If a barbarian dips into the warpriest class or vice versa, would she be able to use her warpriest blessings while in rage? They aren't spells, they are supernatural abilities (but sometimes they replicate the effects spells). They don't ever require concentration checks as far as I know.
I'm interested in how rage affects all blessings, but most interested in how it interacts with the liberation blessing:
Liberation Blessing
Liberation (minor): At 1st level, for 1 round as a swift action, you can ignore impediments to your mobility and effects that cause paralysis (as freedom of movement). You can activate this blessing even if you’re otherwise unable to take actions, but not if you’re unconscious.
Freedom’s Shout (major): At 10th level, as a swift action you can emit a 30-foot aura that affects all allies with the liberation blessing described above. This effect lasts for 1 round.
