=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 [[{{ROOTPAGENAME}}]], 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.

=XX's Guide=
==Map Overview==
E4 is a Combined fleet four-phase map consisting of one transport phase and three boss phases.
* 3 [[LBAS]] are available to sortie on this map.

* This map uses 4 locks:
** [[File:{{ROOTPAGENAME}} Tag 8.png|40px]] '''3rd Fleet''',
** [[File:{{ROOTPAGENAME}} Tag 9.png|40px]] '''Wake Island Transport Unit''',
** [[File:{{ROOTPAGENAME}} Tag 10.png|40px]] '''The New Tatsumaki Fleet	''',
** [[File:{{ROOTPAGENAME}} Tag 11.png|40px]] '''Op. Z Decisive Battle Fleet'''.

*An '''[[Emergency Anchorage Repair]] node''' is present on {{MapRoute|W|lightblue}},
*An '''[[Node|"Airstrike Supported Battle" node]]''' is present on {{MapRoute|K|darkorange}},
*Node {{MapRoute|S|Red}} is an "atoll node", where the new {{Amphibious Tank}} {{Equipment/Link|Special Type 4 Amphibious Tank|Special Type 4 Amphibious Tank Kai|text=Ka-Tsu tanks}}' opening can be deployed.

* CTF/STF: '''2 (F)BB(V), 2-3 CV(B/L), 1-2 CAV/CL/DD + 0-2 CA(V)/CLT, 1 CL, 3-5 DD, Fast ''' [[File:{{ROOTPAGENAME}} Tag 8.png|40px]]
* Route: {{MapRoute|1||A1|red|B|blue|C|red|C1|pink|E|red|F1|pink|G|red}}
**This is the most advised fleet, as it brings the best balance of power.
**4 DD are needed when using both {{Class|Yamato}}

|-|Slow=
* CTF: '''2 (F)BB(V), 2 CV(B/L), 2 CA(V)/AV, 1 CL/DD + 0-1 CA(V), 1 CL, 3-5 DD, Slow''' [[File:{{ROOTPAGENAME}} Tag 8.png|40px]]
* Route: {{MapRoute|1||A|red|B|blue|C|red|C1|pink|E|red|F1|pink|G|red}}
**Equivalent to the fast fleet, being more permisive for slow ships, but with one less carrier.

**This fleet brings the highest air power, helping reaching AS on the boss.
**This fleet is not recommended, as it lacks a special attack and will struggle damaging the bosses
</tabber>

*LoS check: ??
* LBAS range: 5
* AP/AS:
**307/690 (Hard pre-LD)
**449/1008 (Hard LD)
*Bringing an [[AACI]] and several [[OASW]] is recommended.
*All LBAS should be sent to the boss, with 2 fighters and 2 bombers per base.
*Using both an ASW node support expedition and a boss support expedition is recommended.
*The use of [[Special Attacks]] is recommended, especially the [[Yamato]] touch, as this can be a fast fleet touch.
*Using {{Smoke}} [[Smoke]]s can help pass through node {{MapRoute|C|red}} a bit in some cases.

==Phase 2: TP==
Phase 1 is a '''"[[Transport Operation]]"'''.

* TCF: '''1-2 AV, 0-1 [[CVE]]/CL, 4-5 DD + 1-2 CL, 4-5 DD''' [[File:{{ROOTPAGENAME}} Tag 9.png|40px]]
* Route: {{MapRoute|2||H|blue|J|pink|J1|red|J2|red|M|green|O|red}}
*LoS check: ?
*LBAS range: 9

*As many {{Landing Craft}} [[Landing Craft]], {{Drum}} [[Drum Canister]]s, and {{Amphibious Tank}} [[Amphibious Tank]]s should be utilised in the fleet.
*Bringing an [[AACI]] and several [[OASW]] is recomanded.

==Phase 3: Boss 3==
The boss node is an "atoll node", meaning that it is possible to deploy the new {{Amphibious Tank}} {{Equipment/Link|Special Type 4 Amphibious Tank|Special Type 4 Amphibious Tank Kai|text=Ka-Tsu tanks|link=Ka-Tsu}}' opening.
*The new [[Atoll Aircraft Carrier Anchorage Princess]] is not an "[[Installation]]".

<tabber>
|-|AS Fleet=
* Striking Force: '''1 AS, 4-5 SS(V), 0-1 AV, 1-2 DD''' [[File:{{ROOTPAGENAME}} Tag 10.png|40px]]
* Route: {{MapRoute|1||P|pink|J|pink|J1|red|R|red|S|red}}
* This fleet can utilize the "Submarine Touch", a {{Submarine Touch}}

|-|No-AS Fleet=
* Striking Force: '''4 SS(V), 1 CAV, 1 CL, 1 AV''' [[File:{{ROOTPAGENAME}} Tag 10.png|40px]]
* Route: {{MapRoute|1||P|pink|J|pink|J1|red|R|red|S|red}}

</tabber>
* LBAS range: 9
* Having an [[AACI]] is recomanded.
*[[PT boat]]s are present in the boss comp:
{{Anti-PT Imp Setups}}
Using the Ka-Tsu tanks attacks is mandatory in higher difficulties:

{{:Ka-Tsu}}
When using it, it is better to have pairs of Ka-Tsu on the historical ships, and normal [[Night Cut-in]]s for the other ones.

==Phase 4: Boss 4==

* STF: '''1BBV, 0-1 CAV, 3-5 CL, 0-1 DD/DE + 1 CL, 3-5 DD, 0-2 DE''' [[File:{{ROOTPAGENAME}} Tag 11.png|40px]]
* Route: {{MapRoute|3||T|red|U|pink|V|red|X|pink|Z|red}}
**LoS check: ??
**LBAS range: 10
*As the flagship boss is a submarine, it possible and heavily advised to focus the fleet on OASW and snipe the boss.
*As many [[OASW]] as possible ships should be utilized in the escort fleet
*The main fleet should maintain high [[ASW]], with additional roles such as:
**One [[AACI]] ship,
**{{IconText|{{CommandFacility}}|FCF}} {{Equipment/Link|Fleet Command Facility|text=FCF}} on the flagship,
**{{SPF}}/{{Fighter}} on the BBV/CAV/CL for air power
**{{Smoke}} [[Smoke]]s for better on route survability.
**LoS ships for routing.
*The [[LBAS]] can be either:
**ASW focused to kill the boss,
**Surface focused to clear the boss escort or the pre-boss nodes.
*As it is a combined fleet, it is possible to kill the submarine boss even on night battle.

==Phase 4.5: Debuff==
Once LD has been reached, the following steps have to be performed to debuff the boss.
*Debuff might be optional for most players, as the boss ASW snipe is generally enough to kill the boss.
