Gragas vs Wukong

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.

Trade after Warrior Trickster (W): it's his best escape, and it has a 22 to 18 second cooldown.

When Warrior Trickster (W) turns him invisible, ignore the figure standing still: that's the clone, and the real Wukong just dashed off to the side.

When he has Cyclone (R), spread out from your allies: he spins in the middle of your team and knocks every nearby enemy into the air, twice.

If you have a way to escape, wait for his second Cyclone (R) to end: the spell can be recast once, and each spin knocks nearby enemies into the air again.
