This spell casting gauge is T.Kings artwork that I tailored to my needs by making it dark and creating a new flipped version of the spell casting gauge. I also cleaned up the graphic so that it is more solid and does not have the jagged look in game.
This window is special in the sense that it uses two arcane spell casting gauges facing the opposite direction. As the preview image illustrates, the gauges can be used stand alone or with the target window that I created. (See the download target section for more details)
