"At the beginning of a session if a PC is hanging around Ye Olde Village Inne with nothing better to do, they can roll 1d6 and spend 100gp times the roll on liquor and/or lechery. The character gains experience equal to the gold spent. The d6 x 100 standard applies to villages only. A PC could travel to a town or city and debauch much more efficiently. Towns are worth d8 x 150 gp/xp and cities d10 x 200. The city of Hautville is worth d12 x 250 owing to its extreme wickedness."
