Kill video of my guild vs Netherspite, second to last boss of Karazhan (excluding Nightbane). Taken from a priest perspective. Watch our noob warlock drain-tank go down to a void zone in the first thirty seconds of the fight :p

--* SONG INFO IS IN THE CREDITS! *--

Since I've had a lot of questions about this, these are the main mods that I use that you see in the video:

Playerframe/Target Frames: Xperl
Raidframes: Perfectraid
Buffbars: Morganti's
Actionbars: Bongos.
