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: (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's work without their consent/approval.

Several versions will be constructed through this page and will be reviewed and approved by the staff/collaboration committee before being moved for the Summer 2024 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.

Jiga's early Guide

Map Overview

E4 is a striking force, and combined fleet four-phase map, consisting of two transport and two boss phases.

3 LBAS are available to sortie on this map.
- After Phase 2, the LBAS is relocated closer to the final boss.

This map uses 2 locks:
- Operation Kon Fleet, Starting point 1 (striking),
- Operation Kon Reinforcement, Starting point 2 (combined).

This map is extremely hard to clear on all difficulties.
Please wait for information regarding compositions, historical bonuses, and friendly fleets across the event before starting it.
Especially in higher difficulties, advanced and exotic strategies are required and may not be available to most players.

Phase 1 - Eliminate the Enemy at Sorong (Boss)

Striking Force: 1 FBB, 1 CV, 0-1 CA(V)/CLT, 1 CL, 3-4 DD, Fast
Route: 1 A A2 C L

Striking Force: 2 FBB, 1 CVL, 1 CA(V)/CLT, 1 CL, 2 DD, Fast
Route: 1 A A2 C L

LoS check: Casual/Easy/Med/Hard = Cn3 34/45/60/50
LBAS range: 4
Bringing 1 or 2 OASW is recommended to clear the SS on LD.
The use of several Night Cut-ins is required to kill the boss.
Bringing AACI may help in the case the LBAS does not reliably clear the CVL.
Boss Support is recommended to help finish the boss off, especially on LD.

Phase 2 - Supply Transport to Sorong (TP)

Phase 2 is a "Transport Operation":

Striking Force: 1 CL, 4-6 DD, 0-1 AV
Route: 1 A A2 C M O P Q S

Striking Force: 1 CVL, 1 CA(V)/AV, 1 CL, 4 DD
Route: 1 A A2 C M O P Q S

Single: 1 FBB, 1 CVL, 0-1 CA(V), 1 CL, 2-3 DD
Route: 1 A A2 C M O P Q S
- This fleet has the advantage of being a single fleet and reusing more staged ships from the previous phase.

LoS check: ?
LBAS range: 6
Using the SFFCF SFFCF can help increase the reach rate.
Bringing ASW and AACI is recommended.
The pre-boss node contains several PT boats:

Anti-PT boat

Unlike most standard Abyssals, "PT boats" ( & ) 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]

The main Accuracy modifiers are

[math]\displaystyle{ \text{Mod}_\text{Amagiri} }[/math] being include in [math]\displaystyle{ \text{Acc}_\text{Atk} }[/math]:
- 65 for Amagiri Kai Ni/D
- 35? for DD and DE adjacent to Amagiri Kai Ni/D.
- 0 otherwise.
[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:
- Hidden accuracy bonus setups,
- Sparkled ships.

To secure the win condition for each difficulty, it's recommended that you run 2 FBB and 1-2 historical DD.
Bringing Node Support is recommended to ensure S rank, especially on Hard.
Using the SFFCF SFFCF can help increase the reach rate.
The event Vanguard Formation on the fleet will help pass through the previous nodes before reaching the targetted node.

Striking Force: 1-2 FBB, 0-1 CV, 1-2 CVL, 1 CL, 2-3 DD, Fast
Route: 1 A A2 B D F F1 G H

It's recommended to run 2 FBB and 1-2 historical DD to secure the win condition for each difficulty.
- It's also possible to send LBAS to F1 if the node is causing retreats.
Bringing Node Support is recommended to ensure S rank especially on Hard.
Using the SFFCF SFFCF can help increase the reach rate.
The event Vanguard Formation on the fleet will help pass through the previous nodes before reaching the targetted node.

Refer to #Phase 3 - Boss's fleet for composition and routing.
LBAS range: 3

Phase 3 - Destroy the Enemy Fleet at Biak

Note : This phase is incredibly hard and there is no known reliable way to defeat it.

The following recommended fleets require advanced gears and ships and require the use of as many historical ships as possible.
The use of Special Attacks is mandatory.
Using an STF is recommended over the CTF.
Doing the debuff is highly recommanded.

STF:
- Main: 2 (F)BB(V), 1 CV, 1 CAV, 1 CL, 1 AO/LHA
- Escort: 1 CA(V)/CLT, 1 CL, 4 DD

Longest route, but strongest fleet.
- Pass trough the Y ASS node.
This fleet can be slow, even when using both Yamato-class.
It is recommended to try to reach AS on the boss.
It is recommended to use an Underway Replenishment to reduce penalties.
- The AO/LHA should be either Kumano Maru Kai/Yamashio Maru Kai for fighter power, or Souya for Smokes.
The 1 CV + 1 CAV can be replaced with 2 CVL.
It is possible to replace the CAV with a BB(V) (notably for fighter mule), but this will pass through extra node T1

STF: Fast+
- Main: 4 (F)BB(V), 2 CVL
- Escort: 2 FBB, 1 CL, 2 DD, 1 SS
Route: 2 T T2 U U1 U2 V W Z

This fleet must be Fast+ when using both Yamato-class (see Speed).
- The SS must be a Sentaka Type to be able to reach F+.
This fleet should utilize a double touch, with a Kongou-class touch in the escort.

CTF: Fast(+)
- Main: 2 (F)BB(V), 3-4 CV, 0-1 CVL, 0-1 CAV
- Escort: 2 FBB, 1 CA(V), 1 CL, 2 DD

Shortest route
This fleet must be Fast+ when using both Yamato-class (see Speed).
- The SS must be a Sentaka Type to be able to reach F+.
- If the fleet is not Fast+, no Yamato-class can be included both an AS AND SS are needed to skip T1

STF: Fast(+)
- Main: 4 (F)BB(V), 1-2 CVL, 0-1 AS
- Escort: 1 CA(V), 1 CL, 3 DD, 1 SS
Route: 2 T T2 U U1 U2 V W Z
Shortest route
This fleet must be Fast+ when using both Yamato-class (see Speed).
- The SS must be a Sentaka Type to be able to reach F+.
- If the fleet is not Fast+, no Yamato-class can be included both an AS AND SS are needed to skip T1

LoS check: Casual/Easy/Medium/Hard = Cn3 90/85/95/100
LBAS range: 6

Bringing several OASW is recommended.
- Bringing an AACI is recommended if possible, but of a lesser significance if unavailable.
Using CV(L)/CAV/AO/LHA as fighter mules to reach AS on the boss is recommended.
Usage of both Node and Boss Support is needed to kill off smaller ships allowing your fleet to target bigger ships.

Node U is a night PT boats node, requiring anti-PT setups for escort fleet,
- The formation should be Vanguard.
