Viego vs Gragas

Weave in an auto after each spell: thanks to Blade of the Ruined King (Q), your first attack on an enemy damaged by an ability strikes twice and heals you.

Charge Spectral Maw (W) when you have time: the longer the charge, the longer the first enemy hit stays stunned, but you're slowed in the meantime.

Cast Harrowed Path (E) on a wall near your target: inside the Mist, you're camouflaged and gain move speed and attack speed.

After a kill, hit the wraith to trigger Sovereign's Domination (passive): you restore health and take their basic spells and items, but not their ult.

Cast Heartbreaker (R) to finish: you leave the possessed body and strike the champion with the lowest health percentage, with damage based on their missing health.

Stay behind your minions: Body Slam (E) stops on the first enemy it meets, minions included.

Get out of the Barrel Roll (Q) area right away: the longer the barrel sits on the ground, the more its explosion hurts and slows.

Step up when Body Slam (E) hits nobody: its cooldown isn't reduced and stays at 14 to 12 seconds.

Spread out from your allies: Explosive Cask (R) knocks every enemy away from the impact, which can split you up or send you toward his team.
