Hwei vs Locke

Poke with Devastating Fire (QQ) in lane: the fireball explodes on the first enemy hit and adds damage based on their max health.

Hit the same champion with two damaging spells: Signature of the Visionary (passive) then leaves a signature beneath them that explodes shortly after.

Pick the subject that fits the moment: Devastating Fire (QQ) for damage, Pool of Reflection (WW) to protect your allies, Crushing Maw (EE) to pull a group together.

Block a chokepoint with Molten Fissure (QE): the line of eruptions leaves pools of lava that slow and damage enemies.

Cast Spiraling Despair (R) on a champion surrounded by allies: the vision expands around them, slowing harder and damaging nearby enemies before it explodes.

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.
