Irelia vs LeBlanc

Mark your targets with Flawless Duet (E) or Vanguard's Edge (R) before Bladesurge (Q): if the target is Unsteady or dies to it, its cooldown resets.

Before a trade, hit minions with Bladesurge (Q) to stack Ionian Fervor (passive): each stack gives attack speed, and at max stacks your autos hit harder.

Place the two blades of Flawless Duet (E) on either side of your target: only enemies caught between them are stunned.

Use Defiant Dance (W) to absorb a burst: you take less damage while charging, and the longer you hold it, the harder the release hits.

As soon as Ethereal Chains (E) tethers you, move away from her: if you stay chained for 1.5 seconds, you're rooted and take extra damage.

Trade while Distortion (W) is on cooldown: it's her dash both to get in and to get out, and it comes back in 15 to 10 seconds.

If you have a shield or a heal, save it for her combo: Sigil of Malice (Q) detonates as soon as another spell hits you, and all her damage lands at once.

If you have CC, aim at the starting point of her Distortion (W): within 4 seconds, she can return there by recasting the spell.

When she drops below 40% health, find the real LeBlanc before hitting: Mirror Image (passive) makes her invisible for 1 second and leaves a copy that deals no damage.
