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 Zyra
How to counter and exploit weaknesses
- Dodge her roots
Get out of the line of Grasping Roots (E): the roots pass through minions and root every enemy hit, then her plants hit the trapped target.
- Step on her seeds
Step on her seeds to destroy them before she grows them: Rampant Growth (W) seeds reveal you for a moment, but leave her no plant.
- Kill her plants
Take down the plants born from Garden of Thorns (passive), or back off until they die: they take fixed damage, like a ward, and don't live long.
- Get out of her thorns
Get out of the Stranglethorns (R) zone as soon as it appears: the vines knock you into the air 2 seconds later, and her plants are empowered inside.
- Engage when her plants are far
If you can engage, go for Zyra when her plants are far from her: the Thorn Spitter from Deadly Spines (Q) only fires at 575 range.
