The Mad Magic prerequisite states that Bloodrage class feature or the perfect clarity rage power is needed for this feat.
And with this feat you can:
Benefit(s): You can cast spells from any class that grants you spells while in a bloodrage, and you keep your rage benefits when using moment of clarity during a rage.
Now, as a rage prophet (core barbarian + oracle), I don't have the bloodrage class feature, but I do can get perfect clarity to qualify for the feat. I don't have any bloodrage spells, so I won't be able to cast them during rage, BUT, I would be able (with this feat) to keep my rage benefits when using moment of clarity, right? That means I can cast one oracle spell during rage, using the moment of clarity rage power, while still keeping the rage benefits, right?
Looks that way. Isn't that the whole point of the feat?

I think the feat is mostly aimed at Bloodragers, even the Bloodrager spells DC's increase by 1, and that it's a nice, albeit small, incidental use for rage prophets. But if it works, it works, right?
