The term 'Uses a Crystal Ball' can be summarized by two crossword solutions: 'Scries' (6 letters) and 'Gazes' (5 letters). Scrying is an ancient practice of divination, or predicting the future, using a crystal ball. It involves gazing into the crystal ball and interpreting the visions that appear. Gazing is similar to scrying, but instead of looking for visions, the practitioner focuses on the energy of the crystal ball itself. Both practices are used to gain insight into the future.
