Camille vs Irelia

Wait a moment before the second Precision Protocol (Q) attack: after a short delay, it hits harder and part of its damage becomes true damage.

Hit your opponent with the outer half of Tactical Sweep (W): they are slowed, take extra damage, and you heal for part of it.

Fire Hookshot (E) at a wall near your target, then leap: you stun champions where you land, and the leap goes twice as far toward a champion.

Cast The Hextech Ultimatum (R) on their carry: they can't leave the zone, other nearby enemies are knocked away, and you interrupt their channels.

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.
