Aurora vs Locke

Poke with Twofold Hex (Q), then recast it once the target has lost health: the hex passes back through them and deals more damage the more health they're missing.

Cast Across the Veil (W) to dodge a skillshot or break a chase: you leap and turn invisible briefly, and a takedown resets its cooldown.

Cast Between Worlds (R) in the middle of grouped enemies: those trying to enter or leave the area are slowed, which keeps them under your team's spells.

Inside Between Worlds (R), teleport from one edge to the other to dodge skillshots and reposition, as long as the area lasts.

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.
