Sandbox Rules

This sandbox is to be used to construct an event guide for the above-mentioned event map. These guides are to all of the following requirements:

  • An overview of the map, including ship/equipment bonuses, Ship Locks, and special mechanics,
  • List of branching unlocking requirements (if there are multiple requirements, compositions for each path along with the below requirements will be needed to discuss the unlocking requirements in question),
  • A list of working compositions that work: (T=these must have possible alternatives for players who may or may not have all ships needed for a specific path),
    • The Paths said compositions will take (to explain each path the composition will/can take),
    • A summary or description of what kind of obstacles a composition will face.
  • A description of the boss node: what it consists of, and a descriptive guide on what the player should consider for a course of action to successfully win the battle,
  • Optional: Tips/guides to farm certain ships and/or resources (this can also require compositions, paths, and possible descriptions).

Editors are to construct their own version of the guide/part of the guide, and complete it in a timely fashion.

No editor is allowed to edit over other editors' work without the consent of the editor and his approval to do so.

Several versions will be constructed through this page and will be reviewed and approved by the staff/collaboration committee before being moved for the Spring 2025 Event, being reviewed and updated once more before it can be released.

Overall there should be 3 versions of the guide that have to be constructed, including: Preliminary > Polished > Finalized Guides

With each approval of each version of the guide, the said guide will be updated to the main page, and construction of the next version will begin.

All guides outside of the approved version will be removed and work will begin from the approved version to make it better for the next version until the finalized version is made.

Map Overview

E3 is a single and combined fleet, three-phase map consisting of three boss phases.

  • 3 LBAS are available on this map:
    • Only 2 can be set on Sortie, the other being limited to Defense,
  • This map uses 3 locks:
    • Spring 2025 Event Tag 1.png 104th Squadron, Starting point 1 (reused from E-1)
    • Spring 2025 Event Tag 3.png 5th Fleet, Starting point 2 (reused from E-2)
    • Spring 2025 Event Tag 4.png Combined Fleet, Starting point 3

The use of Aviation PersonnelAGDP AGDPArctic Gear & Deck Personnel on CV(B/L), Ise-class Kai Ni, Akitsu Maru Kai, Kumano Maru, and Yamashio Maru, is required to sortie these ships on the map.

Fleet Notes
The enemy is a surface fleet.
  • PT Imp Packs and submarines are on the route, it is therefore advised to bring some ASW and anti-PT setups:
Anti-PT boat
Unlike most standard Abyssals, "PT boats" (PT Imp PackPT Imp Pack & Schnellboot Imp PackSchnellboot Imp Pack) are "very small and fast".
  • All ship types suffer a severe Accuracy accuracy and Firepower 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.

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.

A stronger fleet that cal allow 2 FBB, but that route through extra node F3 witch contains a sub loli.
  • The Fleet only needs to be fast when using 2 FBB, else, it can be slow.
  • Bringing ASW is recommended.
  • Bringing an AACI is recommended.
LBAS Notes
All bases should be sent on the boss.

To route E F, the Medium ArmorMedium Arctic Camouflage (+ Arctic Equipment)Arctic Camouflage (+ Arctic Equipment) must be equipped in the fleet:

  • On 3+ ships in hard,
  • On 1+ ships in medium,
  • On 0+ ships in easy/casual.

Otherwise, the fleet with pass through extra node E2

Using Boss support is recommended.

PT Imp Packs are on the route, it is therefore advised to bring some anti-PT setups:

Anti-PT boat
Unlike most standard Abyssals, "PT boats" (PT Imp PackPT Imp Pack & Schnellboot Imp PackSchnellboot Imp Pack) are "very small and fast".
  • All ship types suffer a severe Accuracy accuracy and Firepower 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].

  • Be advised that if a land base is sent to R, planes and rank loss will be significantly higher.
    • It is therefore recommended to bring several Barrage Balloon Barrage Balloons in order to both mitigate these and buff allied aircraft damage.

As only the non-installation flagship needs to be killed, it is highly advised to use as much TCI as possible in the escort fleet, in order to focus on the surface ships and ignore the installation during the torpedo phases and night battle.

  • Using Boss support is recommended.

The node has several Installations, notably a Supply Depot Princess D.

It also has of a Transport Ship Wa-Class B (Landing) Elite, which has high AA strength and is armed with a Barrage Balloon Barrage Balloon, to counter damage from carriers and LBAS.

  • Be advised that if a land base is sent to R, planes and rank loss will be significantly higher.
    • It is therefore recommended to bring several Barrage Balloon Barrage Balloons in order to both mitigate these and buff allied aircraft damage.

PT Imp Packs are on the node, it is therefore advised to bring some anti-PT setups:

Anti-PT boat
Unlike most standard Abyssals, "PT boats" (PT Imp PackPT Imp Pack & Schnellboot Imp PackSchnellboot Imp Pack) are "very small and fast".
  • All ship types suffer a severe Accuracy accuracy and Firepower 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].

    • 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.

  • 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 Amphibious Vehicle Ka-Tsu TanksSpecial Type 4 Amphibious Tank
    Special Type 4 Amphibious Tank Kai     bonus does not stack with the Landing Craft Armed BoatsSoukoutei (Armored Boat Class)
