Special Mechanics

1. Combined Fleet (E-3 and E-5)
2. Line of Sight requirements on some (all?) maps.
3. Selectable and Changeable difficulty
   • This event has 3 ranks: easy (丙), medium (乙), hard (甲).
   • You can choose the difficulty in each map separately.
   • Different difficulties give different medals, equipment and materials when clearing the maps.
   • Ships rewards (U-511, Katori and Amagi) will appear regardless of the difficulty.
   • Difficulties probably affect drop rates, but ships still drop in any difficulty.
   • 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.
4. There is no ship locking for this event.
5. The boss HP gauges does not regenerate over time in any map in any difficulty.
6. 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.

Branching rules 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 140 or higher . Such score not required on easy (100 is enough).
Tips Have some surface equip ready for Node G, H, And possibly I to avoid Moderate to Severe damage 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 usefull for increase LOS for node I The boss BGM is 『吹雪』, the ending theme of the anime.

E-2

Branching rules 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 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
Tips 2 FBB 2 CV 1 CL 1 DD 3 FBB 2 CV 1 DD 1 CLT 2BB 1 CV 1 CVL 1 DD (A-F-H-I) 3 BB 2CV 1CVL (B-C-F-H-I) 1 DD 1 CL 2CV 2FBB 2 BB 1 CA 2CVL 1CV 2CA(V) 2CL 2CV (Light Fleet Ver.) 2FBB, 2CV, 2CVL 2FBB, 1CAV, 1CA, 2CVL 2FBB, 1CV, 1CVL, 1CA, 1CL 2FBB, 2CV, 1CVL, 1DD 2FBB, 2CV, 1CAV, 1DD 1FBB, 1CV, 1CVL, 1CAV, 1CA, 1DD (A-F-G-I) 1CVL, 1CLT, 1FBB, 1BB, 1CL, 1CA(V) -- > (A-F-H-I) CLT can be taken, without 2CVL bound to going to maelstrom node 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.

E-3

Combined Fleet, sortie now! 『連合艦隊、出撃!』 Information Boss requires 4 kills to complete on Hard (甲). Boss requires 5 kills to complete on both Medium (乙) and Easy (丙). On final form, killing the flagship is required to destroy the bar. Combined Fleet Boss: (Node K) Light Cruiser Demon "damaged" (甲) Final Form: (Node K) Light Cruiser Demon "damaged" (甲) Rewards upon clear: Clearing on Hard (甲): U-511, 1 WG42 (Wurfgerät 42), 2 Medals, 4 Improvement Materials Clearing on Medium (乙): U-511, 1 WG42 (Wurfgerät 42), 1 Medal, 2 Improvement Materials Clearing on Easy (丙): U-511, 1 Medal
Branching rules Having a CLT in second fleet will send you E to F.
Tips 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).

E-4

Seize the Enemy Task Force! 『敵機動部隊を捕捉せよ!』 Information Single Fleet Takes 6 kills on on Medium (乙). Boss: (Node K) Aircraft Carrier Princess(甲） Rewards upon clear: Clearing on Hard (甲): Katori, 1 Medal, 6 Improvement Materials Clearing on Medium (乙): Katori, 1 Medal, 3 Improvement Materials Clearing on Easy (丙): Katori
Branching rules At least 2DD is REQUIRED to reach the boss. Having Naka or Agano in your fleet sends you from B - D
Tips Heavy AA on boss, using heavy AA CV's like Taihou or Kaga reccomended. 47 ELOS Hardmode confirmed to reach boss. Recommended Formation: 2 FBB 2DD 2CV. 2BB 2DD 2CV (include a ship that's slow). Goes BFHJK consistently. 2 CA 2 CAV 2 DD. Goes southern route. 2BB(slow) 2DD 1CV/CAV and Naka or Agano guarantees Southern route to Boss. 2 CA+ 2CAV + 2DD suggest Myoukou, Prinz Eugen, Yukikaze, and Shigure for CI going B-D-G-I-K High luck stat DD (ex: Yukikaze, Hatsushimo) is very useful for cut-in attack during night battle. Especially for Hard difficulty, boss node support expedition is (very) recommended.

E-5

Decisive Battle! Combined Fleet, Begin Counterattack! 『決戦!連合艦隊、反撃せよ!』 Information Combined Fleet Boss:(Node J) Battleship Water Demon "damaged"(甲） Rewards upon clear: Clearing on Hard (甲): Amagi, 2 Medals, 8 Improvement Materials, 1 First Class Medal Clearing on Medium (乙): Amagi, 2 Medals, 6 Improvement Materials Clearing on Easy (丙): Amagi, 1 Medal The First Class Medal is exchangable for 10,000, 10 Development Materials, 10 Improvement Materials, and 10 Large Furniture Boxes. Node C is an empty node, Node D is a fuel maelstrom.
Branching rules Naka or Agano plus 1 or fewer CLT will guarantee B node from start. Having Akashi or Katori in your first fleet OR a submarine in your second fleet brings you from A to C, otherwise it seems to be random whether you get sent C or D. Surface Combined Fleets are sent from D north to E, while Fast Response Combined Fleets are sent east to F. G and H/I are random. More than 2 CLT will deadend.
Tips There is a chance of meeting Light Cruiser Demon in the first node. Aircraft Carrier Demon awaits you at the pre-boss node. On the final boss kill for hard difficulty, Battleship Water Demon awaits you with an escort of 2 Battleship Princesses, Standard Carrier Wo-Class Flagship II, and 2 Heavy Cruiser Ne-class elites. Surface Combined Fleet is highly preferred since it is better able to defend the second fleet until the boss battle. Cut-in setups and night battle equipment are highly recommended for the boss's final form. Fighter power of 252 is needed for hard mode pre-final kill air superiority at the boss. This is achievable with 2CVL + 1BBV or 1CV + Akitsumaru + 2BBV Fighter power of 126 is needed for hard mode final boss formation air superiority. This is achievable with 1CV Katori Kai is recommended as flagship to avoid the fuel maelstrom while holding the Fleet Command Facility. Pre-boss support expedition is recommended. Boss support expedition is recommended for final form.
