Lillia vs Xin Zhao

Hit with the edge of Blooming Blows (Q), not the center: only the outer edge adds true damage.

Hit enemies with your spells and keep your distance: Blooming Blows (Q) gives you a stack of move speed on each hit, enough to kite and dodge.

Start the fight from range with Swirlseed (E): it damages, slows and reveals, and if it hits nothing, it rolls on to the first enemy or wall.

Before Lilting Lullaby (R), hit as many enemies as you can: Dream-Laden Bough (passive) marks every target of your spells, and only marked ones fall asleep.

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.
