Fame quests are quests that require the player to obtain a certain amount of fame on 1 character at once. Once a fame quest is completed, a star is being added to the amount below the character in the classes screen and also to the number in the left-upper corner of the screen when in the nexus. When a player has reached a certain amount of stars, the star in front of their name changes color.
Fame quests:
1 star = 20 fame
2 stars = 500 fame
3 stars = 1,500 fame
4 stars = 5,000 fame
5 stars = 15,000 fame
Fame stars:
light blue star = 0-13 stars
dark blue star = 14-27 stars
red star = 28-41 stars
orange star = 42-55 stars
yellow star = 56-69 stars
white star = 70 stars
