Zed vs Lillia

To kill, cast Death Mark (R), then Living Shadow (W), Shadow Slash (E) and Razor Shuriken (Q): with two shadows, you throw three shurikens.

Cast Death Mark (R) just as the enemy casts their decisive spell: during the dash, you're untargetable.

After Death Mark (R), save the recast to get out: you swap places with the shadow left at your starting point, far from the fight.

Save enough energy for a full combo rather than casting your spells for nothing: Living Shadow (W) refunds energy when you and your shadow hit the same target.

In teamfights, go around the sides and save Death Mark (R) for an isolated target: going in from the front exposes you to the whole team's CC.

Against Blooming Blows (Q), stick to her or back out of range: only the outer edge of the zone adds true damage.

Get out of the center of Watch Out! Eep! (W): the zone deals much more damage there than at the edge.

Dodge her spells, even Swirlseed (E), which rolls to the first enemy: each one marks you for Lilting Lullaby (R), which puts every marked enemy to sleep.

If you have CC, use it on her: with no dash, she relies on the move speed Blooming Blows (Q) gives her for each spell that hits.
