Hey, hello what addon is this one http://youtube.com/watch?v=dSzevufYemI, the one that makes the hp/mana bars to be around the undead.

The frames are X-Perl im guessing but the Health and Mana bars around the person that looks like this: ( ) are called ArcHUD

Thanks!

Fidda is correct. Xperl for the unitframes and the hud is ARC. DHUD is similar but you can tell it's ARC because it tends to be more round.
