This is a video of Bloodreign of Black Dragonflight US soloing Onyxia. This is the world's 5th Onyxia solo as a shadowpriest and the first video of it. This kill was done on December 31, 2008 and took a little over 10 minutes to kill her. I sped up the actual encounter because it seemed kind of boring at its normal speed.
I reccommend all other shadowpriests to try this out for a good challenge. It was very fun for me..
