Kha'Zix vs Taliyah

Jump on an isolated target with Leap (E), then Taste Their Fear (Q): with no ally nearby, Unseen Threat (passive) marks them and the spell hits much harder.

In teamfights, cast Void Assault (R) to vanish and reposition: the invisibility triggers Unseen Threat (passive), and your next auto damages and slows.

Detonate Void Spike (W) close to you in the jungle or in teamfights: you heal if you're inside the explosion area.

Pick your evolutions to fit the game: evolved Leap (E) resets on each takedown, evolved Taste Their Fear (Q) gains range and a lower cooldown on isolated targets.

When Unraveled Earth (E) is on the ground, don't cross it with a dash or get thrown through it by Seismic Shove (W): the stones explode under you and stun you.

If you can engage, go in after Seismic Shove (W): without it, she has nothing left to push you back, and no dash to escape.

If you have CC, save it for Taliyah while she surfs on Weaver's Wall (R): once immobilized, she stops surfing immediately.
