Challenges are optional activities you can accept for extra rewards. They work like quests and can range from solo objectives to group-based content, depending on the challenge. Access challenges with /ch. From there, you can view available challenges, accept them, and pin active ones to help track your progress.
Challenges are split into daily, weekly, and server-wide categories. Once completed, rewards are placed into your pouch and can be claimed at any time. Rewards persist through wipe, but only for a limited time. After a new wipe, you will have a few days to claim any saved rewards before they expire.
