Naafiri vs Locke

Recast Darkin Daggers (Q) on a target that's already bleeding: the second dagger deals the rest of the bleed plus damage based on their missing health, and heals you.

When your pack has taken hits, cast Eviscerate (E): your packmates come back to you at full health.

Cast The Call of the Pack (W) just before you engage: you're briefly untargetable, your pack grows, and you gain AD and move speed.

Push your wave, then roam toward an isolated champion: with Hounds' Pursuit (R), you and your pack dash onto them, and a takedown lets you recast it.

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.
