Mihoyo introduced a reputation system that lets you undertake additional quests in each region to earn bonus rewards and recipes. The rewards for undertaking these reputation quests make them worthwhile. You can unlock gadgets that reveal treasure chests in a given region, or show the location of the hidden Oculus relics that award you with stamina enhancements and key resources. Unique regional recipe cards can be acquired through reputation quests, as well. Finally, each region awards a unique cosmetic wing-glider you can use to customize your characters, which is a nice touch. Be sure to tackle these reputation quests every week to unlock these rewards.
