Yes, that’s exactly how I would do it! I’d also use it for Challenge Level if unsure. Great idea, that’s going for tips and options for sure.
I think the thing that threw me off a little bit is that Oracle 2 seems patterned in someway off the Fortune Roll but the wording is a little different. The Fortune Roll assumes that a high result (6, critical) is in the player's favor and each tier lower is less favorable. Depending on how you "ask" Oracle 2 your question a high result might be really bad for your character - so - it just takes a moment to think about how to frame the question.
