Playing as Kassadin

Tips to maximize your impact

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

How to counter and exploit weaknesses

Trade before he hits 6
Take as many trades as you can before he hits level 6: without Riftwalk (R), he has no way to move quickly, to engage or to escape.
Lean on physical damage
If you deal physical damage, lean on it in trades: Void Stone (passive) and Null Sphere (Q) only reduce magic damage.
Drag it out when he chains R
When he recasts Riftwalk (R) back to back, back off and drag the teamfight out: each quick recast doubles its mana cost, and once he's out of mana he can't blink anymore.
End the game early
Look to end the game early: at max rank, Riftwalk (R) only has a 2-second cooldown, and he blinks almost nonstop.

Void Stone (P)

Kassadin takes reduced magic damage and ignores unit collision.
