Gragas vs Taliyah

Let Barrel Roll (Q) charge before detonating it: damage and slow grow the longer it sits on the ground, and if you don't recast it, it explodes on its own.

Drink Drunken Rage (W) before engaging: drinking takes 1 second, then you take less damage and your next auto hits every nearby enemy.

Engage with Body Slam (E) through a path without minions: you stop on the first enemy you meet, and hitting reduces its cooldown.

After Body Slam (E), cast Explosive Cask (R) behind your target: the blast knocks enemies away from the impact, sending them toward your team.

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.
