Why this duo works

Gragas can set up Yasuo with a Body Slam(E) knockup during ganks and a multi-target Explosive Cask(R) engage in fights. Yasuo players recommend Gragas as a jungle partner for the extra Last Breath(R) openings, while Gragas players warn that Yasuo must follow the cask quickly before its knockback spreads enemies apart.

Measured in High Elo: this duo wins 1.5pp more often than expected over 1,349 games.

Playing the duo

Body Slam(E) and Explosive Cask(R) can displace enemies into airborne states that Yasuo can target with Last Breath(R); the cask can affect several enemies at once.

How to play as Gragas

On a mid gank, aim Explosive Cask(R) so its knockback puts enemies within Yasuo's follow-up, or use Body Slam(E) to create the airborne trigger; cue Yasuo to R quickly if your cask scatters several targets.

How to play as Yasuo

When Gragas ganks mid, follow Body Slam(E) or the knockback from Explosive Cask(R) with Last Breath(R) before the displaced enemies spread apart.
