Playing as Kai'Sa

Tips to maximize your impact

  1. Use Q on an isolated target

    Cast Icathian Rain (Q) on an isolated target: the missiles split between nearby enemies, so a lone target takes them all.

  2. Attack after your ally's CC

    Attack right after your support lands CC: with Second Skin (passive), your allies' immobilizing effects also stack Plasma.

  3. Mark your target before your R

    Before Killer Instinct (R), stack Plasma on your target, from range with Void Seeker (W): the dash needs a marked target and gives you a shield.

  4. Play around your evolves

    Make use of each spell that Second Skin (passive) evolves: Supercharge (E) makes you invisible to get in, and Icathian Rain (Q) fires more missiles at a lone target.

Playing against Heimerdinger

How to counter and exploit weaknesses

  1. Destroy his turrets first

    Take down his turrets before you trade, with your minions' help: each H-28 G Evolution Turret (Q) builds up charge over time, then fires a stronger shot.

  2. Dodge the center of his grenade

    Get out of the center of CH-2 Electron Storm Grenade (E): that's where it stuns, and if it hits a champion, it fully charges his nearby turrets.

  3. All-in after his grenade

    Start your all-in or gank after CH-2 Electron Storm Grenade (E): it's his only stun, it has an 11-second cooldown, and he has no dash.

  4. Pull him away from his turrets

    Take your trades away from his turrets: they deactivate when he moves too far from them, and Hextech Affinity (passive) speeds him up near them.

  5. Back off from his giant turret

    Stay out of his giant turret's range for its 8 seconds: placed with UPGRADE!!! (R), it slows, deals area damage and is immune to CC.
