World 5

Tips

 * Two CA/CAV to guarantee sortie start->A, and H -> I (boss) route
 * Two DD for C to H.
 * Node D is an all sub node, Node A has 2/3 chance of having one sub, and Boss Node I 1/3 chance of having one sub
 * A convenient place to level subs. Node D is all subs--neither side can harm each other--and rewards 750 exp for a D rank clear, though moving to node A can result in heavy damage.

Tips

 * Killing the boss will bring down map meter 25%. You need to defeat the boss 4 times, and she will turn into a stronger form in the last battle. Map meter does not regenerate.
 * Considering the difficulty of the map compared to others, this is a very good map to train on if you are bored with 3-2. Bar Node G, you can intentionally send fleets to get you to node J and generally defeat easy fleet comps. This is not resource or repair friendly though (since you will get damaged one way or another).

Tips

 * All nodes, except end nodes, are night battles only; there's also a submarine node if you have any slow ship in your fleet.
 * Sinking the Flagship Wa-class transport ship at the boss node will lower the boss gauge by 20%. You need to do this 5 times to clear the map.
 * 2DD, fast ship, and high torpedo stat (for night battle) is recommended. You can also use an all submarine fleet, but it will often be directed to J instead of Boss.
 * Taking advantage of night battle equipment (Star Shell, Searchlight, Type 98 Recon Seaplane (Night Scout) ) is recommended and Sparkling your ships should be considered as well.
 * Unless you need S rank for drops, you do not need to destroy the Hime and can bring a light fleet to deal with the Flagship Wa-class transport for map clear purpose.
 * There's a gold submarine in the boss node. A possible tactic is to bring 1 CL flag with heavy ASW gear and 5 DD, enter battle in Line Abreast formation to deal with it quickly and get less damage from enemy ships, to focus on night battle. This fleet composition is the most resource efficient and can often succeed. Try double line or echelon on pre-boss nodes to better absorb enemy cut-in attacks.
 * Another possible strategy is to run 2 Fast Battleships, 2 CA(V) and 2 DD. This has a high chance of reaching the boss node and can get a lucky kill on the Wa-Class, but is extremely expensive in fuel, steel and ammo. Make sure not to equip bomber seaplanes so that your ships do not target the SS.  A variation of this is to replace 1-2 CA(V) with CLT, but 2 CA(V) should be used for the final form because of the changes in boss composition.
 * A possible strategy is to run 3 CLTs, 1CA(V), and 2 DDs. This is the most efficient with highest Attack power/torpedo and possible to lowest encounter rate (C-D-I-K)
 * Akitsumaru can do air superiority at boss node with at least 2 Reppu + Type 52 Zero Fighter or 3 Shiden Kai 2 so your fleet can perform artillery spotting and prevent enemy ship do artillery spotting to you. Keep in mind that she is slow ship so you will suffer at submarine node instead.
 * Both enemy and ally submarines do not have increased evasion during battles STARTING at night, i.e. hitting them is as easy as in any day battle.
 * The last possible tactic is to send a fleet consist of 4 or more SS. This composition is very resource-efficient, but the drawback is a low chance of going to the boss node from I(16%) This low chance is often offset by the higher rate of making it to the pre-boss node without suffering critical damage. A SS fleet tends to go to node B, where you can avoid damage by getting a C rank.
 * If you are willing to sacrifice to achieve your goals, a variation of the composition is to use 4 SS with two disposable DD to meet the branching requirements. Use Line Abreast at node B to increase evasion vs enemy SS. If both DD survive, you have a very high chance of going to boss node when compared to pure SS fleets.(Bring support expedition for boss to gain confidence)

Tips

 * Like 5-3, you must sink the boss battle flagship 5 times to complete the map.
 * Clearing this map with a Submarine Fleet consisting of 5-6SS is possible; However, there is a high chance that your SS won't hit the Flagship in the boss node.
 * Using level 60+ SS (with at least maxed armor and torpedo stat) is advised, since there are several flagship DD and CL equipped with sonars and depth charges..
 * Nodes G and I are night battles.
 * Node I is a submarine node.
 * Node H contains Carrier Demons while nodes K and N contain Carrier Princesses
 * For farming rare ships, Admiral exp or just boss kills to unlock 5-5, recommended formation is a flagship that can carry 4 drums (Yuubari, Ooyodo, CAV), any combination of 3 FBBs and/or CLTs, and 2 CVs. With this formation you only need to fight Nodes A and H before reaching the boss. Using Diamond formation at Node H also reduces the chances of enemy ships targeting your flagship.

Stage Guide

 * You must sink the Boss Standard Carrier Wo-class Kai Flagship 5 times to clear the Map.
 * Nodes C, H, K and M are night battles.
 * Having 4 ships capable of equipping Drum Canisters (DD/CL/CAV) and a total of 5 Drum Canisters will take you to node B. Other compositions will always take you to node A.
 * Fleet with 3 SS or more will take you to node F, where there are enemy CLs and DDs with ASW.
 * Fleet with only fast ships will take you to node D. It is possible to bring slow ships if the fleet has 2 CV and 1 CVL. Other composition will take you to node C, where you will meet 6 enemy SS in night battle.
 * The recommended fleet composition is 3 BB, 2 CV and 1 CVL for maximum firepower and survivability.
 * There is a sub at the boss node. Getting S rank at the boss is possible, but not recommended. It is advisable to ignore the sub and just settle for an A or B rank.
 * Using submarines in the map (3 BB 3 SS) taking you to A-F-G-N is possible. 3+ SS gets you to node F but more than 3 SS gets you to node H instead of N.
 * Clearing this map rewards 1 medal and 200 points for ranking. The boss HP bar is reset at the beginning of each month, allowing the reward to be obtained again.
