This guide will lead you through every knowledge from some categories that are quite hard to obtain for the first time. There are two ways of actually getting all the knowledge. The first way is to buy the knowledge from Clara Siciliano, the Bookseller in Calpheon. The second way is by interacting with different NPCs and spending energy or doing a quest chain. The latter option is probably the easier one to do, as you don’t have to spend any silver or much amity.
1. Road of Penitence
In order to obtain this knowledge you will need to be above level 39 and have to visit Calpheon and take the quest A Sinner from the Villager at the square next to Lavientia Batian’s house. Another way for players under level 39: finish the chain quest A Talk with Elion from Annolisa Rosie, make sure to follow previous steps as well. To start the chain quests, talk to Elina Leight in Calpheon.
2. Bell Ringing from the City
Look for the Adventurer in Calpheon outside the inn next to Fredelles Herba. You will get the knowledge from this NPC after finishing quest The Calpheon Bell. In order to do this quest you must be above level 35 and you must have the Apprentice Manager Certificate quest completed beforehand.
