To appeal to a boarder audience from 3.0 and on Crysta will be a craftable item in the game by any DoH, it will be tradeable and sellable in the Markets. A new NPC will be added to the Manderville Golden Saucer where you will be able to transfer your crysta from your character to your MogStation balance, but transferign crysta from the Mogstation to your character won't be possible. The materials needed to craft Crysta will be updated with each patch to maintain the desired level of crafting difficulty of this item.

Additonal note: From 3.0 and on all the gill selling companies are subsidiaries form Square-Enix Co.
