Unit Frames

[Kayla5454]

I was watching a druid video on the Void Reaver fight and he had raid frames that were translucent except for the health bars of the players within range. This made it very obvious who could be healed. Does anyone know what mod this is?

here is the link to the video. http://stage6.divx.com/user/Bufe/vid...ranceFirstKill
