Lore
Cutting a burning swath through the darkest places of the world, Kassadin knows his days are numbered. A widely traveled Shuriman guide and adventurer, he had chosen to raise a family among the peaceful southern tribes—until the day his village was consumed by the Void. He vowed vengeance, combining a number of arcane artifacts and forbidden technologies for the struggle ahead. Finally, Kassadin set out for the wastelands of Icathia, ready to face any monstrous Void-construct in his search for their self-proclaimed prophet, Malzahar.
Ally Tips

Kassadin has multiple item paths; he can go caster via Mana and Ability Power or anti-caster with Cooldown Reduction and Magic Resist.

Kassadin's ultimate has many uses and is on a shorter cooldown than most, use it often.

Try to get the Ancient Golem buff to counteract Riftwalk's increasing Mana cost.

Enemy Tips

Kassadin deals mostly magic damage. If he's doing well consider buying magic resist items like Mercury's Treads and Banshee's Veil.

Each time Kassadin consecutively uses Riftwalk, he pays more and more mana. Keep this in mind as you chase him.

It takes 6 spell casts for Kassadin's slow, Force Pulse, to become castable. If he levels up that ability, judiciously use your own skills while laning against him.
