Sorry if this has been covered already, but the search function is clunky, at best.
Anyway, I was going over the rules as a refresher the other day when I noticed a discrepancy (or at least I think) in the rules for using social skills like Charm, Intimidate, etc.
When you read the description of each social skill in the Skills chapter, they essentially say "Make a Test to influence NPCs". The Command skill, for example, states that a successful Command Test indicates that NPCs under your authority follow your instuctions, where a failed Test means they misinterpret your orders or do nothing. Based on this, it seems that social skills are pretty simple; make the Test, and the NPC will react based on whether you succeed or fail.
However, in the Interaction section (p.230 of chapter VIII) they make it look like an NPC will do what the player wants 50% of the time, and that they must of at least Indifferent disposition. Also, this percentage will increase or decrease based on their disposition, so that a Devoted follower will obey your commands 70% of the time. The social skills are only used to change an NPC's disposition, thus increasing the chances that they would listen to the PC's, and the difficulty of the test is influenced by the NPC's current disposition.
So all of this leaves me confused. Which one is it? If an Acolyte wants to instruct the local militia to look into a local gang with the Command skill, does he simply do a test with a pass/fail outcome, or is there simply a chance that they'll do what he wants based on their current disposition (which could be improved with a Command Test)?
Furthermore, what skill would be most appropriate when the players are tying to convince an NPC of something? They're not lying, but the NPC simply doesn't believe them. How would they go about changing their mind?
Thanks for any input!
