World 2

Tips

 * This is a good place to finish Bw2 (20 CV/CVL) since all end nodes consist of 2-3 CV/CVL in every enemy's fleet composition allowing you to finish it in at most 10 runs while possibly finishing your Bd7 (5 Bosses) along the way.

 * 70% chance Node E to F (Boss Node) if fleet contains one or more of the following: CV, CVL, or AV.
 * 70% chance Node E to G (Transport Node) otherwise.

Tips
A perfect place for low level HQ Admiral to catch some BB class. Just make sure you got atleast 2 CVL/CV Loaded with torpedo and fighter Aircraft. The fastest route & easy way to clear quest : Daily  [Bd4,Bd5,Bd6,Bd7]. Weekly [Bw3,Bw4,]

 * 70% chance for Node I to J if fleet contains CL, otherwise it's 50/50.

Tips
After you level your submarines above level 20 and upgrade them to 4-5 stars, you can use them to grind 2-3 for some Daily and Weekly quests, as well as picking up resources.

1. A fleet which contains at least 3 submarines is recommended. The more submarines you use, the easier clearing the map will be.

2. Submarines with high luck should be placed at the bottom of the fleet list to increase their chance of performing cut-in attacks on the stronger enemies during night battles. Doing this can help you achieve an A or S rank victory, especially if you have to fight the enemy fleet located at node G.

3. Submarines should be fully modernized (at least fully upgraded torpedo attack and armor) and non-remodeled because non-remodeled submarines don't cost very much time to repair or very many resources to resupply (especially ammo). Please note that compared to a non-remodeled submarine, a remodeled sub will take twice the amount of time to repair.

4. This method does not guarantee victory every time, especially if you hit the boss node and have an unlucky run.

Trivia
You can do B14 OR B19 AND B17 Quest at the same time. 1 boss for 2 quest. you can mix B20 with B17, (not recommended since lack firepower)

Tips
Note: It is good to know the probability of clearing the map with subs. You are required to obtain at least B-rank to clear the map. Considering A-F route, you have 1/4 chance to meet an Anti-sub Fleet (ASF) in node A, 1/3 chance to go to F node, 1/2 chance to go to ASF at node I and another 1/2 chance of ASF fleet at node I. Lastly, you have to clear the boss node. If you can damage the enemy's DD/CL/CA in the boss node while taking scratch to no damage you can achieve B-rank via damage comparison.
 * 1) If you are aiming for the boss node and end up going down the A-B route on 2-4, just end the sortie. You will run out of fuel and ammo by the time you get to boss node. For highest EXP gain, end the sortie around the G-H/-I node.
 * 2) A-F route will guarantee you a boss fight.
 * 3) A more conventional way to finish 2-4 is using 「BBx4 CVx2」or「BBx3 CVx3」. (BBs are stronger; Modernizing/Leveling them is highly recommended).
 * 4) It is strongly recommended to make use of the Artillery spotting and Night Combat mechanics to deal higher damage.
 * 5) 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 sub with a lot of luck.  Consider farming 1-5 if you are in need of subs.

Tips
 * Medium sized ships=CA/CAV/CVL
 * Small sized ships=DD,CL?CLT?
 * 1 CL, 2 CLT, 2 Fast BB, 1 CV appears to go B -> F 100% of the time. This fleet composition requires more tests runs to determine an exact branching rule.
 * 1 CL, 1 CLT, 1 CA, 2 Fast BB, 1 CV appears to go B -> F.


 * 2 CVL, 2 CA(V), 2 DD or 1 CVL 1 CLT 2 CA(V), 2 DD are recommended compositions with a 100% chance to reach the boss by southern route in 3 battles. CA/CAV cannot be mixed.
 * You must still meet LoS requirements to reach the boss node.
 * 2 CV, 4 Fast BB, will usually reach the boss through B -> E -> I -> L. There is about a 25% chance of getting sent to the dead end after the first node.
 * You must still meet LoS requirements to reach the boss node.
 * 1 Fast BB, 1 BB, 1 CVL, 3 CA can reach boss node through B -> E -> I -> L. There's a small chance of getting sent to the dead end after the first node.
 * Not as good for those with HQ level more than 100, as 'I' node will have Wo-class Flagship Kai requiring 150+ air superiority.
 * BBV can be substituted for BB, but roughly 25%-30% chance of going to Node F dead end after first node.
 * 6 CA(V) with minimum of 2 CAV carrying 1 drum each for the total of 2 drums. This composition will guarantees north route.
 * There is night battle at node D, remember to equip search light and star shells. Choose echelon formation for max evasion.
 * You may replace CA with CLT provided that you can compensate for the loss of LOS. It is recommended not to use more than 2 CLT.
 * You must still meet LoS requirements to reach the boss node. (Approximately 75+ ELOS for Lv 100+ HQ)
 * Tactically, flagship selection is vital because nodes D, E, and (usually) I will go to a lineup order round of attacks and the enemy flagship is by far the strongest. High damage output is preferred to preemptively damage/sink the enemy flagship before their attack.
 * Equipping a searchlight onto the flagship and/or star shells is recommended if taking the northern route.
 * 2*(Recon Plane LoS) + Radar LoS + √(all other LoS) ≥ 76 required to go H-L. However, H-L is not guaranteed by meeting this requirement.
 * Thus, all BB/CA/CAV/CL/DD are recommended to be equipped with radars/recon seaplanes/seaplane bombers.

Note
Akashi will drop with a small chance in 2-5 only for Admirals who have never gotten her before. If you already have her, she will not drop in this map anymore. However, Akashi is still obtainable in maps like 3-5 or 6-2.
