Pantheon vs Irelia

Start your trades with Shield Vault (W): you leap onto your target and stun them, so Comet Spear (Q) can't miss.

Tap Comet Spear (Q) for a short thrust that refunds part of the cooldown, or hold it to throw your spear farther.

Raise Aegis Assault (E) against enemy burst: you ignore damage from that direction, except from towers.

Roam with Grand Starfall (R): you leap from long range onto the chosen area, and the spell instantly readies Mortal Will (passive).

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.
