This is a sub-page of Ragnarok Online/Changes.
Various texts for each class in the beginning had a rough translation from Hangul to English. Some Job Quests interestingly refer to the players by their genders that remain unused as of Episode 18. The Thief Job Change Quest in Episode 2.5 loosely references the Alignment System and how leaning towards Righteous/Fame would unlock additional dialogues with the quest starters.
Episode 18 deleted quest requirements for certain jobs, such as the Magician's Mixing Table where the player had to collect a type of solution specified by the Guildmaster to create a solvent, and Archer's Trunk collection for points.
