Irelia reduces the duration of disables on herself based on whether she is Outnumbered by nearby champions. If she's in an even fight, she'll reduce disables by a small amount, if she's outnumbered, she'll reduce disables by a larger amount.
Q - Bladesurge
Irelia dashes forward to strike her target. If it kills the target, Bladesurge's cooldown refreshes and refunds a portion of the Mana Cost.
W - Hiten Style
Irelia is skilled in the art of Hiten, passively giving her physical attacks Health restoration. Activating Hiten Style doubles her Health restoration and gives her basic attacks true damage.
E - Equilibrium Strike
Irelia's attack balances the scales, dealing damage and slowing the target. However, if the target has a higher Health % than Irelia, then the blow stuns the target instead of slowing.
R - Transcendent Blades
Irelia summons 4 spirit blades that she can fling to deal physical damage and siphon life from enemies they pass through.
