Irelia vs Gragas

Mark your targets with Flawless Duet (E) or Vanguard's Edge (R) before Bladesurge (Q): if the target is Unsteady or dies to it, its cooldown resets.

Before a trade, hit minions with Bladesurge (Q) to stack Ionian Fervor (passive): each stack gives attack speed, and at max stacks your autos hit harder.

Place the two blades of Flawless Duet (E) on either side of your target: only enemies caught between them are stunned.

Use Defiant Dance (W) to absorb a burst: you take less damage while charging, and the longer you hold it, the harder the release hits.

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.
