that black bar is just a backdrop for the runes, for unholy it sort of lights up when you have runic corruption proc. anyway, if you don't want it, just disable the aura "Runes Blood BG" or for unholy "Runes Unholy BG". In your case, you could move the runes on top of the black bar (that's how it is by default, if you don't move it). The icon to the left of Blood Strike only shows when Gorefiend's Grasp is on cooldown. The red bar is an HP bar, I put it in there as an option but disabled it by default. If you want to see it, the aura is "HP bar" and go to "Load" and uncheck "Never". Thanks for checking it out, let me know if you have any other issues.
@reaper7 if you just change those lines then you will still get the other color changes (yellow at max for example). if you wanted a less bright red you could change the line "red, green, blue = 1,0,0" to "red, green, blue = .7,0,0" 1 being the brightest for each color.
