Kayle can ult Kog's passive
Our Kayle managed to ult me (Kogmaw) after I had already died. It may have been a freak timing thing, but it's pretty wrong. I should note that Karthus & Yorick were on the other team, though neither of their death effects were going at the time.
I do not know if there was anything damaging me through the ult, it seemed more like I died right as Kayle cast it.
