Airchmomancy is thought by some to have been a pre cursor to Acultomancy (divination via needles). In this form, any pointed object could be utilized to divine the future. The objects used could be anything from needles to stakes.
The practitioner would take any object with a point, drop it on a flat surface and predict a future event by interpreting the pattern made by the objects.
