When Is Kassadin Strongest?
The strong window is the later mid-game, once the build is mostly online, and games at this rank average around 27 minutes. Kassadin wins by surviving early and taking over late, so use the power window once his items are online to blink onto isolated carries, delete them, and slip away before the enemy can collapse.
Kassadin Item Build
Kassadin is a scaling assassin who suffers early, then becomes an unkillable blink threat once his core items land. The build pours into ability power, mana, and haste so his void magic bursts squishies and he can chain his teleports to dart in and out untouched.
Best Kassadin Runes
First Strike suits a champion who wants the mid and late game. It rewards him for landing the opening hit of a fight, which pairs with the burst his combo delivers once he can Riftwalk in. Keep the rest focused on mana and sustain so he survives the lane phase. Nothing fancy, just reach the point where his kit does the work.

Kassadin Skill Order
Force Pulse hoovers up levels 3, 4, 5, 7 and 9; Null Sphere, meanwhile, holds the single point it took at level 1 until level 14, so the shield and the channel interrupt stay at rank one for most of the game.
Kassadin Abilities
Force Pulse only fires once Kassadin has soaked up enough nearby spellcasts to charge it, so his cone slow is a reward for good positioning rather than a button on demand. Nether Blade is the quiet engine underneath, its active attack refunding Mana to fund the teleports everyone remembers him for.
Kassadin Base Stats
Kassadin Matchups
Kassadin dreads aggressive early lanes and poke mages who bully him before level six, since his magic resist passive does little against physical harass. He flips the script on immobile, ability-power casters late, blinking onto them and deleting them before they can respond.
