Malphite vs Locke

Save Unstoppable Force (R) for when the enemy carries are grouped: nothing stops your charge, and the impact knocks every enemy in the area into the air.

Cast Seismic Shard (Q) before engaging or to escape: it slows the target and gives you the speed it steals.

Take your trades while Granite Shield (passive) is up: it absorbs 10% of your max health, and Thunderclap (W) then triples your bonus armor.

Against a champion who lives on autos, start your trades with Ground Slam (E): it lowers their attack speed, and its damage scales with your armor.

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.
