Curiosity: Coal Drawing

[ZantetsukenX]

Just an idea I thought of as I dropped 500+ coal from my coal pits into the ground. Would be nice to get a curio that used them. Came up with Coal Drawing. Have it use Coal + Parchment. Or Maybe Coal + Stone and call it a cave drawing.

Hopefully if it used parchment it was actually be an okay LP/HR with a sub 10 mental weight since both Coal and Parchment require items that take time to make.
