Part 1: Monsterpedia
This is the Monsterpedia. Every monster and NPC in the game has 2 monsterpedia entries. The first one is unlocked simply by meeting or killing them. The secret entries are unlocked in several ways. About half of them are obtained by collecting lucky dolls. The others are collected by killing their corresponding monster a specific number of time. I didn't bother collecting all of those because it is a horribly boring grind that would takes hours to do.
