LeBlanc vs Locke

After Sigil of Malice (Q), hit the target with another ability: the sigil only detonates on a spell, not on an auto.

Take your trades with Distortion (W): within 4 seconds, recast it to return to where you started.

After Ethereal Chains (E), keep the target chained for 1.5 seconds: they're then rooted and take extra damage, giving you time to land your burst.

In the mid game, look for isolated targets rather than head-on teamfights: your burst focuses one target, and Distortion (W) then takes you back out.

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.
