Full lethality Rhaast

So I played Kayn yesterday, got camped by their mid and jungler, 1/4 at about 6 mins in; I sit under turret and farm, poke Nasus for transformation bead things; transform, then walk into a 1v3 and pull this malarkey, Nasus and I were dying of laughter the whole game cause I had been doing this for like 20 mins at this point, but not to that extent.

EDIT: if you listen to me hit my E after flashing to W Riven I'm pretty sure you can still hear Kayn talk and Rhaast responding (I don't think Kayn is supposed to talk when you're in Darkin form)
