The Star Wave Brush was filled with the Star Liquid that was used to craft the star runes. It was kinda similar to the the one to make Talismans.
Appearance[]
It was a bone pen that was about the thickness of a finger and half a foot long. It had a sharp end and seemed to be made from the teeth of some kind of scaled beast, with a thin, thin hole in the middle. The other end of the tube looked like a transparent bag, with some silver-colored liquid inside, emitting waves of celestial energy.
