Can Master Yi get damaged by aoe damage in his Alpha Strike (Q)? Something like Riven R or Kayn Q/W

As far as i know, he cant

I think so, he's intargetable, not invulnerable.

I know that if he has a dot like teemo/cass poison or malz space aids he still takes damage from it, but idk about aoe.

yes he can for some reason, I've died while in alpha multiple times, with his current state i am not sure why this hasn't been updated to be invulnerable in alpha

I can understand, that he gets damage from ticking damage (poison etc) and dies through it but I cant really understand that he "leaves the map" and gets untargetable, but he is somehow targetable for aoe damage ._.
