Tips

Be advised: The Developers have mentioned that the enemy compositions and map may change over time [3]. So take advantage of the map while it is possible.

The 1st normal map to feature 3 phases as well as a gimmick.

  • The 1st and 3rd phases are standard surface battles.
  • The 2nd phase is installation focused, featuring PT boats.
  • A "gimmick phase" is required to unlock the last phase.

A lot of branchings are active ones, making the overall routing easier.

In every phase:

  • Bringing AACI is recommended.
  • Bringing OASW is advised if not too detrimental to surface combat effectiveness.
  • Bringing historical ships is recommended.

  • Max of 2 (F)BB(V)+CA(V)

There is no air power on the boss node.

Gimmick Phase

In addition to clearing Phase 2, Node M must be S ranked to unlock Phase 3. This step can be done at any point, right after clearing Phase 1. As it can use the same fleet as Phase 1, it is more convenient to do it after clearing Phase 1.

Fleet Notes
Shortest route to the boss.

The boss is an "Installation" and requires appropriate gears to be defeated,

  • The boss fleet includes one or two PT Imp Packs, requiring appropriate gears to be defeated (these can be ignored if an S-rank is unnecessary):
Anti-PT boat
Unlike most standard Abyssals, "PT boats" (PT Imp Pack  & Schnellboot Imp Pack ) are "very small and fast".
  • All ship types suffer a severe   accuracy and   firepower penalty against PT boats.
  • Attacking them with larger guns is not very effective, smaller guns being recommended instead.
  • Support Expeditions are not affect by any of the following[1].
Attack formula against PT boats
The Attack formula against PT boats:[2][3]
Jet Assault & Airstrike
  • [math]\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.5 ; 0.8] }[/math]


LBAS[4]
  • [math]\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.4 ; 0.7] }[/math]


Shelling
  • [math]\displaystyle{ \text{Damage}_\text{PT}= ( 0.3 \times \text{Atk}_\text{post-cap} + \sqrt{\text{Atk}_\text{post-cap}} + 10 ) \times \prod^{All Equipment}{\text{Mod}_\text{EquipmentAtk}} }[/math]


Opening & Closing Torpedo Salvos
  • [math]\displaystyle{ \text{Damage}_\text{PT}= 0.3 \times \text{Atk}_\text{post-cap} + \sqrt{\text{Atk}_\text{post-cap}} + 10 }[/math]


Night Battle
  • Night Battle data are unclear yet.


With
  • [math]\displaystyle{ \text{Atk}_\text{post-cap} }[/math] the post cap attack power defined here,
  • [math]\displaystyle{ \text{Mod}_\text{EquipmentAtk} }[/math] the bonuses given by equipment, described below.
Accuracy formula against PT boats
The Accuracy formula against PT boats:[5][6][7][8]
[math]\displaystyle{ \text{Hit Rate}_\text{vs.PT} \text{%} = \Big\lfloor ( 0.3 \times \text{Accuracy}_\text{Atk} + \sqrt{\text{Accuracy}_\text{Atk}} + 15 ) \times 1.2 \times \text{Mod}_\text{Ship} \times \Big( \prod^{All Equipment}{\text{Mod}_\text{EquipmentAcc}} \Big) \times \text{Mod}_\text{Night} \Big\rfloor - \text{EVA}_\text{PT} + 1 }[/math]
With
  • [math]\displaystyle{ \text{Acc}_\text{Atk} }[/math] the standard accuracy described here
    • PT boats are "DDs" in the game, so the [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] for vanguard is 1.1 during shelling, and 1.2 during the torpedo phase.
    • Historical accuracy bonuses during Events are included in the Standard Accuracy Term, i.e. it is affected by the [math]\displaystyle{ \text{Mod}_\text{PT} }[/math] modifier.
  • [math]\displaystyle{ \text{EVA}_\text{PT} }[/math] the PT estimated evasion   described bellow,
PT boats stats
Type Luck   Eva   [math]\displaystyle{ \text{EVA}_\text{PT} }[/math]

PT Imp Pack IV  ? ? ? 84? ?
Schnellboot Imp Pack  ? ? ? ? ?
Schnellboot Imp Pack II  ? ? ? ? ?
Schnellboot Imp Pack Elite  ? ? ? ? ?


The main Accuracy modifiers are
  • [math]\displaystyle{ \text{Mod}_\text{Amagiri} }[/math] being include in [math]\displaystyle{ \text{Acc}_\text{Atk} }[/math]:
  • [math]\displaystyle{ \text{Mod}_\text{Ship} }[/math] the bonus given by ship types, described below,
  • [math]\displaystyle{ \text{Mod}_\text{EquipmentAcc} }[/math] the bonuses given by equipment, described below,
  • [math]\displaystyle{ \text{Mod}_\text{Night} }[/math] being 0.7 during night battle, 1 during day battle.


Amagiri Kai Ni/D 
  has the ability to prioritize focusing on attacking PT imps with significantly increased accuracy if any are present.

  • DD placed in the composition slots above and below her will gain a noticeable accuracy boost and will prioritize attacking PT boats if any are present.
  • The PT boat targeting rate is 100% for all affected ships [9].

During Events, some special bonuses may be added, with "historical" ships and equipment gaining some accuracy bonuses[10].

Notes
  • It is recommended to use anti-PT setups on DDs only, such setups compromising overall combat effectiveness.
  • Having a Reinforcement Expansion is important because it can save a ship slot by containing a machine gun or skilled lookouts.
  • Combining equipment is recommended to see significant boosts to accuracy.
  • The   Ka-Tsu Tanks 
          bonus does not stack with the   Armed Boats 
          ones.
  • Using other setups improving accuracy is also advisable:

Phase 3

The final boss has very high armor, so using historical ships and Night Cut-ins is required to reliably defeat it.

SS and Carrier Exp farming

The 1st enemy node being an Air Node, it's possible to take advantage of how it works to level up any SS(V) as well as "carriers" risk-free.

  • All SS(V) won't take any damage on Node A, so any SS(V) fleet can level up risk-free on this node.
  • If possessing one or more 12cm 30-tube Rocket Launcher Kai Ni , it is possible to take advantage of the AARB mechanic to also level up BBV, CV(B/L), CAV, and AV.
    • By equipping one RLK2 on carriers, passing a certain AA threshold, said carrier won't take any damage on the Air Node.
    • Having more than 1 RLK2 on the same ship decreases the AA threshold, making it possible to level up weaker carriers.
  • Once Node A cleared , retreat to the base and repeat.
