Qiyana vs Lillia

Pick your Terrashape (W) element for the job: river for an Ice root, terrain for Rock's bonus damage on low-health targets, brush for Wild's invisibility.

Cast Terrashape (W) right after Elemental Wrath (Q): the dash resets its cooldown, so you can recast it in the same combo.

Cast Supreme Display of Talent (R) toward a wall near the enemies: the explosion runs along the whole edge of the obstacle, and any river or brush it crosses explodes too.

Roam with Wild, the brush element: Elemental Wrath (Q) then leaves a trail that makes you invisible and speeds you up.

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.
