Can a shugenja use commune with spirits to ask multiple questions of a kami? the Options say: "If you succeed, receive one additional boon per option spent this way.
Each boon can only be received one time per activation." That seems like it's saying that if you ask for a detail about the location, say, "Hey, kami, who killed this guy?" you can't spend options to ask a second question.
Of course, now that I look at that section again, I'm not seeing a restriction of one ritual per narrative scene like they impose on invocations, so maybe it isn't an issue.
