In Blade and Soul, quests to save the world are rarely ever complete. Throughout your travels you'll experience a sweeping story of good and evil, and continually make progress toward your goals, but there are some tasks that can never truly be completed. These quests revolve around recurring regional problems, and offer you the ability to continually offer assistance each day for additional rewards.
It's possible to complete 40 daily quests a day, and these can be identified by an infinity symbol overlaying a blue quest marker. This indicates that this quest is available again for Blade And Soul Gold, and can optionally be completed again. You will also want to visit the centrally located Noticeboards—which offer the area's daily quests directly—if you're looking to efficiently take on a number of quests at the same time.
While most daily quests only require you to offer your assistance and complete a task, some are offered by specific faction members, and you'll need to be wearing that faction's clothing to be able to accept them.
While the enemies you defeat during daily quests will sometimes have their own unique treasures, turning in a daily quest can offer a variety of rewards from the quest giver; including gold, XP, consumables, and Valor Stones. Continually completing daily quests can not only be a good source of income, but can also help increase your character's power through upgrades and consumables.
Powerful martial artists know that a job is never done until it's done.
