This is my custom Low Health Screen that I made using only Power Auras addon.. ( And of course photoshop and google too ) (Even the minimap background behind the zone text and clock text if you wonder)
This is to show you how nicely and creatively you can use Power Auras addon what I consider being one of top (If not the very top) useful addon of all times. You can do similar by adding your own textures what is actually really easy as it requires only basic targa editing skills and creativity ofc.. You can find few tutorials on YT..
I am also considering making this "Creation" shareable if anyone would be interested.. All you should need is Power Auras addon..
See the Image here (Ofc its not a final version.. Guess I'll have to tweak it further a bit)
