RC7's about to arrive, and all the sphere recipes available in RC7: Fire are in the sphere house already, as well as the recipe (but not stats) for the Seventy-two Forms sphere.

If you want one of each sphere, you'll need:

• War Demon's Blade x 1
  • Craft in RC6

To finish Seventy-two Forms, you will also need 440/400 of each of the remaining elemental stones/omphalos, which will only drop in their respective element seasons. They will almost certainly be used for other spheres as well.

Giselle's materials not listed, if only because I'm not certain where they come from
