There are two types of events: Limited Events and Daily/Training Events.
Some Quests may only be attempted a limited number of times each day.
*When "Attempts" is displayed, all Quests on the same screen share that limit.
*Attempts are reset each day at 12:00 a.m. (PST). For example, the EXP Chamber Quests (ranging from Novice to Advanced) can be challenged a total of three times each day.
There are also daily campaigns held each day.
*The Gil Chamber and Ore Chamber campaigns held on Saturdays and Sundays are different from those held between Monday and Friday.
