Anivia vs Locke

Recast Flash Frost (Q) when the orb reaches your target: it explodes at once and stuns, without waiting for the end of its range.

Cast Frostbite (E) right after Flash Frost (Q), or inside a fully formed Glacial Storm (R): against a chilled target, its damage doubles.

Place Crystallize (W) behind a fleeing enemy: the ice wall blocks the path before it melts.

Play more aggressively when Rebirth (passive) is available: instead of dying, you turn into an egg, and if it isn't destroyed, you come back at full health.

Back instead of staying in lane at low health: Silver Stake (passive) adds damage to his autos that grows with your missing health.

Trade after Ashen Pursuit (E): it's his only instant movement, and its 10-second cooldown only resets if he gets a takedown.

During Soul Ignition (W), only hit him if you can kill him: at the end, he heals back part of the last damage taken, yours included.

Marked by Purgatory (R), stay above its threshold: if you have a heal or a shield, use it, because he seals marked enemies who drop below it.

If the Purgatory (R) artifact lands, hold the area where it fell: by picking it up, Locke raises his execute threshold for each sealed champion, for the rest of the game.
