you are at purple side invade the enemy wolves as often as possible. Even if the enemy jungler already took the camp, you can reset your timer to invade next time. Remember that wolves and small golems spawn every 1 minute. This will give the enemy jungler a harder time (if there is one) and give you even more farms if you manage this invading system well. If the enemy jungler is ganking bot lane, it is a good idea to invade during this time to. This will usually give you enough time to even steal their red or blue buff. Just be careful if the enemy team is smart, they may send their solotoper or caster to come and gank you. Remember not to invade if you have a creep wave coming though.
After getting some items, I'd say the red buff would be the better one to get from your jungler. Obviously it is a good idea to ask for the buff. Even if you have a
Trinity Force, that little passive damage from the red buff will still benefit you greatly in fights and farming. If you only have a
Phage, this buff will make sure your opponent gets slowed. If you have an AD carry nearby, you should just give the red buff to him/her. Blue buffs should be for your caster. If your caster is a manaless caster (eg.
Vladimir,
Kennen, etc., and your jungler doesn't need it too, you may want to take it)
For farming use your
Bladesurge or
Transcendent Blades IF you need to or else simply last hit with your auto attack. If needed, use your Hiten Style active to help you with farming. It will save much more mana than just simply
Bladesurgeing for every last hit.
Prioritize
Transcendent Blades for farming 6+ minions at once, for it will save you time and mana. However, if you believe that a teamfight may start soon, be sure to save this ultimate.
When a creep wave is at your turret and your turret is attacking them, 2 hits are required for the melee minions and 1 hit with an auto-attack+
Bladesurge, or an active
Hiten Style should get the minions. 1 hit from turret for caster minions. Sometimes an active
Hiten Style and a
Bladesurge after is required for the minion kill.
If you do have a
Trinity Force, activating
Hiten Style and
Bladesurge-ing after to a minion will garuntee a kill. That is only if you have the
Sheen passive on.
Learn to farm. I can't really teach you how to. No one can. Once you learn to farm well,
Irelia will become so scary.

Jungling
Though I personally don't like jungle
Irelia, I decided to include it anyways for those who actually like the whole idea. When jungling with
Irelia, always take
Smite and another summoner spell. You take
Smite to speed up your jungle route and also so you don't die to jungle camps.
While jungling, you will definitely want start with
Hiten Style as it will not only help you clear the jungle faster with that extra true damage power, but it will also heal you for each hit. Because of this, you may want to consider attack speed marks, seals, glyphs, or quintessences. Skill sequence later is quite simple with
Bladesurge to pick off last hits and to cover some distance. If you plan on ganking at an earlier level (which you should actually practice doing), you may want to take
Equilibrium Strike at level 1 or level 2.
For your item build, consider starting with a
Cloth Armor and 5
Health Potions, a
Regrowth Pendant and a
Health Potion, or
Boots of Speed and 3
Health Potions. If you started with a
Cloth Armor, directly rush a
Wriggle's Lantern. If you started with a
Regrowth Pendant, build a
Philosopher's Stone. If you started with Boots of Speed, you may choose to finish building a tier 2 boots or simply rush a
Wriggle's Lantern,
Wit's End, or a
Phage. Not that if you do start with
Boots of Speed and 3
Health Potions, you may need a good leash as
Irelia's
Hiten Style is much weaker now and you may not be able to sustain well enough without the extra armor or HP regen against the stronger jungle creeps.
As a jungler, you'll probably be in charge of stealing the baron nashor if the enemy team decides to attempt it. If for some reason you do not have
Flash with you,
Bladesurge may be the way to get it (this is if you have vision on the baron nashor or else you cannot target anything with
Bladesurge). Often if you just walk up to the enemy team while they're doing baron, they'll either just turn around and kill you, or quickly take baron and then kill you.
Bladesurge on the other hand provides a quick way to dash in and
Smite the baron nashor. A good tip is to click on the baron nashor to see how much HP is remaining, and with good judgement, dive in, and use
Smite at the right time. If possible, you can even communicate with your team to follow you into the whole "steal baron and ace the enemy team" idea.
Ranked Play Teamfights
Teamfights tend to happen all around the game. As mentioned previously, if you did any well in the beginning of the game, don't be afraid to initiate as long as your teammates help you after you initiate.
Your job is to target the squishies. If the enemy team has champions that have very little amount of HP bars, that is your target. If you cant kill them, injure them enough to keep them out of the fight. Burst them down ASAP. Good targets are like AD carries (eg.
Vayne,
Ashe,
Graves, etc.) or casters (eg.
Brand,
Ryze,
Annie, etc.). If you have a
Frozen Heart, you basically shut the enemy AD carry easily with the aura debuff on them reducing their damage output like crazy.
Your stun is a powerful weapon throughout teamfights. As long as you aren't dead and regardless of how much HP you have left, as long as you have your
Equilibrium Strike up, you remain as a huge threat. A 2 second stun is no joke and can easily turn the game around. Go for casters or the enemy AD carry as usual Sometimes it is better to concentrate on the fed enemies even if it is the tank. Remember that stuns will stop channeling spells, so spells like
Nunu's
Absolute Zero,
Katarina's
Death Lotus, and Warwick's
Infinite Duress will be canceled if you stun them. Use your stun wisely
