It's an on-hit effect so it shouldn't proc ludens or rylais
So his Bleed before this did.
Also Activate W is a Empowered attack. If it does not kill then it adds the on-hit. I could see the second part not applying but the activate should definitely apply all of these.
Also Twisted Fates E does and its on-hit and it does.
