Crystal Ball

Crystal balls are an ancient form of divination. Scrying with a crystal - spheromancy - is a specific form of crystallomancy (also known as catoptromancy). Crystallomancy refers to scrying using any reflective surface, such as a pool of water in the moonlight or a polished mirror. The more you use it, the more attuned it should become to you - and you to it. Similarly you should keep your crystal carefully wrapped and stored when not in use. Do not leave it "on display". It's not an ornament, it's a divination tool made in flawless crystal. Treat your crystal ball as special and it will give you special visions when you ask it questions.
