Zephyra:
There's so much we don't know about in the Material Realm. They require us to pay with Adena for everything.
So I started my research with Veruti. I also got help from the spirits. Research was hard, but then we discovered a new skill that can save Adena by creating valuable goods.
So, do you want to join my research? By the way, only Lv. 40 or above Ertheia who have completed their 1st Liberation may learn Alchemy.
