Tips

Be advised: The Developers have mentioned that the composition and map will change over time, this may even include the resource node. So take advantage of the map while it is possible.

This map only has a single phase, however, 2 main routes are present:

• The main boss route, ending at node P,
• The resource route, ending at node O.

In addition, one LBAS can be unlocked and its use it highly advised.

• It is unlocked by quest B175.

This map notably features a lot of submarines, and so requires adequate ASW capabilities to be defeated.

Formation Notes

It is advised to use the following Formations:

• Line Abreast on nodes B C G J K L
• Diamond on nodes E M
• For Boss P, depending on how the LBAS is setuped:
  • Line ahead is recommended if the LBAS can effectively kill the enemy SS.
  • Echelon is preferred if the LBAS is not set to fight SS.

Regarding Land-Based Air Squadrons

• 1 LBAS is available to sortie.
• It is highly recommended to use the LBAS to either help reaching or defeating the boss node.
• This map is also the best location to train all land-based planes to max-proficiency ❱❱ . Bring only planes with a range of at least 3 (7 for furthest nodes) as they will reach submarine Nodes on B, C, J, and K.

Recommended Fleets

Reach Node O

Quest B175 requires to reach node O:

Fleet Notes
Several Seaplanes or Submarine Radars might be needed to have enough LoS to route from M to O. Submarines will face little to no threat along the way.

Sink the Hi Convoy Princess

In this part, it is recommended to use the LBAS to clear the map more easily, as this will give the necessary edge needed to fight against the boss. While the boss is not strong, she is very tanky and is escorted by a fleet that may be troublesome to wipe.

Fleet Notes
Allows bringing a strong fleet to the boss, passing through 2 Submarine Nodes, 1 Air Node, and 2 Surface/Submarine Nodes. Node J can especially be problematic due to it featuring 3 Submarine So-Class Flagship, but will become even more dangerous on Last Dance with the enemy fleet in line ahead formation. It is recommended to bring: Ships that can effectively OASW to kill the numerous submarines. An Ise-class Kai Ni and a CVE to help clearing while having AS. An AACI for node E as well as the boss. At least 1 TCI capable DD. If possible, ships that can take on multiple roles. The boss does not have a lot of planes, bringing enough airpower and AACI can effectively deplane her, rendering her defenseless. Last Dance comp will buff the DD and CL in her fleet along with giving her additional airpower. Bring additional airpower as a countermeasure to effectively beat her.
LBAS Notes
It is recommended to bring 1-2 Land-Based Attackers, 1-2 land-based ASW bombers , and 1-2 fighters, to increase effectiveness at the Boss.

ExpandTorpedo Squadron

Fleet Notes
This solution requires more advanced gears, and might be out of reach of new players. It is required to bring an FCF capable CL as flagship, preferably an Agano-class Kai+, equipped with: 2 Main Guns, 1 Prototype Night Zuiun (Attack Equipment), Do note that the Night Zuiun will likely be shot down completely due to fighting under AI and the presence of CL Tsu-Class. And the ETSCF Elite Torpedo Squadron Command Facility (preferably in the RE). It also requires at least 5 OASW along with married DDs to allow them to do TCI while enabling their OASW with sonar alone. If all of the above requirements are met, this is the cheapest (for resource) and the best comp for farming the boss node, having the highest pass rate thanks to the usage of ETSCF in case a ship gets heavily damaged. The evacuation mechanic of the ETSCF should be used if needed, as long as the routing is maintained. C E routing is maintained as long as the 4 DD are left. The boss routing is maintained as long as the fleet keeps enough LoS'.
LBAS Notes
It is recommended to bring 1-2 Land-Based Attackers, 1-2 land-based ASW bombers , and 1-2 fighters, to increase effectiveness at the Boss.

ExpandSuper Light Fleet

Fleet Notes
Completely gives up S rank as it is almost impossible to kill the boss, but can be useful if only an A rank is required (DE still drop in A rank, albeit at a lesser rate) while leveling DE on the way. It is a cheap but weak fleet, utilizing this map's special routing for Taiyou-class and CT, who can be brought when using light fleet to get more firepower. Goes through, 1 Submarine Node, 1 Air Node, and 1 Surface/Submarine Node. Nodes E and P may be troublesome due to a lack of air defense. Dependent on the only DD or CVE to score the kill against the boss, with DE taking on OASW. The DD should do a TCI, and CVE do a night carrier cut-in in order to sink the boss. Hatsuzuki Kai Ni and Inagi Kai Ni are also among the best picks, stabilizing the route to the boss thanks to Hatsuzuki's AACI and OASW along with Inagi's higher stats compared to the other DEs.
LBAS Notes
Should focus on removing the surface ships to make scoring the kill against the Boss more likely.

This map can be farmed to obtain:

• Fuel and bauxite ,

Fleet Notes
It is possible to farm both fuel and bauxite by reaching node O. Doing this farming will bring 2 losses per run on the submarine nodes C K, which can impact overall win rate and thus "event eligibility". This issue is fully mitigated by using the ASW seaplane strat. A maximum of Amphibious Vehicles should be used as they provide the best earnings for submarines. Drum Canister-capable SS are recommended as a substitute, increasing the resource gains without requiring more Amphibious Vehicles. The gain cap being relatively low, it will be capped by using only 10 or 4 + 8 . It is not possible to reach the gain cap with a submarine only fleet. To meet the LoS requirement, using Seaplanes and/or Submarine Radars may be required. If possible, it can be advisable to use RE, as Submarine Radars can fit in them. While this map has little to no threat against a full submarine fleet, J will have rare instances where destroyers may pop up in the composition that will damage the SS. Please be aware of this while farming this map. Refreshing the game each time this comp shows up in the fleet preview will fully prevent this issue. Do not consider farming during Boss Last Dance, as J will be locked on this 2 Destroyer composition.
LBAS Notes
Sending a single Recon ASW Seaplane Recon LBAS on each submarine node will mitigate this issue cheaply.

Fleet Notes
This fleet should be preferably the above mentioned resource route, in order to kill 2 birds with 1 stone.
LBAS Notes
It is possible to farm for LBAS Plane Proficiency ❱❱ by sending the LBAS on a submarine node like J or K. Just set-up an LBAS with any planes, according the final range is enough to reach J or K. Sending a surface-focused LBAS on J can assure a safer path. Such runs consume little to no resources on the LBAS.
