Charm Casting
Charm casting is using a set of small objects for divination, usually by dropping them on a surface called a map. Both charm selection and map design are completely individualized and don't have to be the same from reader to reader.
A full charm casting gives a lot of information based on how and where charms fall, as well as what's nearby, involving about 40-50 charms. Not all of them will be interpreted - I ignore anything that lands outside the reading area and any upside down charms with a blank back side.
My charm set was selected to answer questions about the best way to proceed in a given situation, so those are the questions that work best for it.
While a full length charm casting is something I always do asynchronously (I go off and do the reading privately, then send results), I can grab and interpret a small number of charms as part of a live reading too.
