Passive: Ionian Fervor
Each nearby enemy champion (to a maximum of three) reduces the effectiveness of Crowd Control on Irelia.1 Champion: 10%2 Champions: 25%3 Champions: 40%
Irelias Passive is one of the few superman passives in LoL. Tenacity reduction(Tenacity= lower effect of CC) ist realy good! And this passives allows u for ex. to walk out of a Galio Ult before its explodes it also helpes emensly to jump at the enemy Carry without getting stoped through CC.
Irelia dashes forward to strike her target for 20/50/80/110/140 (+1 per Attack Damage). If it kills the target, Bladesurge's cooldown refreshes and refunds 35 Mana.
Cooldown 14 / 12 / 10 / 8 / 6 seconds
Cost 60/65/70/75/80 mana
Irelias Q is really strong either. Early on its good for lasthitting and escaping ganks. And later in the game, when u put some points in it u are able to one shot Casterminions with it. All in all ur main utility spell. Max this second unless u nedd the CC from e.
W: Hiten Style
Irelia is skilled in the art of Hiten, passively giving her physical attacks 5/7/9/11/13 health restoration. Activating Hiten Style adds 15 / 30 / 45 / 60 / 75 true damage to her physical attacks for 6 seconds and gives her physical attacks 10/14/18/22/26 health restoration.
Cooldown 15 seconds
Cost 40 mana
The W spell is one of the reason why Irelia was/is concidered OP. It gives u so much damage and sustain in lane that u have to max this for a good laning phase. It has been nerfed pretty hard tho but its still amazing.
E: Equilibrium Strike
Irelia's attack balances the scales, dealing 80 / 130 / 180 / 230 / 280 (+50% of ability power) damage and slowing the target by 60% for 1 / 1.25 / 1.5 / 1.75 / 2 seconds. However, if the target has a higher Health % than Irelia, then the blow stuns the target instead.
Cooldown 8 seconds
Cost 50 / 55 / 60 / 65 / 70 mana
Her E is a bit tricky if u got more health then ur target u will slow it. If ur target has more health it will be stuned. Use it wisly in trades or for some turnarrounds under ur tower ;)
R: Transcendent Blades
Irelia summons 4 spirit blades that she can fling to deal 80/120/160 (+60 of attack damage) (+50% of ability power) physical damage to enemies they pass through. She heals for 25% of that damage against champions and 10% against minions.
Cooldown 70/60/50 seconds
Cost 100 mana
Her Ult is also realy nice either for wave clearing or fighting it will sustain u and do lots of damage.
