What's the use of masks for ghosts?

Ghost face is a costume prop, without any attribute bonus. Players can exchange their collections.

As long as you walk through the activity mode once a day, you can get 1 ghost fragments, and you can get a permanent ghost mask by collecting 10 fragments. Ghost face is not only domineering in name, but also handsome in equipment. It should be noted that mask fragments will not be distributed to the warehouse. Players who don't see any fragments in the warehouse don't have to worry. As long as they pass the active mode, they will get fragments. Debris progress can be viewed on the activity page, and permanent ghosts can be obtained by directly collecting 10 masks.
