Smolder vs Locke

Last-hit minions with Super Scorcher Breath (Q): each kill with the spell gives you a Dragon Practice (passive) stack, which empowers your basic spells.

Poke with Achooo! (W): the sneeze slows, explodes on champions hit, and each champion hit gives you a Dragon Practice stack.

Build enough stacks for the final tier of Super Scorcher Breath (Q): it burns its target, and kills a champion who drops below a health threshold.

Escape or reposition with Flap, Flap, Flap (E): you fly over obstacles, bombarding the enemy with the lowest health.

Cast MMOOOMMMM! (R) to finish or slow from far away: the center of the breath hits harder and slows, and if it hits you, your mom heals you.

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.
