The Witches Runes are different from the Elder Futhark Runes in that the Witches Runes are not an alphabet. The Witches Runes are instead a series of symbols that can be used in divination. There are different versions of the Witches Runes, one uses 8 symbols, another uses 10 symbols and the one discussed here uses 13 symbols. Cast the Witches Runes the same way your would the Runes.
The 13 witches Runes in divination
You can cast the Witches runes on a cloth, or on the table and read the meaning of the runes that are facing upwards only. If the eye is amongst the runes look at where the eye is looking. If there is a rune in front of the eye then this is the rune you must pay extra attention to.
You can also read the Witches runes by picking on rune at a time while you ask the runes a question.
