Playing as Kassadin

Tips to maximize your impact

  1. Trade with Q against mages

    Against a mage, take your trades with Null Sphere (Q): it gives you a magic damage shield for 1.5 seconds and interrupts channels.

  2. Restore mana with your W

    Restore mana with Nether Blade (W): your next auto restores part of your missing mana, more on a champion.

  3. Farm while you wait for Riftwalk

    Farm safely early on: your power comes from ranks in Riftwalk (R), whose cooldown drops from 5 to 2 seconds.

  4. Watch your mana when chaining R

    Chain Riftwalk (R) in teamfights while watching your mana: each quick recast adds damage, but doubles its mana cost.

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.
