Suggestion(s)/Comment(s): We should be able to grind Oquilla Sky Crystal and Oquilla Earth Crystal to get their crafting materials back
Details:
now that I finished the PEN Tuvala Weapon to PEN Black Star Weapon and have all 3 of my mainhand, awakening and offhand to Black Star, I don't need the Oquilla Sky Crystal anymore to reform 5 my TET Boss weapon, but I already crafted the Oquilla Sky Crystal, it's probably not just me who have wasted these materials (Oquilla Piece of the Old Moon) and is now trying to upgrade the other pieces of their armor instead,

also main reason is, we are able to grind the Resplendent Boss Weapon Reform Stone V and Resplendent Boss Armor Reform Stone V to their crafting material but there's no reason to do this in hindsight.
