Debate
Debate is a foundation of Hermetic society, most prominent in the great legal and political debates at Tribunal. It can also be of great importance in other settings, such as a university, court, or so on. In most sagas, debate is probably handled on-the-fly, using roleplaying and the storyguide's arbitration.
HoHS 90-93 offers formal rules for debate, including the use of debate at Tribunal. These rules allow one to employ several combinations of social skills, following mechanics that are reminiscent of combat or certamen. The relevant social abilities are Folk Ken, Intrigue, Artes Liberales, and Charm, Guile, and Leadership.
