For this achievement you will have to write "Will of the Universe". To write this you will need to get Savio to IC Level 6 and must complete the Writing Upgrade Quest (available once you load your endgame save).
Head to Port Zala and talk to Rico on the beach to start the quest. He will ask you to bring him some different materials:
2 Clerks Quill, 1 Genius Quill, 2 Lunatite, and 2 Armalista
Armalista and Lunatite can be bought from merchants if you download the free "A" voucher.
Genius Quill can be forged by Seraphina or found in some treasure chests.(To forge you will need a Dragon Fang, which is dropped by Dragontail Vipers in the Luce Plains section of the Seraphic Gate, but you must get a Player Advantage on them. and a Pius Wood, which is dropped by the Gigas's found on the Graad Woods section of the Seraphic Gate and is a very common drop.)
Clerks Quill can be forged by Kiriya. (To forge you will need 2 Writers Quill which can be bought at the Kolton General Store, and 2 Placidus Wood, which is dropped by the Lumpers in the Bihar Mines section of the Seraphic Gate)
After collecting these materials head back to Port Zala and talk to Rico again to finish the quest. You will now have new recipes available to Savio, including the book "Will of the Universe".

1 Memoirs of an Alchemist.
Can be found in treasure chests (check ones behind rocks that Gustav and Balbagan can break). or can be forged by Savio.
