Akali vs Irelia

After each spell that hits, step out of the Assassin's Mark (passive) ring: your next auto gains range and damage.

Mark your target with Shuriken Flip (E) before leaping with Perfect Execution (R): recasting Shuriken Flip takes you back to them, even after your leap.

Cast Twilight Shroud (W) to dive under the enemy tower: inside the smoke you are invisible and untargetable, but an auto or a spell reveals you briefly.

Save the second dash of Perfect Execution (R) to finish: its damage grows with the target's missing health.

Don't stand near your low-health minions: Bladesurge (Q) resets when it kills, so she chains dashes from minion to minion until she reaches you.

As soon as the first blade of Flawless Duet (E) lands, change direction: the stun only hits enemies caught between the two blades.

Take your trades when Ionian Fervor (passive) isn't stacked: she builds stacks with her abilities, and at max stacks her autos deal more damage.

Save your burst for after Defiant Dance (W): while charging, she takes much less damage, but she can't do anything else.

Dodge Vanguard's Edge (R): its blades make you Unsteady, which resets Bladesurge (Q) on you, and the cage they form damages and slows anyone who crosses it.
