Tips

Regarding the map

Once the map is cleared, it no longer possible to roll the final boss form.

  • Only AVs, CLs, CTs, and DDs are allowed to sortie!
    • Specifically at least 1AV, 1CL, and 1DD. CLT cannot be used here.
  • Maximum of 2AV allowed.
  • Maximum of 3CL/CT allowed.

Node notes

  • Node C is a normal submarine node
  • Node B is a submarine node that sometimes contains surface ships instead of submarines
    • Regardless of enemies present, B is treated as a Submarine node for  /  consumption
    • The only reason to head towards B is to have a fleet that cannot/doesn't want to face SS So-Class Elite at node C but at the cost of an extra surface node
  • A CL Tsu-Class Elite can show up at node E.
  • Node G can be guaranteed with 4 DDs in the fleet.

Recommended Fleets

AVs and CLs able to carry a Midget Submarine 
 
 
are advised in every composition.

  • Because you can only deploy AV/CL/CT/DD, it is unlikely that your fleet win during daytime battle. You should expect the battle to last into nighttime.
  • Using Seaplane Bombers on your AV's biggest slots can help you achieve AS and Artillery Spotting.

  • 2AV, 1CL, 1DD, 2CL/CT/DD
  • 2AV, 3CL, 1DD
  • Route = A C E F H J
    • Has the highest damage output at the boss, especially since the boss fight almost always requires night battle.
    • Needs to fight an extra battle against a fleet led by a CA Ne-Class Elite

  • 1AV, 1CL, 4DD
  • Route = A C E G H J
    • The most cost-effective way to get to the boss, and guarantees G branching, which allows two air reconnaissance rewards.
    • The setup with the lowest damage output. It may not consistently get a victory at the boss.

  • 1AV, 2CL, 3DD
  • Route = Random:
    • A C E G H J
    • A C E F H J
    • Has better damage over the Light fleet, and on the shortest route, can fight at the boss with better damage output.
    • Has to deal with RNG. Being sent to Node F may hurt a bit more.

Air Reconnaissance Mechanic

On Nodes G and H, Seaplanes will be flown towards the "green X" (the recon route is shown on the map as green arrows).

  • Successful reconnaissance will reward additional resources upon getting a B+ rank on the boss.
    • Neither G or H have combat.
    • Animation will be shown for the Air Reconnaissance; if both   Large Flying Boats 
       
      and other   Seaplanes (SPR and SPB) are brought, Flying Boat animation takes priority.
    • Success rate of the air reconnaissance depends on the LoS and Seaplanes count.
    • All reconnaissance rewards are forfeit if the fleet fails to win at the boss node J.

The formula for Air Reconnaissance is:

Air Reconnaissance Success Formula
[math]\displaystyle{ R = \sum_{\text{SPR ; SPB} } \text{LoS} \times \sqrt{\sqrt{\text{Plane}_\text{Count} } } + \sum_{\text{Flying Boats} } \text{LoS} \times \sqrt{\text{Plane}_\text{Count} } }[/math]
With
  • [math]\displaystyle{ \text{LoS} }[/math] is the base LoS   of the plane without fit bonuses.
  • [math]\displaystyle{ \text{Plane}_\text{Count} }[/math] is the remaining amount of planes in a slot.
Notes
  • The minimum "[math]\displaystyle{ R }[/math]" to achieve success is 12 for G and 16 for H.
  • For Great Success, the requirement is
[math]\displaystyle{ R_\text{GS} = R \times (1.6 + rand(0 ; 0.6)) }[/math]
  • This means that the minimum and maximum requirement for Great Success for H is 25.6 and 35.2.
 
Air recon success shown after boss node win

To sum up, the more LoS and Seaplanes used, the better, with Flying Boats counting for more than other seaplanes.
