Quests are tasks offered to players for them to complete to gain rewards: gold, exp, unlock a skill, or simply to progress the story of the game. The task can be in the form of kill quest, gathering, or errand quest. Quests are separated into 3 categories: Main Quest, Secondary Quest, and Repeatable Quest. Main Quest is related to the story of the game, so it is mandatory - while Secondary Quest and Repeatable Quest are optional.
