Everything MAY be Half-Done since I am not bothered

Try to look for an all in kill Lvl 2 If its POSSIBLE If not just continue to Farm.

COMBOS:
E > E > Q > AA > R (If needed) > AA
R > Q > AA > E > AA > E > Q > W > AA

E > W > W > Q > R > Q > AA

Irelia Stacks her Q, giving Atk spd. Maximum Stacks gives On Hit dmg.

Q: Dashes to a target dealing damage and healing herself. IF the enemy is marked or dies to your Q the Cooldown is replenished (EXTREMELY good for CS)

W: A charging strike which deals more damage the longer held. Phys dmg is reduced whilst charging

E: Two blades sent out which will create a straight line dependent on where they are placed, Enemies which are caught inside the line will be stunned, Marked, And damaged.

R: Fires out a projectile which then explodes outwards when hitting an enemy champion, ALL enemies hit will be marked and damaged. If enemies walk through the cage they will slowed and damaged.

Irelia thrives on mobility, using her passive and abilities to weave in and out of combat. Her Passive (Ionian Fervor) increases her attack speed based on stacks, allowing her to hit hard after some initial trading. Her Q (Bladesurge) enables her to dash to enemy minions or champions, resetting its cooldown on kills or assists.

Irelia's main source of CC Is mainly her E which provides a stun to ALL targets hit (Except Allies Obv)
Irelia's E is also go for initiated a trade or Running away (Which you should never have to do since you ALWAYS win lane)

May take awhile for you to learn her but once you do its cruise mode, just focus on improving your mechanics and timings, she has a high Skill ceiling. Like ALWAYS hitting your E.

irelia is vulnerable to CC and Hard engages unless your better (OFC)

Irelia can be caught out in Teamfights so make sure you have good positioning (If you want to be A posiitve player let your team take in all the CC and engage, then go in and kill them all (Optional of course))

In summary, Irelia is a versatile, mobile, and skill-based champion, good at dueling and team fights. preference to have quick reflexes, good timing, and good understanding of her abilities to unlock her full inner-alpha.

To summarize the summary just AUTO ATTACK WITH Q STACKED
