Rhabdomancy
Rhabdomancy is a divination technique which involves the use of any rod, wand, staff, stick, arrow, or the like.
One method of rhabdomancy was setting a number of staffs on end and observing where they fall, to divine the direction one should travel, or to find answers to certain questions. It has also been used for divination by arrows (which have wooden shafts) - otherwise known as belomancy. Less commonly it has been assigned to the I Ching, which traditionally uses a bundle of yarrow shoots, and also dowsing, which often uses a wooden stick.
