What Doesn't Yasuo's Wind Wall Block?

Lasers (lux, velkoz ult) and ground targeted abilities (karthus and Cass q) I think.

Hit scan ability's. Any effect that checks inside of an AOE then applys effects.

All projectile abilitys are blocked. Projectile abilitys can be point and click or a skill shot. They generate a Hitboxed animation that impacts on enemy hitboxes.

You can also use this list. https://leagueoflegends.fandom.com/wiki/Projectile

Few things off the top of my head -

- W, R - R - W, R - R - Auto Attacks, R - W - W - R - Q, W, R

Abilities that are not projectiles or go over or under the wall will not be blocked.

Unstoppable abilities such as Vi and Malphite ultimate will ignore windwall also.

Found this on r/YasuoMains

Some of it may be out of date as the post is 2 years old. Some things like Kayle, Akali etc will be out of date due to being reworked

Looking at the interactions with your own champion is best
