Shaco vs Locke

Gank with Deceive (Q) and come in behind your target: Backstab (passive) empowers hits from behind, and your first invisible auto becomes a critical strike.

Save Two-Shiv Poison (E) to finish: the shiv deals much more damage to a target below 30% health.

Cast Hallucinate (R) to bait their spells: you briefly disappear and reappear with a clone, which explodes on death into three boxes that fear.

Place Jack In The Box (W) on their escape routes or at a camp entrance: invisible after a delay, it fears champions who come near, then shoots them.

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.
