This page will contain information about the new Multi-Deck feature that NPCs will have and how we can use what information may be available to us to predict which cards and NPC might have in its deck.
So far we believe that each NPC will be assigned a fixed number of decks of cards and that which deck will be used will be determined randomly at the start of the Parley.
The decks of cards assigned to each NPC will include cards selected from the full list of NPC cards based on the NPC's Station, Race, and Demeanor, as well as cards that will be available to all NPCs. i.e. some cards might only ever be played by Academics but never by Soldiers, and others might be solely available to the Vulmane. When you first hail an NPC it is supposed to be possible to determine its Demeanor from the initial text displayed.
More to follow... once we know more :-)
The following is transcribed from the Civic Diplomacy tutorial in-game:
"One other aspect to Stations is important: NPC decks. When you approach an NPC for a Civic parley, their Station should tell you something of what you should expect their strategy to be.
Firstly, remember that this is a general guideline, but you will find it true in many cases.
Each race, as you may have already noticed, favors one Expression type and bases the bulk of their strategy on it. This is not a hard rule, but is a very widespread guideline.
Humans, for example, favor Inspire as an Expression type. If you were to engage in Civic parley with a Human Noble, their deck would be composed (mostly) of Inspire and Flattery." (Likewise, a Human Soldier's strategy would consist of Inspire and Demand.)
The pages for Station and Races present this information in a more tabular form, although keep in mind that the Races page includes all information about a race, not just information related to Diplomacy.
