We've resolved a critical issue where players might not receive blueprints and materials after defeating the arena boss. A hotfix has been released to address this. Upon logging in, if you've already completed the task, the blueprint, materials, and armor will be automatically reissued. If you haven't completed it, you can earn the rewards by defeating the boss again. For any other issues encountered during gameplay, please visit our community for support and feedback. Thank you for your continued support!
