Playing as Katarina

Tips to maximize your impact

  1. 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).

  2. 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).

  3. 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.

  4. 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 Kai'Sa

How to counter and exploit weaknesses

  1. Stay near your minions

    Stay near your minions: Icathian Rain (Q) splits its missiles between nearby enemies, and on your own, you take them all.

  2. Harass her before she evolves

    If your attack range beats her 525 units, harass her early: Second Skin (passive) only evolves her spells as she buys items.

  3. Dodge her Void Seeker

    Dodge Void Seeker (W): it marks you with Plasma and reveals you, which lets Killer Instinct (R) dash onto you from very far away.
