Tips

  • You are required to sink the flagship at boss node 4 times to clear the map. The reward for clearing the map is 100 points and a medal. Boss's HP Bar will reset at midnight at the beginning of each month.
  • This map requires your fleet to have a certain amount of Line of Sight (LoS) in order to route to the boss. It uses Formula 33 (F33) to calculate the LoS of your fleet to determine if you meet the LoS check.
    • Fleets routing from I-O requires Cn1 = 34
    • Fleets routing from J-O require Cn1 = 49
  • Akashi can drop with a small chance in 2-5, but only for Admirals who have do not have her yet in their base. If you already have her, she will not drop in this map anymore.


Recommended Fleet

  • There are 3 routes you can go
    • The middle route is the preferred route used for clearing since it allows for 1 CV and 1 CVL to be brought, enabling powerful opening air strikes.
    • The top north route should be considered for clearing quests such as Bm1, it can also be used for clearing despite the high cost
    • The north-middle route should only be used for clearing quests that banned heavy ships and only allow up to 1 CA(V) such as Bm7


Middle route C-E-I-O: 1 CV 1 CVL 1 CL 3 DD / 2 CVL 1 CL 3 DD (All Fast)

  • Attention should be given to fleet ordering to ensure you maximize for day battle performance.
  • Use CV(L) that are able to perform strong opening air strikes.
  • Ensure that the fleet speed is fast.
  • Ensure that you meet the required LoS to route to the boss node (>= 34 Cn1)
  • Carriers should be equipped to utilize CVCI to maximize accuracy and shelling power against the enemies at the boss node.


Top north route B-F-J-O: 1 BBV 2 CAV 3 CA (each CAV carrying 1 drum canisters)

  • All enemy compositions before the boss do not have any air power making it easy to secure Air Supremacy (AS+) with a minimal of 1 Seaplane Bomber (SPB) on a CAV or BBV.
  • Artillery spotting should be used to increase the likelihood of reaching the boss node.
  • Ensure that you meet the required LoS to route to the boss node (>= 49 Cn1)
  • This composition is recommended to be used when attempting to clear the monthly quest Bm1.
  • The boss formation is random between 3 Ru class battleships or 2 Ru class battleships and 1 Wo class carrier. You are required to bring more seaplane bombers if you wish to secure AS at boss as well


North-middle route B-F-E-I-O: 1 CA 1 CL 4 DD - Fast Fleet

  • This composition is recommended to be used when attempting to clear the monthly quest Bm7.
  • Ensure that you meet the required LoS to route to the boss node (>= 34 Cn1)
  • This route is difficult without access to ships that are able to equip seaplane bomber or seaplane fighter to gain some air power
    • Zara Due is the ideal choice due to her large first slot ensuring that the seaplane bomber can survive until the boss node and potentially securing AS+ against the triple Ru-class battleship formation. You may also wish to include a seaplane fighter (along with the seaplane bomber) to ensure that you are able to secure AS in the event that you face the boss formation that contains a Wo class carrier.
    • Otherwise any single Zara or Agano class with a seaplane bomber will be sufficient to secure Artillery Spotting for the pre-boss nodes.
  • Please note that as your fleet for this route is pretty light, there is a good chance you will get heavily damaged before reaching the boss node. Sparkling is recommended for boss node reaching consistency
