Sylas vs Kassadin

Updated May 31, 2026

Overview

Sylas is a high-agency melee skirmisher who must pressure Kassadin early to deny safe scaling.
Use E to engage and W for sustain to challenge Kassadin's weak pre-6 lane presence without giving him easy farm.

Trading pattern

Use E to initiate trades, then follow up with W for healing and Q to slow Kassadin, disengaging if cooldowns expire.
Punish Kassadin's lack of mobility and wave control pre-6 by forcing extended trades.
Respect Kassadin R availability; avoid overcommitting when he can Kassadin R in or out.

Danger windows

Avoid engaging without E as missing it leaves you vulnerable to Kassadin's poke and short trades.
Respect Kassadin's level 6 power spike and available R stacks for burst and mobility.
Be cautious if Kassadin has mana for repeated R casts to escape or trade aggressively.

Early game

Force Kassadin to farm under pressure before level 6 by using E to threaten engages and Q to poke.
Avoid extended trades if E is down to prevent Kassadin punishing your cooldowns.
Prioritize level 3 power spike to unlock full Q-W-E trading combo and sustain.

Sylas major spikes: Level 3 for Q-W-E combo, level 6 for R ult if Kassadin ult is valuable, and first AP item completion.
Kassadin major spikes: Level 6 Kassadin R unlocks his mobility and burst, requiring respect.

Win conditions

Use E to engage and force Kassadin into unfavorable trades pre-6, denying his safe scaling.
Capitalize on W sustain and stolen ultimates to win extended fights.
Maintain lane pressure and deny Kassadin farm to delay his level 6 power spike and reduce his threat.
