Infinite Undiscovery

Have any character reach IC Writing Level 4. You can use either Savio or Rico for this achievement. (Savio starts at IC Level 3 so if you are using him you can ignore this first part.)

AFTER cutting the chain in Port Zala buy some Papyrus Paper from the general store and write "Talk With Animals" until you reach IC Level 2.(2 Papyrus Paper = 1 "Talk With Animals")

Go back to the general store and buy more Papyrus Paper and Quill's. Write "My Animal Friends" until you reach IC Level 3. ( 2 Papyrus Paper + 1 Quill = 1 "My Animal Friends")

For the next part it is recommended to wait until you arrive in Kolton for the materials needed.

Once in Kolton go to the general store and buy Pulp Paper and Quill's. Write "Animal Secrets" or "Understanding Astrology until IC Level 4. (1 Pulp Paper + 2 Quill = 1 "Animal Secrets" or "Understanding Astrology")
