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

E3 is a single, 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
- Initially, no LBAS is available,
- After Phase 1, all can be set on Sortie.

This map uses 2 locks:
- Home Fleet, Starting point 2 (reused from E-1),
- Force M Advance Squadron, Starting point 1 & 3 (single),
- Force M, Starting point 1 & 3 (combined).
Note : It is possible to mix both & in all difficulties on the last phase ONLY once the shortcut gimmick cleared.

Barrage Balloons can be deployed on installation nodes V1 X.

Phase 0.5 - Gimmick

To unlock the second boss, the following steps have to be performed:

	B2	C2
Hard	S x2	AS x2
Medium	S x2	AS
Easy	S x2	AS
Casual	S	AS

Single Fleet: 0-2 (F)BB(V), 3 CV, 1-3 DD
Route: 1 A B B2

Refer to #Phase 1 - TP's fleet for composition and routing.

	AS
Hard	378
Medium	378
Easy	225
Casual	201

Phase 1 - Boss

Single Fleet: 1-2 (F)BB(V), 1-2 CV, 3 DD
Route: 1 A B C C2 C3 F
Shortest route to the boss.

Single Fleet: 1-2 (F)BB(V), 1-2 CV, 1 CVL, 2 DD
Route: 1 A B B1 C C2 C3 F
Allows an additional CVL, but, passes through extra node B1.

LoS check: Cn3 = H/M/E/C = 80/60/60/?
Bringing ASW and AACI is recommended.
In the case 2 (F)BB are used, it is recommended to use a 2 ship Special Attack.
- This would eventually be reused on the final phase.
CV can utilize CVNCI do deal nigh damage.

Phase 2 - TP

Phase 2 is a "Transport Operation":

Striking Force: 0-1 CV/CA(V), 1 CL, 4-5 DD, 0-1 AV, Fast
Route: 2 H H2 I K
LoS check: Cn3 = H/M/E/C 65/55/50/?
Slow fleets pass through node H1.
Using a Support Fleet on the boss is recommended guarantee an A+ rank at the boss node.
Bringing ASW is recomanded.
LBAS Range to K is 1.

Phase 3 - TP

Phase 3 is a "Transport Operation":

TCF:
- Main: 1 CVL, 1-4 DD, 0-3 DE, 1 AV
- Escort: 0-1 CA(V), 1-2 CL, 4 DD
Route: 1 L M B1 P Q S
It is recommended to send the full LBAS on the boss.

CTF:
- Main: 1 CV, 1 CVL, 1 LHA, 1 CL, 2 DD
- Escort: 2 FBB, 1 CL, 3 DD
Route: 1 L M B1 P Q S
This comp is stronger and is only recommended when struggling to reach the boss or to S rank the boss.
Use of Smokescreen can help with pass rate on P Node
This comp is costlier on ships to lock.

STF:
- Main: 2 FBB, 1-2 CAV, 2-3DD
- Escort: 0-1CAV, 1 CL, 4-5 DD
Route: 1 L M B1 N O P Q S
This comp is stronger and more survivable against S-Boats on P Node. Same with CTF, is only recommended when struggling to reach the boss or to S rank the boss.
Use of Smokescreen can help with pass rate on P Node
This comp is costlier on ships to lock.

LoS check: 90 (Cn3 Hard)
LBAS range: 7

Phase 3.5 - Shortcut

Once phase 3 is cleared and phase 4 unlocked, the following steps have to be performed to unlock a shortcut, and allow to bring mix tags.

This gimmick is optional but highly recommended.

	S	V1	V3
Hard	S	A+ x3	S
Medium	S	A+ x3	S
Easy	A+	A+ x2	S
Casual	A+	A+ x2	S

Refer to #Phase 3 - TP's fleet for composition and routing.

CTF:
- Main: 2 FBB, 2 CV, 1 CVL, 1 DD, 1 AV/LHA
- Escort: 0-1 CA(V)/LHA, 1 CL, 4-5 DD
Route: 3 P U V V1
1 LHA is required to reach the node.
The node contains several installations and 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]
Type	Luck	Eva	Line Ahead	Echelon	Line Abreast
PT Imp Pack	?	?	81?	87?	?
PT Imp Pack II	60	220	80	87	85
PT Imp Pack III	60	250	82	89	88

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]:
- 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].

Ship Type	[math]\displaystyle{ \text{Mod}_\text{Ship} }[/math]

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.
