Le Sorcier met la Zizanie (fan expansion for Les Charlatans de Belcastel)

This expansion does not change the basic game. It is a supplement that is played between the potion preparation phase and the scoring phase.
"The wizard takes a dim view of the activity in the bazaar of Belcastel.
His servants discreetly slip enchanted scrolls
into the Charlatans' belongings.
While trying to prepare a potion, a Charlatan reads one of the recipes tampered with by the Wizard.
The unpredictable consequences ripple out to the other Charlatans and stir up trouble among them."

This expansion allows for more interactivity between players. It is compatible with the official expansions but they are not required.
