Should be a new stance were depending on the day you can call out a elemental which only protect's you like /cover. Once out it give you certain stat's. I know smn be piss but give them the one's ive seen in abyssea :P

-Proc MP Conserve Trait giving you guarantee percentage of lower cost of spell. Further reduction if align with spell of element of that day.
-Augment's Aspir/Aspir II making monster HP as a reliable draing pool.
-Enhances Refresh Effect.
