Stage Guide
Tips
 * You are required to SINK the flagship at boss node 4 times to clear the map.
 * A certain amount of eLoS is required to reach the boss node:
 * Below 31 (using the new formula 33; 57.2 for 2-5 fall formula) will not go H to L
 * 33 or more (using formula 33; at least 70.4 for 2-5 fall formula) guarantees H to L
 * There are 3 routes to the boss node:
 * North route, 3 battles (A-D-H-L)
 * South route I, 3 battles (B-E-H-L)
 * South route II, 4 battles (B-E-I-L)
 * North route, 3 battles (A-D-H-L):
 * Only two battles before the boss node. The second node is a night battle node
 * Recommended fleet composition: 2CAV 3CA(V) 1CLT, 1CA 1CL 4DD
 * No BB(V) or CV(L) are allowed for this quest composition
 * Two ships need to be equipped with a Drum Canister in order to guarantee node A OR have at least 3DD + 1DD or 1CL; otherwise, you risk being diverted to B.
 * It's possible to bring 0-2 CLT
 * Useful for their opening strike for easier Node A but too many will make reaching the required eLoS difficult (more feasible at lower levels).
 * North route (including boss node) doesn't have any enemy carriers, so it's possible to get AS+ with just seaplane bombers, enabling Artillery Spotting
 * The monthly quest Bm7 forces you to go through this route. Order your fleet as DD-CA-CL-DD-DD-DD to maximize the efficiency of the firing order while also meeting the requirement for the quest.
 * Double attack setups (both day and night) are recommended for consistency
 * Consider bringing Star Shells, Searchlights and/or Type 98 Recon Seaplanes (Night Scout) to make the night battle and boss node easier.
 * South Route I, 3 battles (B-E-H-L):
 * Only two battles before the boss node
 * Recommended fleet compositions: 2CA/CAV 2DD 2CVL; 3CVL 1CL 2DD
 * No BB(V) or CV allowed
 * 2 DD are needed to secure this route
 * Use either 2 CA or 2 CAV. Mixing CA/CAV can lead to I instead of H.
 * This route has an enemy carrier on the first node and BBs, which can easily damage low-armor ships. You are advised to bring high-level ships.
 * South Route II, 4 battles (B-E-I-L):
 * Three battles before the boss node
 * Recommended fleet compositions: 4FBB 2CV; 1(F)BB(V) 3CA(V) 2CV; 6CVL; 3 CA(V) 3 CVL
 * Heavy fleets have a chance of off routing to node F, a dead end.
 * This is recommended to players with ship levels below 50 as it can cause fewer retreat than other composition despite being more expensive.
 * 6CVLs is a viable option due to its strong opening; however, it can also lead to node F. It may go through South Route I while evading node I: 6 CVL
 * Summary:
 * North route, 3 battles (A-D-H-L):
 * (+) low resource consumption
 * (+) hardly any bauxite lost or none at all
 * (-) usually has the most issues getting the required value, depending on your fleet
 * (-) night battle node, which will usually be the cause of your retreats
 * (-) strong ships needed to deal with the boss node
 * South route I, 3 battles (B-E-H-L):
 * (+) low resource consumption & repair costs
 * (+) no night battle node
 * (+) able to bring light carriers
 * (-) you need strong planes and carriers for this to be reliable
 * (-) weaker ships are vulnerable due to the enemy battleship
 * South route II, 4 battles (B-E-I-L):
 * (+) a very strong fleet
 * (+) no night battle node
 * (-) has a high chance of dead-end
 * (-) has a chance to encounter
 * (-) high resource consumption & repair costs

Quest Guide
Sortie Quests= These are the quests that are related to World 2-5.

