Playing as Karthus
Tips to maximize your impact
- Aim for isolated champions
Aim Lay Waste (Q) at a champion away from their minions: if the blast hits only one enemy, it deals much more damage.
- Wall before your combo
Place Wall of Pain (W) in their path before your combo: anyone who crosses it is slowed and loses magic resist.
- Keep playing after you die
After you die, keep casting your spells: Death Defied (passive) keeps you in spirit form for a while, and you can still cast Lay Waste (Q) and Requiem (R).
- Requiem for the finish
Save Requiem (R) to finish off wounded enemies, often right after a teamfight: it hits every enemy champion wherever they are, after a 3-second channel.
Playing against Hwei
How to counter and exploit weaknesses
- Trade after his damage spell
Trade after he uses a damage spell: Devastating Fire (QQ), Severing Bolt (QW) and Molten Fissure (QE) share a 10 to 6 second cooldown.
- Don't stand still or alone
Don't stand still or alone: Severing Bolt (QW) strikes after a delay and deals more damage to isolated or immobilized enemies.
- Jump on him if you can
If you can engage, jump on him right after one of his CC spells: Hwei has no dash or leap, and Subject: Torment (E) has a 12 to 10 second cooldown.
- Move away from the ally hit by his R
If an ally is hit by Spiraling Despair (R), move away from them: the vision expands around its target, slows and damages nearby enemies, then explodes.
