Briar vs Lillia

Cast Blood Frenzy (W) only when you want to end the fight: you charge the nearest enemy, champions first, without choosing your target.

Save Snack Attack (W) for when you're low: your next auto deals damage based on the target's missing health and heals you for part of it.

Fully charge Chilling Scream (E) near a wall: the scream then knocks enemies back, and those who hit the wall are stunned.

Cast Certain Death (R) across the map to engage or catch a target: you fly to the first champion hit and chase them until they die.

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.
