Talon vs Xin Zhao

Apply three Blade's End (passive) stacks by hitting with your spells, then strike with an auto: the target starts bleeding and takes heavy damage over time.

Cast Noxian Diplomacy (Q) in melee range when you can: instead of the leap, it lands a critical strike. If it kills, it heals you and comes back faster.

During Shadow Assault (R), break invisibility with an auto or Noxian Diplomacy (Q): the blades then converge on your target instead of coming back to you.

Push your wave, then roam by vaulting walls with Assassin's Path (E): the spell comes back fast, but you can only cross the same wall again after a long delay.

Get out of the line of the Wind Becomes Lightning (W) thrust: it slows you and marks you as Challenged, which extends the range of Audacious Charge (E) on you.

If you have CC, use it during Three Talon Strike (Q): without his three autos, there's no knock-up, and his other cooldowns don't go down.

After Audacious Charge (E), keep your distance: it's his only dash to get back on you, and without it he has to walk up to you.

After Crescent Guard (R), don't hit him from range: for a moment, he ignores damage from outside the swept zone. Back off, or hit him from inside it.

If you survive his first minutes, play for time: Xin Zhao is strongest early on, through his ganks and skirmishes.
