Playing as Smolder

Tips to maximize your impact

  1. Last-hit minions with your fireball

    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.

  2. Poke with your sneeze

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

  3. Aim for the final tier

    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.

  4. Take flight to escape

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

  5. Call your mom from far away

    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.

Playing against Karthus

How to counter and exploit weaknesses

  1. Stay near your minions

    Stay near your minions or your allies: Lay Waste (Q) deals much more damage when the blast hits only one enemy.

  2. Jump on him if you can

    If you can engage, jump on him: Karthus has no dash or leap to escape.

  3. Don't stay low once he hits 6

    Once he hits level 6, back instead of staying at low health: Requiem (R) hits every enemy champion wherever they are, 3 seconds after he starts channeling.

  4. Save your protection for Requiem

    If you have a shield, a heal or invulnerability, save it for Requiem (R): it hits every enemy champion 3 seconds after he starts channeling.

  5. Move away after he dies

    Once Karthus is dead, move away: Death Defied (passive) keeps him in spirit form for a while, and he can still cast his spells.
