Jabes.plays.RPG has raised the question about "reading" people in social situations, particularly through scent.
Scent really should be a derived characteristic, I think.
For crugar: SCENT is LISTEN - 1.
For woffen: SCENT is LISTEN +1.
For bronth: SCENT is LISTEN.
For humans, muadra, and boccord, SCENT is SPOT -2.
Then, to smell something or discern a particular odor, it would be a SCENT check: add/subtract any modifiers to your SCENT, then roll 1d20: equal or less than the target number succeeds.
Tangentially related to the subject are interpersonal relations. For personal interactions, each character has a host of interaction and etiquette skills, which we touched on in part four of character generation. Either interaction or etiquette might be used by a character to persuade someone, for instance. Such checks are done against the character's SOCIAL, modified by their interaction or etiquette modifier.
Interaction is knowing the social cues, body language, and other communication signals for a particular race, so each character has a modifier for human interaction, thriddle interaction, shantha interaction, and so forth. As GM I track these modifiers for you, and you get a large bonus to such checks when dealing with your own race.
Etiquette is knowing the proper way to interact with particular types of people, and can include occupations, social strata, different situations, and residents of different countries/regions. So you have Heridoth etiquette and Burdoth etiquette, as well as caji etiquette, military etiquette, and the like. As GM I track these modifiers for you - the web of modifiers is huge - and you get a large bonus when dealing with your own occupation, social position, and region.
