Quinn vs Irelia

Cast Vault (E) on the melee champion charging you: you leap back after the hit, and your target is slowed and marked by Harrier (passive).

Auto every target marked by Harrier (passive): your first auto on them deals bonus damage, and Heightened Senses (W) then gives you speed.

Against a melee champion, trade from range: Blinding Assault (Q) marks them with Harrier and reduces their vision before your empowered auto.

Roam with Behind Enemy Lines (R): after a 2-second channel, you gain a lot of speed, and an auto or a spell ends the flight with an area attack.

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.
