Agaist easy matchup slowly push the wave and get lvl 2 priority. If you are playing with ignite, it's a really good time to get a kill. Tge wave will crush under enemy turret.if you do it, go back. If no, wait for a cannon wave. Pusj it abd ward jungle or river. Irelia is really good at 2v2 fights
Agaist hard matchup take e at level one. Let ebemy push tye wave, and freeze it before wave crushes into youtr turret. Agsist hard matchup farm to level six, ans dont try to fight.

In mid game, if you are on top, try to get the first turret. With your high push potential and a lot of bonus attack speed with your passive it isn't that hard as it could be. Often leave a lane to ward the jungle or river- enemy won't follow you, because he will lose all the cs under his turret.
Irelia mid gameplay is very diffrent, than top irelia. You should more help yoir laners abd jungler, than get the turret. Of course, if your team isn't losing the game it isn't bad idea, but in general helping team is more effective.

Push side lanes. If you have teleport up, u can go on a diffrent place on a map than your team, because you can always teleport to them. With tytanic hydra, ravenous hydra,or even a single tiamat, your push power is incredible.

Irelia doesn't have a lot of combos. Her playstyle and outplay potensial depends on a situation, how she can use her q,hoe many people will she hit with one spell-e.
With all of this, you should learn in game, what u need to do in deffresnt situations
Example combos are:
- R+e1 at the same time->q->auto attack(s)->e2-> auto attack(s)->q-> again aa-> and last q to finish off enemy
- q+e1 (at the same place as q)- very hard to see
- e1 on enemy, e2 on you
- w+e2- it works the best with a project skin. This skin has a lot og mkre animations than others, so it's easier to hide an e2 i her w. Of course, it works with ecery skin, but worse.

Q,w,e,r with flash. Always use skill before flash to make sure that you will do it as fast as it is possible.

Q-flash does damage a lot fastee than normal q
W flash is really good with finishibg off enemy who escaped
E flash isnt that good as q,w or r, but it is always faster than normal flash e
R flash cancels r animation.

- you can use smite, minion dematerializer or any ally to kill the minion, on which you are using q. You won't get a stack, but it gives you faster next q, to come closer to enemy
- attacking jungle camps and champions reset your time on passive. With this trick you can pass the river without losing any stacks! (While attacking rift scuttler, herald or baron)
- w,e and r gives you one stack, per champion which it hits. With this knowledge yoylu can get 5 stacks with only one spell. Very hard, but possible

1. This champ is very funny to play and gives a lot of satisfaction, when you make a really good outplay
2. In-game:
- she is quite tanky and has incredible damage at 5 stacks (when she is fed, without them too!)
- she can start teamfights with her ult when she wants
- with irelia you are better in every game, no like witn some champions without too many mechanics
- irelia snowballs really well. Sometimes one kill gives you free win

Disadventages:
- when she is behind, it is very, very hard to comeback to game.
- if you are new in league of legends, you need to learn how to play with camera unlocked and with quick casts
- this is so bad feeling when your q doesn't kill the minion and you need to wait this 10 seconds in early game to get this again

Most of people say, that playing ignite ob top is cringe. Meybe it is truth, but why shouldn't you go this is you feel better? My answer on a queshion in the name of the chapter is- take what you want. Or take both of them without flash ;). It is an option too.

With irelia, you often starts them. Try to hit the good ult (at least 3 enemys) and wait for team. If your team doesn't engage, use q to the ons of hit enemy champs.
If it is nesesarry, use w to absorb the incoming damage.
You e is albo important. It isn't a slow, like your ult, but it is a stun. Try to hit as many poeple as you can. It allows your team to go in, because enemy cant to anything and heal for you (with a lot of damage!).
With irelia you often play frontline and try to kill enemy tanks or off tanks, but you can also try to catch an adc or midlaner. With your dashes, you can go throw the enemy team and easy kill an adc with some easy, simpe auto attacks.

A lot of people always play irelia with biscuit delivery and time warp tonic. In my opinion it isn't bad choice. If you don't know which runes should you take in this or this matchup, take them.
Generaly, for easy matchup its better to take aggresive runes with domination. It gives you kill pleasure in the first minutez of the game
Taking resolve is the best agaist champs, who are fighting with you or poking you a lot. With resolve you will have mire hp in lane, but less damage, so it,s batter to stay and farm until you get blade of the ruined king.

Okay I think its everything what I wantes to tell you. Now u know teory, how to play her, The only thing what you need to do, is practising it in game. So what can I tell more, good luck you all!
