When you start the game, you will be introduced to the Request Board.
This board will have requests or odd jobs from the citizen or the community, this is initially your biggest source of income in the game. As you progress through the story and increase the Guild Rank, you will receive more requests. The requests fall under the D, C, B, A, and S Rank categories, increasing the difficulty of the quests where D is easiest and S is the hardest.
Some of these requests are repeatable and you will see a (- 1, – 2, ….- 10) beside them, when you fully complete a request you will see a “Completed” red stamp on the request, though you can still repeat it to get the items listed.
There are 4 types of Requests “Rescue”, “Wanted”, “Search”, and “Subdue”, where the later is usually a repeatable request and during these Subdue quests there will be random occurrences such as new Purple Gathering points, new Chests and Rare Monster sighting.
