Charlatans are fair and carnival wizzards specialized in entertainment and illusions
Most charlatans have Magery 0 to 2 if they would have had more they would probably have been discovert by some talent scout and got a scholarship at some Academy. If they have higher Magery it is often limited to one college or crippled in some other way.
Charlatans have a similar representation as Wizzards and in fact their are those who actually studied at some guild academy but had to leave. Therefore they use Ritual Magic with Thaumaturgy as root. They mainly learn Illusion, Light & Darkness, and Sound Spells.
Charlatans are travelling people and as such have a low social standing (probably a Status -1 or 0), but might have a fanatstical reputation. Most charlatans are Poor or Struggling.
Some charlatans use Wizzard's bowls or christal balls. See Guild Wizzary for detail.
