When the difficulty is changed, the boss's health bar will be reset.
Once the map is cleared (boss HP bar is depleted and killed), you CANNOT go back and change the difficulty.
The First Class Medal symbol (the one that appears beside your name in your Admiral page) is given, along with the medal item (the one in your inventory) the moment you clear E-5 on hard, regardless of the difficulties chosen for previous maps.
There is no ship locking for this event.
The boss HP gauges does not regenerate over time in any map in any difficulty.
Support Expeditions are available. Expedition 141 Focuses on Support for Normal Nodes, Whereas Expedition 142 Focuses Support on Boss Nodes. The Expeditions DO REQUIRE that you have 2 DDs in your fleet. Do take note that their expeditions will end early after you finish one sortie, so try to make the most use out of them.
The Chocolate is exchangeable for some resources. You should keep it because it's cute. (700 fuel 700 steel 700 ammo 1500 bauxite on used.) BE WARY WHEN CLICKING ON THE CHOCOLATE, THERE IS NO CONFIRMATION SCREEN AND IT WILL BE AUTOMATICALLY CONSUMED WHEN CLICKED
Admirals can farm for Akashi in E-1, even if they already own one or more.
Random between A and B
More than 1 CL or insufficient LOS will send you from H to G
LOS check from G to I
LOS check from H to I (Apparently requires more LOS than G to I)
LOS must be 120 or higher to avoid going from H to J (On easy difficulties, still need more data)
LOS requirement is 90 and above. Lower than that will send you to Node J if you're from Node H and Node K if you're from Node G (Tested and confirmed on Easy and Medium Difficulty).LOS is affected by HQ level. This number is useless without a HQ level as a reference.
Recommended ELOS (new formula) of 50 or more. (Needs confirmation, seems much too high)
Have some surface equip ready for Node G as there will be surface opponents.
All other nodes are pure submarines.
Fighting Sub-only nodes does not expend ammo
The submarines on node H are in line ahead formation. Use line abreast when attacking them.
Type 0 Recon Airplane is very useful for increasing LOS for node I
The boss BGM is 『吹雪』, the ending theme of the anime.
A fleet without DD/CL/CVL/Akitsumaru/Akashi will always end up at the dead end J
At least 2 DD/CL/CVL/Akitsumaru/Akashi OR 1 CV + 1 CVL(any combination) and not more than 1 CLT required to start with node A
2 BBVs will send you to the maelstrom node
1 CL, at least 3 DD, fast fleet, and and not more than two of (CL, CLT, CA (not CAV), BB, CV, empty slot) required to go from A to D, otherwise you go to F.
A fleet with at most 1 BB and at most 1 CV goes from F to G, otherwise it's H
CL + CAV + CV + 3xDD goes A->D->E->G->I (Boss)
LOS check from G/H to I
If you're having trouble getting to the boss, it's advisable to avoid starting at node B; fuel loss = higher chances to get hit
E-2 Boss Final Kill Air-Power:

CLT can be taken, without 2CVL bound to going to maelstrom node
Node B is a fuel maelstrom and Node D is "no battle"
Akizuki (Kai), Fubuki (Kai Ni), Hatsushimo (Kai Ni), Ushio (Kai Ni) or Shigure (Kai Ni) for doing AA cut-in (especially in the boss node) due to their high AA stats, reduces chances of damage from Nu-class flagship and Wo-class flagship
The boss BGM is 『吹雪』, the ending theme of the anime. However, the song will start on a different stanza than the one used in E-1.
Having 2 CLTs in second fleet may send you from F to G
Having 2 CAV goes from start to C
There is no battle at A, and E is a maelstrom node (fuel amount taken depends on how many radars your fleet has equiped, the more radars the less fuel lost)
LoS check from G to I
Battleship Princess at node H and I can always send your ship back home with 1 shot. Sparkling your ships is strongly recommended.
Having Ooyodo's Command Fleet Facility is helpful for getting to the boss node if someone in either fleet (except flagships) goes red, especially on the pre-boss nodes. Beware that on a C->E->H->K route, escorting a DD back on node C will cause E->F instead of E->H as E->H requires 3 DD and no CLT.
4 FBB + 1 CV + Akitsumaru (1st fleet) and 1 CL + 1 CLT + 4 DD (2nd fleet) will go either A->B->F->H->K or C->E->F->H->K (random). 4 battles total either way.
2 FBB + 2 CAV + 2 CVL (1st fleet) and 1 CL + 1 CA + 4 DD (2nd fleet) will go C->E->H->K. This is only 3 battles total and is probably the shortest route to boss. Though there is a fuel maelstrom at E.
[Quick Response] - 2 FBB + 1 CAV + 3 CV (1st fleet) and 1 CL + 1 CA + 4 DD (2nd fleet) works pretty well if you have the ships supporting this composition. Goes A->B->F->H->K or C->E->F->H->K (random). Usually using top right formation (survive) until the boss node, then switch to bottom right (battle).
2BB+1BBV+2CAV+CV (1st) 4DD+1CL+1CA (2nd) C->E->H->K Hard Mode
[Quick Response] - 1 BB 1 FBB 3 CV 1 CA (1st fleet) and 1 CL 1 CLT 3 DD 1 FBB (2nd fleet) will go A->B->F->H->K or C->E->F->H->K. There is a fuel maelstrom at node E.
[Quick Response] - 2 FBB 2 CAV 2CV (1st fleet) and 1 CL 1 CAV 4 DD (2nd fleet) will go C->E->H->K.
1 CA, 2 FBB, 1 BB, 1 CAV, 1 CV (main fleet) and 1 CL, 1 CA, 1 CAV, 3 DD (second fleet) will go either C->E->H->K or A->B->C->E->H->K (random).
[Quick Response] - 1FBB, 1BB, 1 CAV, 2CVL, 1CV (main fleet) and 1 FBB, 1 CLT, 1CL, 3DD (second fleet) will go A->B->G->I->K with LoS check from G to I.
The boss BGM is [海色] the Opening theme of the anime
E node Maelstrom, B node no battle, G is an easy transport node, and I node Night Battle.
The boss has a lot of fighters and good bombers, so using large capacity CVs like Taihou or Kaga is recommended.
Hard: 47 ELOS confirmed to reach boss.
The boss node flagship Aircraft Carrier Princess has 150 armor and 350 endurance, thus it is unlikely she will be damaged heavily without artillery spotting, strong night battle setups, or critical hits.
The First Class Medal is exchangable for 10,000, 10 Development Materials, 10 Improvement Materials, and 10 Large Furniture Boxes.
The First Class Medal SYMBOL which appears next to your name on your Admiral's Page is obtained TOGETHER with the medal item. Getting the medal item will automatically grant you the medal symbol. In short, ONLY E-5 hard completion is needed, the difficulty completed E1 to E4 does not matter. Please pay attention that if you CONSUME the First Class Medal for resources, the SYMBOL WILL DISAPPEAR!!!
Node C is an empty node, Node D is a fuel maelstrom.
Node A/B (higher conditions override lower)
Three or more carriers in the first fleet guarantees A.
Two or more CLT in the second fleet OR any submarines in the second fleet guarantees A.
Naka OR Agano OR Maikaze + Nowaki the second fleet will go to B.
If the first fleet consists of only fast ships, fleet will go to B.
Other fleets will go to A.
Having Akashi or Katori in the first fleet OR a submarine in the second fleet brings you from A to C, otherwise it random between C or D.
Generally Surface Combined Fleets are sent from D north to E, while Fast Response Combined Fleets are sent east to F.
