Kassadin vs Yasuo

Updated May 31, 2026

Overview

Kassadin is a scaling assassin with very high mobility who wants to survive early pressure and reach level 6 safely.
Avoid giving Yasuo passive lane control by maintaining a safe farm position and respecting his medium early agency and lane pressure.

Trading pattern

Trade minimally before level 6, using Q shield to absorb Yasuo's poke and avoid Yasuo E mobility when possible.
After level 6, use R for short, controlled burst trades only when mana and escape options are available.
Avoid trading when Yasuo W (Yasuo W) is up as it blocks many projectiles.

Danger windows

Kassadin is vulnerable before level 6 due to Yasuo's mobility and knockup threat.
Be cautious when Yasuo W is up, as it blocks your Q poke and limits trades.
Avoid using R aggressively without mana to escape, as Yasuo can punish low-mana Kassadin.

Early game

Focus on safe last-hitting near your tower and use Q to absorb Yasuo's magic poke.
Avoid extended trades before level 6 as Yasuo's early mobility and knockup threat are strong.
Preserve mana and health to reach level 6 without falling behind.

Power spikes

Kassadin's major spikes are level 6 R and first completed scaling AP item.
Respect Yasuo's level 2 Q plus E mobility spike and level 6 R if he has knockup access.
Level 11 further strengthens R uptime and damage, increasing his threat.

Win conditions

Survive Yasuo's early pressure and reach level 6 to unlock your mobility and burst with R.
Use short R trades to punish Yasuo when his Yasuo W is down or after he uses E mobility.
Scale into repeated mobile burst and side pressure to outmaneuver Yasuo post-6.

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