Each day Core has daily quests that are available to the player. There are typically seven quests and they will reset once a day.
Core' quests reset at 12:00 am UTC. That is 5:00 pm in Pacific Time and 8:00 pm in Eastern Time. Once they have reset, another seven will take their place. The type of quests depends upon your level in Core. As you level up there will be more variety and challenges. Although the type of quest will change daily, the rewards will remain the same.

If you start a quest before the server resets and complete it after, you can still earn the rewards. It will count during the cycle after the server has reset as the experience is counted at the time of completion.
Rewards for completing quests can vary. At lower levels, these will typically be points, but as you level up, new rewards are added. These can be pieces of armor and costumes for characters or even complete sets. Once a reward is available, players will have the option to claim it.
