World 2

Stage Guide

 * 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.
 * 3 SS, 2 CV, 1 DD go to boss node frequently.

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

Tips

 * 1) If you aiming for the boss node and end up going A-B route on 2-4, just end the sortie. You will run out of fuel/ammo by the time you get to boss node. For highest EXP gain, end it around at G-H-I node.
 * 2) A-F route will guarantee you a boss fight.
 * 3) 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 hoping you get to boss.  It is possible to clear it with a single moderately leveled sub with a lot of luck.  Consider farming 1-5 if you are in need of subs.
 * 4) A more conventional way to finish 2-4 is using 「BBx4 CVx2」or「BBx3 CVx3」. (BBs are stronger; Modernizing/Leveling them is highly recommended).
 * 5) It is strongly recommended to make use of the Artillery spotting and Night Combat mechanics to deal higher damage.

Minimal conditions for victory:

B - At least 1 damage to enemy, no damage taken (SS route) / Defeat enemy flagship

A - Sink at least 4 out of 6 enemy ships

Stage Guide
Certain amount of LoS is needed to reach boss node. LoS calculation is unclear but equipment LoS seems way effective than ship LoS.
 * Large ships=BB/BBV
 * Medium sized ships=CA/CAV
 * Carriers=CV/CVL

Currently recommended fleet composition All BB/CA/CAV/CL are recommended to be equipped with radars/recon seaplanes/seaplane bombers.
 * Fleet of atleast 4CA/CAV +DD/CL - High chance reaching boss and cost efficient but lower survivability
 * 4FastBB 2CV - High survivability but high chance straying B-F and high resource consumption.
