How to play Kassadin in Patch 26.20, built from ranked games: power spikes, the lane plan, how leads convert, and the habits that separate Kassadin wins from losses.

Kassadin Power Spikes (Patch 26.20)

Bot

When Kassadin Bot gets stronger, in the order it happens in a typical ranked game: ability unlocks from the most common skill order, item spikes at the median minute players finish them, and the game length Kassadin wins most.

Lv 3
All three basic abilities at level 3
Kassadin's full combo is online — the first point where trading all-in is realistic.
Lv 6
Ultimate rank 1 at level 6
The biggest early spike: look for a kill or a roam as soon as Kassadin hits it.
Lv 11
Ultimate rank 2 at level 11
Lower ultimate cooldown means more fights Kassadin can start or win.
Lv 16
Ultimate rank 3 at level 16
Lower ultimate cooldown means more fights Kassadin can start or win.

Item timings are medians: half of players finish later. Fall behind in farm and every item spike moves back with it.

Kassadin Mid and Late Game

What Kassadin does better or worse than other champions after laning, from this patch's ranked games — percentiles where 100 is the highest of every champion.

Play to these strengths

Kassadin is a main damage source (83/100): stay alive and in range for the whole fight rather than diving first.
Kassadin wins 12.7 points more in long games than short ones: avoid coin-flip fights early and let the game go long.

Mistakes to avoid

Vision is a weak spot (4/100): buy Control Wards and sweep before you face-check.

Playing Kassadin

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.

Playing Against Kassadin

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.
