===Tips===
====Regarding the map====
Requires 4 Boss kills to deplete the HP gauge.
*Once the map is cleared, you can no longer roll the Final Form at the boss node.
*'''Only AVs, CLs, CTs, and DDs are allowed!'''
**Specifically at least 1AV, 1CL, and 1DD. CLT cannot be used here.

====Node notes====
*Node {{MapRoute|C|red}} is a normal submarine node
*Node {{MapRoute|B|red}} can be a submarine node, but isn't always.
**The only reason to head towards {{MapRoute|B|red}} is to have a fleet that cannot/don't want to face [[Submarine So-Class#Elite|SS So-Class Elite]] at node {{MapRoute|C|red}}. But doing so requires an additional fight which is not preferable.
*A [[Light Cruiser Tsu-Class#Elite|CL Tsu-Class Elite]] can show up at node {{MapRoute|E|red}}.
*Node {{MapRoute|G|green}} can be guaranteed with 4 DDs in the fleet.


===Recommend Fleets===
AVs and CLs able to carry a {{EquipmentLink|Type A Kouhyouteki|Type C Kouhyouteki|Type D Kouhyouteki Kai (Kouryuu Kai)|text=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 SPBs on your AV's biggest slots can help you achieve AS and Artillery Spotting.
*Consider using special night cut-ins on your DDs to damage the boss during night battle.

<tabber>
|-|Light fleet=
*'''1AV, 1CL, 4DD'''
*Route = {{MapRoute|A|blue|C|red|E|red|G|green|H|green|J|red}}
**The most cost-effective way to get to the boss, and guarantees {{MapRoute|G|green}} branching, which allows two air reconnaissance rewards. 
**The setup with the lowest damage output, that may not consistently get a victory at the boss.

|-|Medium fleet=
*'''1AV, 2CL, 3DD
*Route = Random:
**{{MapRoute|A|blue|C|red|E|red|G|green|H|green|J|red}}
**{{MapRoute|A|blue|C|red|E|red|F|red|H|green|J|red}}
**Has better damage over the Light fleet, and on the shortest route, can fight at the boss with better output.
**Has to deal with RNG, and being sent to Node {{MapRoute|F|red}} may hurts a bit more.

|-|Heavyer fleet=
*1AV, 1CL, 1DD, 3AV/CL/DD
*'''2AV, 3CL, 1DD'''
*Route = {{MapRoute|A|blue|C|red|E|red|F|red|H|green|J|red}}
**The highest damage output at the boss, especially due to the boss fight almost always requiring night battle.
**Needs to fight an extra battle against a fleet led by a [[Heavy Cruiser Ne-Class#Elite|CA Ne-Class Elite]] which has battleship-like stats.

===Air Reconnaissance Mechanic===
On Nodes {{MapRoute|G|green}} and {{MapRoute|H|green}}, recon planes 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 '''winning at the boss node'''(B rank or higher).
**Neither {{MapRoute|G|green}} or {{MapRoute|H|green}} have combat.
**Animation will be shown for the Air Reconnaissance; if both {{Equipment/Link|Type 2 Large Flying Boat|PBY-5A Catalina|text=Flying boats}} and other seaplanes are brought, Flying Boat animation takes priority.
**Success rate of the air reconnaissance depends on the LoS and slot sizes of Seaplanes brought.
**'''You forfeit all reconnaissance rewards if you lose at or do not reach the boss node.'''.

The formula for Air Reconnaissance is
<math>R = \sum_{\text{Seaplane Recon, Bombers}} \text{LoS} \times \sqrt{\sqrt{\text{No.}_\text{planes}}} + \sum_{\text{Large Flying Boats}} \text{LoS} \times \sqrt{\text{No.}_\text{planes}}</math>

To sum up, the more LoS and Seaplanes you have, the better, with Flying Boats being better than other seaplanes.

*For node {{MapRoute|G|green}}, the minimum <math>R</math> to achieve success is 12 for {{MapRoute|G|green}} and 16 for {{MapRoute|H|green}}.
*For Great Success, the requirement is multiplied by <math>(1.6 + rand(0.6))</math>.
*This means that the minimum and maximum requirement for Great Success for {{MapRoute|H|green}} is 25.6 and 35.2.
