I don't believe we've gotten clarification on that. Best guess would be that Lydia moves to 882 stars
I think that is what they have aluded to, though I may have only heard conjecture from others... guessing we will know soon, with ninja released I'd imagine the faction should open very soon?
The game already answered this question few months ago in an interview.
When Shadowkin Faction release, Lydia points will change.
Cirilla (General Manager) gave a direct response.
A player told Cirilla will Lydia star number change when Shadowkin is released.
Cirilla gave a point blank answer: YES
Thier is no clarification error or misunderstanding.
Lydia star amount will change from 819 to 882.
I don't feel like searching for the youtube video.
You can search for the youtube video yourself if you want to hear Cirilla say it.
The Game wants Lydia to be the end reward for All Faction War Crypts.
Cirilla, has 1 of General Managers representing the game, told players what will happen.
This is why players have tried rushing to finish Faction Wars before the change to Lydia.
They told players we had few months to get Lydia before change.
The few months have pasted - The release of new Shadowkin Faction is probably near.
