You pull shadows into a swirling mass inside an empty vial you possess. As long as the vial is open, you are able to use its new contents as 1 ounce of pitch-black ink. If the vial is stoppered, or 1-hour passes, the ink dissipates back into shadow; any writing that has already been made with the ink is unaffected.