Please note that if the quest's composition is similar, it will be sorted under the same tab and the most notable one will be featured. Such cases are as followed:
 * Under Bm1 : B34
 * Under Bm7 : B57, B59, B79
 * Under B85 : N/A
 * Under B100 : N/A
 * Under B102 : B114

The following quest is not listed as you can clear with basic setup. Common Composition: 3-4 CA and 2-3 Wildcards Possible Route: North and South  Bm1  - North Route  B34 - North Route Common Composition: 3+ DD and 3 Wildcards Possible Routes: North and South  Bm7 - North Route only  B57  - North and South Route  B59  - North and South Route  B79  - North and South Route  B85  - North or South Route  B100  - North or South Route  B102 and B114  - North Route
 * C15
 * -|Bm1=
 * Required: 3 CA -, ,   + 3 Wildcards
 * Suggested - North:, ,  + 2 CAV + 1 CA/CLT
 * Equipping 2 Drum Canisters, one on each CAV.
 * Equip Zuiun on CAV for easy air superiority)
 * Add another CLT gives you an opening strike but makes it harder to reach eLoS at node H; adding another CA has vice versa effect of CLT.
 * Suggested - South II:, ,  + 3 CVL
 * There is another additional battle and having a chance to derail to dead end, F node; however, the opening strike of the CVLs and air superiority provide enough support to make up for its cons.
 * Required: 4 CA -, , ,  + 2 Wildcards
 * Suggested - North:, , ,  + 2 CAV
 * Additionally, similar suggestion can be given by using 2 CVL instead of 2 CAV and go South route II.
 * -|Bm7=
 * Required: 4DD (DD as flagship) + 1CL + 1CA (Not CAV)
 * Due to 4 DD and no composition leeway, this composition will be forced to go north no matter what. In addition, there is a line of sight requirements from node H to boss node making this quest one of the more challenging one:
 * All destroyers will need radars and is unlikely to equip any night battle equipment. Try balancing between ships that can provide high firepower and ships that has good base LoS (or both):
 * is useful as she is currently the only DD that can equip Large radar (e.g.Type 32 Surface Radar), allowing you some space to equip other equipment (e.g. Searchlight).
 * is great due to her high base LoS and decent firepower.
 * Some other candidates are (not D),, , ,, and.
 * CA will probably need 1-2 seaplanes to gain enough LoS.
 * is currently the best CA to use with her ridiculously all-high stats (except luck) compared to all other CAs. In addition, her high FP and base LoS (losing LoS only to the Tone-class Kai) makes her the ideal ship for this quest.
 * Otherwise,, ,  ,  are also viable selection.
 * Having or  will allow you to bring seaplane bombers (e.g. Zuiun) despite using a CA, allowing you to achieve Air Superiority
 * CL might need to have 1-2 seaplanes equipped to bring the fleet up to the required LoS.
 * Four-slot CLs such as are especially useful for this as you do not sacrifice double attacks at night; her Base LoS is the highest among the CLs and one of the highest in the game., another 4-slot CL, can also carry seaplane despite her 0 slot; however, she has the lowest base LoS of all the CL-kai.
 * It is possible to use for her opening torpedo, but you need to distribute your LoS carefully.
 * Stat-wise, and  are strong CL due to their ridiculously high stat despite being a Kai-ship, but having no unique gimmick like those previously mentioned. Sendai-class Kai ni are also viable with a bit more base LoS; Kuma and Nagara do cost less in terms of ammo than the Sendai-class Kai ni.
 * Required - North: as Flagship,, , ,  + 1 Wildcard
 * Since 1 Wildcard is allowed, another CA is highly recommended since it gives you decent firepower while lessening your load on LoS as you can bring additional seaplanes. Other options (CLT or Abukuma opening torpedo) are possible.
 * Alternative - South: On the other hand, you can use 1 CVL (avoid dead end and possibly node I) and go South Route I instead. LoS became a lot less problematic when you have carriers.
 * Required: as Flagship + 2 DD + 3 Wildcard
 * Even better, a lot more wiggling room. Follow suggestions as above, but remember that now, you can equip up to 2-3 CA for easy LoS along with possibly 0-1 CLT.
 * Alternative - South: With even more flexibility, you can even do 3 CVL and go, mostly, South Route I (still can derail to I).
