Tips

 * 1) A fleet with CVL is more likely to go to node K.
 * 2) If you are aiming for the boss node to clear the map and failed to take the A-F route, it is recommended to just end the sortie.
 * 3) A-F route will guarantee you a boss fight and take only 3 fight before boss node because node G will always be avoid battle node if your fleet comes from node F.
 * 4) On the other hand, A-B-C-D-G route is impossible for boss clear. Approaching G node from D node will result in enemy encounter (red node) and you will run out of fuel and ammo (5 battles) by the time you get to boss node, causing you to do only scratch damage. If you still wish to continue, for highest EXP gain, end the sortie around the G-H/-I node.
 * 5) A most conventional way to finish 2-4 is using 「BBx4 CVx2」or「BBx3 CVx3」. (BBs are stronger; Modernizing/Leveling them is highly recommended). 「BBx2 CVx4」 may be slightly cheaper for high-level fleets with strong fighters and bombers.
 * 6) It is strongly recommended to make use of the Artillery spotting and Night Combat mechanics to deal higher damage.
 * 7) Subs can be a cheap way to clear the map, but will require a lot of patience. This generally involves trying over and over so you can avoid the highly dangerous line abreast formations and get to the boss node. It is possible to clear 2-4 with a single moderately leveled, maxed armor sub. Consider farming 1-5 if you are in need of subs.

Sample Fleet and Equipment Setup
Beginners are recommended to try to follow these exact setups as much as possible.
 * Note to Beginners: You do not need to gain S-Rank Victory on the Boss node to clear this map. Just obtain rank B or higher victory and you will be able to clear the map.
 * The ships do not have to be the exactly the same ship as listed in the sample.
 * Ex. Kongou Kai who is in the sample can be Kirishima Kai instead, or Nagato Kai, or even Hyuuga Kai, depending on the Battleship you have in your fleet.


 * You are recommended to follow the equipment setup, but exceptions may occur where you might need to equip more fighters or more seaplane bombers for the extra fighter power.
 * You need at least 123/246 fighter power to get AS/AS+ respectively assuming you have to go through node H.

Fleet: 4 Battleships (BB/BBV/FBB) and 2 Standard Aircraft Carriers (CV)

Fleet: 3 Battleships (BB/BBV/FBB) and 3 Standard Aircraft Carriers (CV)


 * 1 CV can be substituted by a remodeled (kai) CVL.

Fleet: 2 Battleships (BB/BBV/FBB) and 4 Standard Aircraft Carriers (CV)
 * 1 to 2 CV can be substituted by 1 to 2 remodeled (kai) CVLs.

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
 * 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; otherwise, you risk being diverted to B.
 * It's possible to bring 0-2 CLT
 * Zero makes the first node more dangerous because it's more likely for an enemy to survive until the torpedo phase. On the other hand, a high level (Kai ni) CA or Prinz Eugen Kai are more sturdy and less likely to get one-shot to heavy "red" damage.
 * Two makes achieving the necessary ELoS to reach the boss more difficult; but it is feasible, especially at lower HQ 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
 * 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.
 * (For quest BM1) 3CA (Haguro, Myoukou, Nachi), 2 CAV (Needed for branching. Equip Zuiuns for easy air superiority), 1 CLT
 * One CAV can be swapped out for another CLT, but you risk being diverted to B node in exchange for another powerful opening strike to survive node A.
 * Alternatively, carry at least two drum cans on the CAVs (one on each) to ensure branching to A node, with the Zuiun on the largest plane slot
 * (For quest BM7) 4DD (as flagship), 1CL, 1CA (No aviation cruisers)
 * Because of the line of sight requirements of H to boss node, having the necessary equipment means that all destroyers will have to be outfitted with a radar and will not have any night battle equipment (stack as many radars on DDs as required to reach the required 70.4 LOS), and that the CA will have to have two seaplanes to gain enough LOS. In most cases, the CL will also need to have two seaplanes equipped to bring the fleet up to the required LOS. Four-slot CLs such as Ooyodo are especially useful for this as you do not sacrifice double attacks at night
 * Yuubari can be used as a substitute for Ooyodo, but be mindful of her lower armor and evasion, as well as lower base LoS.
 * It is possible to use Abukuma Kai Ni if you use 1 Kohyouteki + 2 Seaplanes as you will give up the night DA but still have the opening torpedo.
 * Here is an example (Abukuma Kai Ni + 1CA + 4DDs with one as flagship)
 * (For quest B85 HQ lvl > 110) 1CA 1DD 2CLT 2CL
 * Because the LOS requirements of H to boss node you will not have any night battle equipment and your fleet's fire power will be low, so to reach boss node use Line Abreast on node A and D with your fleet sparkling for better results.
 * The destroyer (Uranami or Shikinami) will have to be outfitted with only surface radars (Type 22 Kai 4 or Type 33 Surface Radar) for the LOS requirements.
 * Both CL (Kinu K2 or Kuma) will require one surface radar (Type 32 Surface Radar or better) and one of them must be outfitted with one seaplane. (You can exchange on one of them the radar and put another seaplane).
 * The CA (Aoba) will need to have two seaplanes + 2 main guns.
 * The 2 CLT (Ooi and Kitakami) can have a normal configuration of 2 Main Guns or 2 Auxiliary Guns + 1 Kohyouteki.
 * South route I, 3 battles (B-E-H-L):
 * Only two battles before the boss node
 * Recommended fleet compositions: 2CA/CAV 2DD 2CVL; 2CA/CAV 2DD 1CLT 1CVL; 3CVL 1CL 2DD
 * No BB(V) or CV allowed
 * 2 CA/CAV 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 enemy carriers and BBs, which can easily damage low-armor ships like DDs, so bringing high-level ones is recommended
 * 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; 1FBB 1BB 3CA 1 CVL; 6CVL
 * Heavy fleets like these can go to node F, a dead end [20%]
 * There seems to be certain factors that might reduce the chance to go to the dead end:
 * Using as few BB(V) or CV as possible
 * Using BBV instead of BB
 * Using CAV instead of CA
 * The compo is recommended to players with their ship level below 50 as it would cause fewer retreat than other compo despite being more expensive.
 * 6CVLs may be the best fleet, since it has a very strong opening, it is unlikely to get heavily damaged and can sink at least half of the enemy fleet before the Shelling Phase; however, it can lead to node F and requires a lot of good Bombers (e.g., Ryuusei Kai). Also, make sure you have enough LOS to reach the boss node. It is recommended to use Torpedo Bombers, 1 Carrier-based Reconnaissance Aircraft (Yellow plane), and enough Fighters planes to get at least AS at node I (Here is a video demonstration). Also, it may go through B-E-H-L while evading node I


 * 1 BB(V) 1 BB 1 (F)BB 2 CA 1 CV also have a chance to go to boss node (tested) ~
 * Summary:
 * North route, 3 battles (A-D-H-L):
 * (+) low resource consumption & repair costs
 * (+) hardly any bauxite lost
 * (-) fairly difficult night battle node
 * (-) high-level CA(V)s 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
 * (-) 2 DD are needed due to branching rules; enemy BBs can damage them easily
 * (-) high-level ships are needed to deal with normal nodes and the boss
 * South route II, 4 battles (B-E-I-L):
 * (+) strong fleet with low chance of forced retreat due to heavy damage
 * (+) no night battle node
 * (-) has a high chance of dead-end
 * (-) high resource consumption & repair costs

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.
