The Blade Dancer
Hitting enemies with spells grant Irelia stacks of Ionian Fervor for a few seconds. Hitting multiple champions with an ability grants multiple stacks, and basic attacking extends their duration. Each stack adds bonus magic damage to her basic attacks. At max stacks, this bonus damage is increased against shields, and Irelia also gains attack speed.
Irelia dashes to a target, dealing physical damage (increased if it’s a minion or monster), applying on-hit effects, and healing for a small amount.
If the target was marked or dies to Bladesurge, its cooldown is refreshed.
First Cast: Irelia begins charging her blades, losing the ability to move or attack but gaining significant damage reduction for a brief period. This channel can’t be interrupted.
Second Cast: Irelia lashes out with her blades, dealing physical damage in a line. The damage increases as Irelia charges.
Irelia sends a blade to a location, and can recast Flawless Duet to send a second blade to another location. The blades will then fly towards one another, dealing magic damage and stunning enemies caught in the crossfire. Flawless Duetalso marks champions and large monsters for a few seconds.
Irelia unleashes the full force of her blades in a line. If Vanguard's Edge hits an enemy champion, the blades will radiate outward, dealing damage and marking enemy champions and large monsters, and forming a barrier that lasts for a few seconds. This blade wall deals magic damage and significantly slows enemy champions that pass through it. It also disarms them for a few seconds, making them unable to basic attack.
''The sword flourishes, as though painting with blood.''
The Ionians have developed some of the most breathtaking and deadly martial arts in all of Runeterra - just one manifestation of their pursuit of enlightenment. The most remarkable blade style to emerge, however, was the unusual byproduct of foreign intervention.
Master Lito was a swordsman whose teachings were sought by ruling classes from nearly every city-state. His art was a highly-guarded secret, but it was said that swords would breathe in his grasp. He withered unexpectedly from a mysterious disease which baffled the brightest of Runeterran physicians. When he died, he left behind Zelos and Irelia, his son and daughter, and a truly unique weapon. Zelos became a sergeant in the Ionian military and left to seek assistance from Demacia immediately prior to Noxus' invasion of Ionia. Irelia, charged with the protection of their home until Zelos returned, was alone when the Noxian forces struck.
The Ionians fought admirably, but soon Ionian blood stained the land beneath the prints of foreign boots. At the Great Stand of the Placidium, Ionians prepared for surrender, but were inspired to maintain their resistance when the young Irelia lifted her father's enormous blade and pledged to hold until her brother returned. In the chaos of the ensuing fight, Irelia was cursed with dark Noxian Necromancy.
As her life ebbed, Soraka, the Starchild, made a final attempt to anchor her fading soul. Unwilling to relinquish her home, Irelia rose at the brink of death, and her father's weapon lifted into the air alongside her. Irelia rushed back to the fore, unfazed by the blade's sudden animation. The weapon danced around her effortlessly, cutting down Noxians as they gaped in horror. The decimated invaders were forced to retreat from the Placidium, and Irelia was appointed Ionia's Captain of the Guard for her brave defense of her homeland.
