After opening 240 chests and not getting a vial, I can assure you that is wrong.
(Fossil chances are astronomical)

But, getting back to the question:

1) Talk to the alchemist in Kelys. He will give you a Parchment quest.
2) raianezz said the maps needed.

Dont be discouraged if you dont get the Parchments in your first few runs. It took some members in my party over 40 runs.

Good luck!
I'm pretty sure she was talking about the chance at looting the parchments. Btw, 240 is ridiculous amount to loot nothing.
