The Wuthering Waves developers have started preparing us for patch 2.4, which will bring with it an expansion of the game world and new heroes. In particular, we are talking about the cutest Cartesia, which all players already know, as well as Lupa.
The latter has not yet appeared in the game, and the announcement image informs us that this is a character from the next game region - Septimont.
Both girls will likely be part of patch 2.4, and considering they are both 5-stars, it's safe to say that players will have to stockpile a lot of Astrit to get all of the upcoming characters - Chacona, Cartesia, and Lupa.
