Dark Water Clover

"Gasp!"

I was wallowing in disappointment as I opened one storage compartment after another found nothing that I needed when I heard the gasp from Elina and immediately appeared beside her with my heart beating excitedly.

"What did you find?" I asked as I appeared beside her, "This," She said, pointing at the clover-leaf, which looked to be made of black water with stars twinkling on it.

"Dark Water Clover," I said slowly with wonder in my eyes. 

The Dark water clover is an extremly rare resource that even old monsters will fight for; it is a resource at the same grade as the divine crystals and the resin I am searching for, but it is not the resource that I could use for my core formation.
