How to play as Briar

Don't spend Blood Frenzy(W) into active Grass Q; wait it out or hit Certain Death(R) while Qiyana is visible, then use the mark's true sight to keep her from escaping the follow-up.

Elemental Wrath/Edge of Ixtal(Q) with the grass element makes Qiyana invisible and can break Briar's normal Blood Frenzy(W) pursuit; after Certain Death(R) marks Qiyana, its true sight keeps her revealed through the stealth.

Crimson Curse(P) and Snack Attack(W) provide healing in a sustained fight, while Qiyana's strength is front-loaded into a short burst; if Briar survives the first combo, Qiyana's stealth is her main way to disengage.

How to play as Qiyana

Use Grass Q to break Briar's ordinary W pursuit, but treat it as a short reset rather than a full counter; if Briar has marked you with R or the first combo fails to kill her, leave instead of taking the extended fight.
