Playing as Cassiopeia

Tips to maximize your impact

  1. Poison, then bite

    Land Noxious Blast (Q), then chain Twin Fang (E) while the poison lasts: the poisoned target takes extra damage, and you heal.

  2. Kite with your speed

    Hit a champion with Noxious Blast (Q) to kite: the spell gives you move speed, and Serpentine Grace (passive) makes every speed bonus more effective.

  3. Ground those who dive you

    Place Miasma (W) on those trying to jump on you: inside the clouds, enemies are slowed and can't use movement abilities.

  4. Turn to face your pursuers

    Cast Petrifying Gaze (R) toward those chasing you, after a Flash if needed: those facing you are stunned, the others only slowed.

Playing against Vel'Koz

How to counter and exploit weaknesses

  1. Watch both branches of his plasma

    Get out of the line of Plasma Fission (Q) and watch its sides too: the bolt splits into two branches at 90 degrees when it hits a target or he recasts it.

  2. Back off before the third stack

    Back off after taking two of his spells: at the third Organic Deconstruction (passive) stack, you take a burst of true damage.

  3. Engage after Tectonic Disruption

    If you can engage, go in after Tectonic Disruption (E): it's his only spell to push back someone charging him, and he has no dash to escape.

  4. Interrupt his ray

    If you have a stun, a silence or a knock-up, save it for Life Form Disintegration Ray (R): any of them interrupts the ray.
