Just a mistake copy/paste - that's the Cassia Block & Unending Journey up in the Carpenter's section.

Though I do want to clarify:

Oriental Grass -

Oriental Grass x2
Growth Formula Theta x5
Water Crystal x5
Lightning Crystal x5

Seems like you're spending 2x Oriental Grass and some other mats to make 1x? Is that a mistake in the name, or is there an Oriental Grass furnishing item *and* and Oriental Grass component, I wonder?
