Overview
Conversations are the interactions between player characters and Civic NPCs during Civic Diplomacy. The five conversation types are: Convince, Entertain, Gossip, Incite and Interview. All conversations except Interview block one type of expression during a parley. Not all conversations are available in each town, depending on the race of the town's residents. Faction and prestige gains as a result of Civic Diplomacy are affected by the conversation. The conversation type also influences the rewards (information and city buffs) for a successful parley.
