Confidence mediumUpdated Jun 10, 2026

Overview

Control mid-range space to force Yasuo into extended trades where poison and repeated (E) excel.

Start trades by landing (Q) or (W) to apply poison, then spam (E) for damage.

Hold (W) until Yasuo commits to dashes to ground his mobility effectively.

Power spikes

Level 6 (R) deters Yasuo all-ins by threatening stuns if he faces you.
First mana/AP item boosts sustained damage, enabling stronger extended trades.
Respect Yasuo's level 2 (Q)+(E) spike that enables aggressive dashes and trades.

Win conditions

Win extended fights by maintaining poison and repeatedly casting (E) while zoning with (W).
Use (R) to punish Yasuo when he commits and faces you, deterring his all-ins.
Deny Yasuo calm scaling by applying pressure and punishing his mobility cooldowns.
