Daily Quests
The daily quests that appear in the quests tab are randomly generated from a list of possible dailies. The maximum amount of daily quest rerolls are two per day. The rerolls refresh one per day and the maximum storage of rerolls are two per account. The number of available stored quests is TBA (possibly five or seven).
