===Tips===
====Regarding [[Land-Based Air Squadron]]s====
See the unlocking steps here: ''[[Land-Based_Air_Squadron#Unlocking|LBAS Unlocking]] ''
*You are permitted to use 1 [[LBAS]].
*Upon completing the quest [[Quests#B175|B175]], you will gain access to an LBAS, which is '''highly recommended''' to help simplify the battle on the boss node for this map.
*It's recommended to bring Land-Based Bombers, Fighters, and ASW planes in it if you want to increase your effectiveness on the Boss.
*The LBAS range needed to reach the boss is '''2''', and the other nodes range is equal or higher.
**Bring planes with a distance of 2 or more in order for this to support an attack on the boss node.
*This map can also serve as a good location to train your Land-Based attack planes to max expertise. Bring only Land-Based Attackers with a distance of 3 or 7 (or more) as they will reach enough distance to reach submarine Nodes on B, C, J, and K, where your planes should target in order to be trained.


===Recommended Fleets===
This guide will go over the events of this map from the sequential order after you unlock Quest [[Quests#B175|B175]]. Since this is a normal map, you do not necessarily have to complete things in the order mentioned, but to make things most convenient for you, it's recommended to at least complete B175 to access the LBAS.

==== Traveling to Kaohsiung (For Quest [[Quests#B175|B175]])====
The goal is to reach node {{MapRoute|O|green}} and not the boss.
* 1-6SS(V)
* Route = {{MapRoute|C|red|D|pink|F|blue|J|red|K|red|M|pink|O|green}}
* The LoS Range needed is estimated to be 32 (Cn3).
* Submarines will face little to no threats along the way. At most, they will take 2 losses and 3 wins.
* You might need several [[List of Seaplanes by stats|Seaplanes]] or {{EquipmentLink|Submarine Radar & Waterproof Telescope|Submarine Radar & Passive Radiolocator (E27)|Late Model Submarine Radar & Passive Radiolocator|text=Submarine Radars}} to have enough LoS and so route from {{MapRoute|M|pink}} to {{MapRoute|O|green}}.
* Once your submarine fleet reaches {{MapRoute|O|green}} you will gain {{Fuel}} and {{Bauxite}}.
** For more information please review the farming guide further below.

====Sink the Hi Convoy Princess====
In this sequence, it's recommended to have opened the LBAS beforehand to make this section of the map easier as the assistance of an LBAS will help give you the necessary edge needed to fight against the boss in this map. While the boss is not strong, the fleet she is accompanied with may present issues if you cannot wipe it. 

Below is a guide on the recommended compositions that will work effectively against the boss on Node {{MapRoute|P|red}}.

<tabber>
|-|Heavy fleet =
*0-1BBV, 1CVL, 1CA/CL, 2-3 DD, 1-2 DE
*Route = {{MapRoute|A|blue|B|red|E|pink|J|red|L|red|P|red}}
LBAS Node {{MapRoute|P|red}}: Range = 2

* Will allow you to bring a very strong fleet to the boss.
* Fleet will need a group of ships that can effectively [[OASW]] to survive the dangerous submarines on this map.
* [[Hyuuga Kai Ni]] and a CVE is recommended to help make clearing more possible.
* Fleet will have to go through 2 Submarine fights, 1 Air Node, and 2 Surface/Submarine fights.
* Node {{MapRoute|J|red}} can especially be problematic due to it featuring 3 [[Submarine So-Class|So-class flagship]] submarines, but will become even more dangerous on Last Dance due to the fact that the enemy fleet will be in ''line ahead'' formation.
* [[AACI]] is also recommended for node {{MapRoute|E|pink}}
* At least 1 TCI DD is recommended.
* If possible bring ships that can take on multiple roles to effectively clear the map easily.
* The boss does not have a lot of planes, bringing enough airpower and AACI can effectively deplane her, rendering her defenseless.
* LBAS should use a combination of Fighter, Bombers, and ASW Bombers to effectively help with clearing the boss.
* Last Dance comp will buff the DDs and CL in her fleet along with giving her additional airpower.
** Bring additional airpower as a countermeasure to effectively beat her.

|-|Light fleet=
*1CT, 1DD, 3DE
*Route = {{MapRoute|A|blue|B|red|E|pink|J|red|P|red}}
*LBAS Node {{MapRoute|P|red}}: Range = 2

* Will go through, 1 Submarine fight, 1 Air Node, and 1 Surface/Submarine fight before reaching the boss.
* Not recommended entirely due to the risks this map may present to your fleet due to lack of strong combat-effective ships.
** You will be depending specifically on one DD to score the kill against the boss.
** DEs will mainly take on OASW.
** The CT will mainly do Surface Combat.
** The DD will do the TCI.
* Node {{MapRoute|E|pink}} and {{MapRoute|P|red}} may present issues on your chances of passing due to lack of air defense.
* LBAS should focus on removing the surface ships to make scoring the kill against the Princess more likely.
** Your DD will need to avoid taking too much damage to effectively kill the boss.
* '''Not recommended for Last Dance'''

|-|Formation Guide=
See: ''[[Combat#Formation_Selection|Formations]]''.<br>

It is advised to use ''Line Abreast'' on most of the map :
* Nodes {{MapRoute|B|red|C|red|G|red|J|red|K|red}}
''Diamond'' is advised on :
* Nodes {{MapRoute|E|pink|M|pink}}
For Boss {{MapRoute|P|red}}:
* Depending on how you set up your LBAS :
** '''Line ahead''' is recommended if your LBAS can effectively take out the enemy SS.
** '''Double Line''' is preferred if your LBAS is not set to fight SS.
</tabber>

===Resources and LBAS Farming===

* 1-6SS(V)
* Route = {{MapRoute|C|red|D|pink|F|blue|J|red|K|red|M|pink|O|green}}
** LoS required: '''≥ 32''' (Cn3)

It is possible to farm both Fuel {{Fuel}} and Bauxite {{Bauxite}} by reaching node {{MapRoute|O|green}} using all submarines.
* Base amount of resources are 40 fuel and 20 bauxites without the uses of DLC or Drum.
* Each {{EquipmentLink|Special Type 2 Amphibious Tank|text=Tank}} provides + 7 Fuel {{Fuel}} and + 10 Bauxite {{Bauxite}}
* Each {{EquipmentLink|Drum Canister (Transport Use)|text=Drum Canister}} provides + 8 Fuel {{Fuel}} and + 6 Bauxite {{Bauxite}}
** Only work for [[Luigi Torelli]].
* The maximum gain you can earn is '''120''' of each resource.
* It is possible to farm for LBAS [[Plane Proficiency]] by sending your LBAS on one of the submarine nodes like {{MapRoute|J|red}} or {{MapRoute|K|red}}.
* While this map has little to no threats against submarines, {{MapRoute|J|Red}} will have rare instances where destroyers may pop up in the composition that will damage your SS. Please be aware of this while farming this map.
* Do not consider farming during Boss Last Dance, as {{MapRoute|J|Red}} will be locked on the 2 Destroyer comp that will pose a threat to your SS.
**Sending a surface-focused LBAS on {{MapRoute|J|Red}} can assure you a safe path no matter the enemy comp. Such runs consume little to no resources on your LBAS.
{{color|red|Doing this farming will bring you a lot of "loses", which can impact your overall win rate and so your "event eligibility".}}



{{color|orange|Be advised: The Developers have mentioned that the composition and map will change over time, this may even include the resource node possibly. So take advantage of the map while you can.}}
