Playing as Smolder
Tips to maximize your impact
- 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.
- 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.
- 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.
- Take flight to escape
Escape or reposition with Flap, Flap, Flap (E): you fly over obstacles, bombarding the enemy with the lowest health.
- 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
- 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.
- Jump on him if you can
If you can engage, jump on him: Karthus has no dash or leap to escape.
- 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.
- 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.
- 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.
