So, someone got the demonic formula via bidblast.
I paid 45mil and a nightmare scarf to get it (to clear the rumors.).
I gave it to a friend who i'm not naming via their request so dont ask.
The friend is sending me a screenshot of each level's formula as they go along.
I will list the formulas and the wings MP here.
Wow props to you and your friend, I wish I had gotten it though I wouldn't be able to level it up that fast anyhow...
Still that your friend openly shows us the progess of the demonic quest is definitely appreviated
