final update:
This is the last update to the document, the reason is I don't have much time to keep datamining and also I quit the game.
If you are unable to find new sources for leaks, try NIKKE Community Discord (ENG), NGA (CN) or Arcalive (KR).
I will continue to update the Bond Advise Guide because it doesn't take me too much time.
Thanks for all!!!
