Volibear vs Irelia

Cast Thundering Smash (Q) to charge at your target: your speed doubles when heading toward a champion, and your next auto stuns them.

Hit the same target twice with Frenzied Maul (W): the second hit, on the marked target, hits harder and heals you based on your missing health.

Cast Sky Splitter (E) where you're fighting and stay in the zone: when the lightning strikes, you gain a shield, and enemies hit are slowed.

To dive under a tower, cast Stormbringer (R) near it: on landing, you disable it for a few seconds, and you gain bonus health.

Don't stand near your low-health minions: Bladesurge (Q) resets when it kills, so she chains dashes from minion to minion until she reaches you.

As soon as the first blade of Flawless Duet (E) lands, change direction: the stun only hits enemies caught between the two blades.

Take your trades when Ionian Fervor (passive) isn't stacked: she builds stacks with her abilities, and at max stacks her autos deal more damage.

Save your burst for after Defiant Dance (W): while charging, she takes much less damage, but she can't do anything else.

Dodge Vanguard's Edge (R): its blades make you Unsteady, which resets Bladesurge (Q) on you, and the cage they form damages and slows anyone who crosses it.
