Stage Guide

6-1 Branching Rules
Nodes Rules
Start
A
  • Meet ANY of the following to FORCE B
    • CA(V)+(F)BB(V)+CV(L/B) ≥ 3
    • (F)BB(V) ≥ 2
  • Meet ANY of the following to go to A
    • Fleet contains SS(V) only
    • Fleet contains AS and meets one of the following
      • SS(V) ≥ 3, no other ship types allowed
      • SS(V) = 3 and DD = 2
      • SS(V) = 4 and CL+DD = 1
  • Go to B if fleet contains no CL and DDs
  • Otherwise, C
B
C
A
D
  • Fleet does not contains AS
F
  • AS Is in the fleet
G
H
  • Meet ALL of the following requirements:
    • Amount of SS(V) ≥ 3
    • Amount of BB(V) + CV(L/B) + CA(V) ≤ 1
    • Pass the LoS check: ≥ 16 (Cn4)
      • Routing becomes random if 12 ≤ LoS ≤ 15.9 (Cn4)
I
  • Meet ANY of the following requirements:
    • Fail the LoS check
    • Amount of SS(V) ≤ 2
    • Amount of BB(V) + CV(L) + CA(V) ≥ 2
  • If the fleet does not contain AS:
    • 15% chance of off-routing to I regardless of LoS check result
H
E
  • Always node E if LoS ≤ 20 (Cn4)
  • If the fleet contains AS:
    • Always node K if LoS ≥ 25 (Cn4)
    • Random between E and K if 20 ≤ LoS ≤ 24.9 (Cn4)
  • If the fleet does not contain AS:
    • Always node K if LoS ≥ 36 (Cn4)
    • Random between J and K if 25 ≤ LoS ≤ 35.9 (Cn4)
    • Random between E, J and K if 20 ≤ LoS ≤ 24.9 (Cn4)
J
K


Tips

  • At least 3 SS(V) are required to reach the boss.
  • There are LoS checks at G H and H K. They do not have high LoS requirements, but an all-submarine fleet without recons/radar can be sent to I.

Recommended Fleets

  • 1CV, 1CL, 1CLT, 3SS(V)
  • Route = C F G H K
    • Has a 15% chance to off-route to Node I
    • Most effective fleet for taking out the boss but it will have to go through node C where there's a Ru-class Flagship.
  • Using a Midget Submarine 
     
     
    on both the CL & CLT gives a powerful Opening Torpedo Salvo (Otorp).
  • For the CV, either:
    • The CV may use several Jets 
       
      , adding the Jet Assault phase to the already strong Otorp, allowing to wipe all pre-boss fleets before they can attack the fleet.
    • The CV should be equipped with a   range extender to be set on Long Range, and so act first after the Opening phases (note that Jets also extend the range to long).
  • Try to use a CVB so that it can attack even in Chuuha.

  • 6SS(V)
  • Route = A D F G H K
    • Allows the fleet to completely ignore any enemy ships that can't attack SSs, however node D is pretty harsh on SS with late-model DDs and flagship CLs.
    • Count on the Opening Torpedo Salvo (Otorp) & cut-in attacks (at boss), so only remodeled SS are recommended when using this composition.
    • Recon seaplanes or Submarine Radars 
       
       
      may be used to meet the LoS requirements.
    • As SSVs have few slots, only one may just carry all the seaplanes. As many combat-capable submarines as possible are needed for this route.

  • 1AS, 1CL, 4SS(V)
  • 1AS, 2DD, 3SS(V)
  • Route = A F G H K
    • The shortest route in terms of the number of battles.
    • 1AS combined with at least 2 SS(V) unlock the "Submarine Touch", a special attack that can trigger several times on the map, consuming a Submarine Supply Material per battle.
    • The AS can equip recon seaplanes to free up slots for the SS(V)s.
    • A trade-off is that any enemy ship still in light damage or better shape at the end of the shelling phase will have fewer targets to launch their torpedoes at, so the AS and its escorts have to tank all the preboss ships that can't perform ASW.

Node I has some good drops like I-401 .

  • To farm here, it is possible to use:
    • 1BB, 3CLT, 1CL, 1CV
    • 1CL, 3CLT, 2CV
    • Route = C F G I
