How many types of duty can a character start out with? I have a player in my campaign that used his character's 10 starting duty by choosing 2 duty types (5 points in each). He says the rules allow this and I didn't press the issue at the time during our roll20 session. Reading the AoR rules, I tend to lean that a PC can only have 1 type of Duty, but the book doesn't directly state so, at least not clearly for me.
Along the same lines, would a PC be able to have more than one type of duty further into a campaign?
