Kassadin vs Vex

Updated May 31, 2026

Overview

Kassadin has low early agency and must survive Vex's high early pressure to reach level 6 safely.
Avoid giving Vex passive lane control by minimizing damage taken and farming near tower early.

Trading pattern

Use Q to absorb magic poke and only trade briefly after level 6 with R for burst and mobility.
Respect Vex's passive fear and avoid trading when it is up to prevent electrocute procs.
Punish Vex if she fails to land fear or uses R aggressively by engaging short trades and backing off.

Danger windows

Pre-6 Kassadin is vulnerable to Vex's passive fear and burst combos; avoid all-ins here.
Kassadin is at risk if he uses R repeatedly without mana to escape afterward.
Vex's R cooldown windows create safer moments for Kassadin to trade or farm aggressively.

Early game

Focus on safe last-hitting using Q's shield to absorb Vex Q poke.
Avoid extended trades before level 6 as Vex's passive fear and burst threaten all-ins.
Preserve mana and health to safely reach level 6 without falling behind.

Power spikes

Kassadin's level 6 R unlocks mobility and burst to challenge Vex's lane pressure.
Kassadin's first major AP item increases his burst threat post-6.
Vex's level 6 R is a strong engage and reset tool to respect during trades.

Win conditions

Survive early lane pressure and reach level 6 to unlock R for short trades and side pressure.
Use R mobility to flank or escape after burst trades, punishing Vex's immobility outside her ultimate.
Deny Vex fear uptime by baiting or dodging it to create windows for aggressive trades post-6.

Tip: For Kassadin vs Vex, read overview, trading pattern, and danger windows first for a fast Mid lane check.
