Sett vs Kassadin

Updated Jun 4, 2026

Overview

Sett should use his early lane pressure and strong melee trades to deny Kassadin a passive scaling lane.
Focus on forcing close-range fights where Sett's grit and (W) shield can outlast Kassadin's poke and low early mobility.
This matchup is a control versus scaling duel where Sett must dominate early to prevent Kassadin from reaching his power spikes.

Trading pattern

Start trades with autos and (E) to lock Kassadin in melee range, then spend grit with centered (W) for maximum damage and shield.
Punish Kassadin's low pre-6 mobility by forcing trades when his (R) is on cooldown or mana is low.
Avoid wasting (W) by baiting Kassadin to commit before hitting the center; sidestepping his (Q) shield with grit trades is key.

Danger windows

Kassadin is most dangerous post-6 when he can use (R) for burst and mobility; respect his ability to reposition and disengage.
Avoid extended trades when Kassadin has full mana and (R) stacks available.
Be cautious after missing (E) or spending (W) as Sett becomes vulnerable to Kassadin's short trades and poke.

Early game

Aggressively pressure Kassadin before level 6 while he lacks mobility and escape tools.
Use (E) to pull Kassadin when he stands near minions to set up stun and grit trades.
Avoid extended ranged poke and look for level 3-5 windows to force short brawls with grit buildup.

Power spikes

Level 6: Use (R) to reposition Kassadin into your team or under tower for all-in engages; punish Kassadin after he uses (R).
First bruiser item: Increase durability and pressure to force Kassadin into short trades or losing farm.
Respect Kassadin's level 6 (R) mobility and burst; hold key cooldowns to counter his engage or escape attempts.

Win conditions

Dominate early trades using (E) stuns and grit-backed (W) to deny Kassadin farm and scaling.
Use level 6 (R) to force fights or roams, disrupting Kassadin's positioning and limiting his side-lane pressure.
Maintain lane control and pressure to prevent Kassadin from safely farming and reaching his late-game power spikes.
