You were zerged down, you can replace that ability with almost anything and the same thing would have happened. A ton of people all hitting you with the same attack at the same time. Even enough light attacks at the exact same time will kill you instantly. There is really not much to explain here, or are you wanting to cry about radiant oppression?
You were zerged by Jesus. Now you will burn in hell!