 * Required:, , , + 2 Wildcard
 * Only A-rank is needed
 * As above, but with 1 less wildcard. But a bit more difficult due to the 4 DD restriction. This forces you to plan your fleet carefully since you are not bringing any unique stat ships with you other than Ayanami. Depending on your preference, you can choose what your 2 wildcards will be. However, you must consider the fact that the base LoS stat from will be lower than if you sortie, let's say, Akatsuki.
 * Alternative - South: As above but with 2 CVL instead. Bringing CVL will help deal with LoS requirement but traded with going through a node with BB.
 * -|B85=
 * Required:   as flagship + 5 of the following 6 members:, ,  ,  ,   and/or
 * Since you can only bring 2 DD at max, this allows you to pick between a definite North route (i.e. put Drums) or a random South I Route (no drums)
 * There is a small wiggling room for this quest. As you only need 5/6 of the ships, the only ship that you must pick no matter what is.
 * Due to the LoS requirement, night battle equipment may not be possible to bring and your fleet's fire power might be low. Consider this fact when you want to bring drums for definite A node too.
 * DD - and/or  is recommended to be outfitted with only surface radars (e.g. Type 33 Surface Radar) to give other ships more firepower. Although, giving them 2 Guns + 1 Radar is viable but other ships will suffer.
 * CL - and/or  will also need radars and/or seaplanes.
 * CA - is recommended to have two seaplanes + 2 main guns.
 * CLT - and/or   is recommended to have their normal configuration of 2 Guns and Kouhyouteki.
 * -|B100=
 * Required:  1 Light Cruiser, 2 Destroyers or Coastal Defense Ships, 1 Aviation Cruiser or Light Carrier, up to 2 additional ships
 * The reason that this quest is separated from the rest is because of its freedom to go either north or south despite leaning toward the north:
 * North: This will bring you back to the Bm7 composition-like, but your composition will be 3 DD 1 CL 1 CA(V) and two wildcards.
 * This gives you more relaxation on your LoS because of CAV's higher Base LoS and your freedom to bring two other ships. Everything else, just look at Bm7's tab.
 * South: South is plausible with the composition:
 * 1 CL 2 DD 2 CA(V) and 1 CVL
 * A carrier will force you south. Use the advantage of forcing you to bring 2 DD to go the B-E-H-L (2 battles) route by adding an additional 2 CA(V) to your fleet. The CVL will help you deal with Air Denial if you happened to meet the carrier at node B, and give you Air superiority and Air-strike power. Make sure you bring at least one fighter to reach AS.
 * 1 CL 2 DD 3 CVL
 * Similar to above but with stronger Opening Strike.
 * -|B102=
 * Required:   and  (both above level 50) as flagship and 2nd ship with 1 Light Cruiser, 2 Destroyers and 1 additional ship.
 * For B114, and  do not need to be at specified position. Positioning is flexible; everything else is the same.
 * This is a peculiar quest. Not only is there a minimum level, but it also forced you North with 2 BB. This will most likely be your fleet's composition that provides certain routing:
 * ,, 2 DD, 1 CL + 1 DD/AV/CA
 * Due to the presence of both Ise and Hyuuga, you are not allowed to go South route as it will always lead you to Node F, a dead-end. Therefore, the only other option left is to go north.
 * DD/AV is suggested if you wish to satisfy the routing requirement without/with drums.
 * CA is considered because of their efficiency at both day battle and night battle node compared to BB(V)/DD. Equip two of your DD/CL with at least 1 drum if you wish to bring a CA. However, there's a chance to get off routed to Node G due to random routing.
 * Node D (night battle) will be the usual; just survive it.

Note
Akashi will drop with a small chance in 2-5 only for Admirals who do not currently own her. So, if you already have had her but sunk/scrapped/used her in modernization, she will drop in this map again.

Trivia

 * The LoS value required to have 100% chance of going to the boss was 38 in F33 or 70.4 in 2-5 Fall formula before Bm7's implementation in December 2014, but is reduced to 33 in F33 after the implementation.
