Tips

This map requires your fleet to have a certain amount of Line of Sight (LoS) in order to route to the boss.

    • Fleets routing I O need LoS ≥ 34 (Cn1).
    • Fleets routing J O need LoS ≥ 49 (Cn1).

Recommended Fleets

There are 3 main routes you can use:

  • The middle route is the preferred route used for clearing since it allows for 1CV and 1CVL to be brought, enabling powerful opening airstrikes.
  • 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.

  • 1CV, 1CVL, 1CL, 3DD (Fast)
  • 2CVL, 1CL, 3DD (Fast)
  • Route = C E I O
  • 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 airstrikes.
  • Ensure that you meet LoS ≥ 34 (Cn1) to route to the boss node.
  • Carriers should be equipped to utilize CVCI to maximize accuracy and shelling power against the enemies at the boss node.

  • 1BBV, 3CA, 2CAV/CL, each CAV/CL need to carry 1 Drum 
  • Route = B F J O
  • All enemy compositions before the boss do not have any air power making it easy to secure Air Supremacy (AS+) with just 1 Seaplane Bomber on a CA(V) or BB(V).
  • Artillery Spotting should be used to increase the likelihood of reaching the boss node.
  • Ensure that you meet LoS ≥ 49 (Cn1) to route to the boss node.
  • 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

  • 1CA(V), 1CL, 4DD (Fast)
  • Route = B F E I O
    • Ensure that you meet LoS ≥ 34 (Cn1) to route to the boss node.
  • This composition is recommended to be used when attempting to clear the monthly quest Bm7 (only a CA and not CAV can be used in this case).
    • This route is difficult without access to ships that are able to equip SPF/SPB to gain some air power.
    • Zara Due is an ideal choice, being an SPF/SPB capable CA with a large first slot, ensuring that the SPB can survive until the boss node, potentially securing AS+. You may also include an SPF to ensure that you are able to secure AS on boss formations that contain a carrier.
    • Otherwise any single CA or CL able to carry SPB/SPF 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 can help to reach the boss node consistency.
