As Version 2.1 ofWuthering Waveshits servers, it brings players new quests, new storylines, and two additional regions. The Riccioli Islands and Vault Underground are two additions to the map in Rinascita, and the two of them are vastly different from each other. Unlike the free spirit thatencapsulates the Riccioli Islands, Vault Underground has been said to imitate a prison.

The location is underneath the Averardo Vault, andWuthering Wavesplayers can only unlock it by completing theSilent As A Falling Leaf Quest. This exploration quest is quite heavy in comparison to the other exploration quests inWuWaand requires a lot of running due to the numerous levels of Vault Underground.
