Playing as Katarina
Tips to maximize your impact
- Pick up your daggers
Pick up your daggers in trades and teamfights: Voracity (passive) then hits every nearby enemy, and each dagger picked up lowers the cooldown of Shunpo (E).
- Shunpo to your Q dagger
After Bouncing Blade (Q), blink to its dagger with Shunpo (E): it lands behind your target, and picking it up triggers Voracity (passive).
- Hit everyone before the kills
In teamfights, hit as many champions as you can before they go down: when one of them dies, Voracity (passive) sharply lowers all your cooldowns.
- Death Lotus after their CC
Cast Death Lotus (R) once the enemy CC is used: it's a channel, and a single CC is enough to cancel it.
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.
