Somewhere around kTOS thread. Too much posts to find it again but with a quick search, I found a ‘relevant’ post.
New health values of the three new WB: Blut, Zaura and Nuaele.
Not a definitive proof since I was too lazy to find the actual post but it somehow shows that there will be Nuaele as new WB since they changed his health pool according to this post. Sorry I’m too lazy to search over all the thread haha.
