Swain vs Locke

Cast Nevermove (E) past your target: it only roots on the way back, as it returns to you. Then recast it to pull rooted champions to you.

Poke with Death's Hand (Q) even behind minions: its bolts pierce enemies, and its cooldown drops from 7 to 3 seconds.

Hit champions with Vision of Empire (W) and pull them with Nevermove (E): each Ravenous Flock (passive) Soul Fragment heals you and raises your max health.

During Demonic Ascension (R), stay close to enemy champions: the drain extends your form, and a takedown refills your Demonic Energy.

Cast Vision of Empire (W) on a fight breaking out elsewhere: its range is 5500 to 7500, and a busy or rooted enemy struggles to dodge the hit 1.5 seconds later.

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.
