The most common method of taking an omen in ADF rites is through the Drawing or Casting of Lots. This method involves a collection of symbols, commonly from a writing system, from which the Seer picks from, and then interprets. The most common symbol sets we see in our rites are Rune, Ogham, and more recently, the Greek Alphabet Oracle. However, many folks are more comfortable with tarot or oracle decks and use those without issue. For the purposes of this course it is suggested that you choose a historical, closed system of divination.

The Runes of the Elder Futhark is a writing system for the Germanic people. Each symbol stands for a letter/sound, as well as additional divinatory meanings.

The Ogham was a system of writing for the ancient Celts , though it is found most commonly in Irish. Each symbol represents a letter, since the ogham was likely first used as a writing system rather for divination.

The Greek Alphabet Oracle comes from the Ancient Greek system of writing. Unlike other symbol sets, where a collection of key words may accompany each symbol, the Greek Alphabet Oracle has a phrase that matches to each symbol. The phrase starts with a word that begins with the corresponding letter.

Another less well-known, or at least less widely used in modernity, method of divination is haruspicy. This is diviniation through the reading of entrails. In modern times there are a variety of ways that one can do this without killing a live animal in ritual (which is generally frowned upon, and specifically disallowed in an ADF rite).
