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

 * To get to the North Route (A Node) requires no CV in the fleet. This path has lower encounter with enemy fleet and has no carriers as well. (At least 2 battles)
 * Bring a CAV equipped with a seaplane bomber to allow your fleet to use Artillery Spotting.
 * This path is perfect for CA/V due that they can survive long enough (and versatile) for the boss battle.
 * Having a CV in the fleet will lead to the South Route (B node). This path will encounter more enemy fleets, but the best choice if players prefer a more brutal strategy.
 * Having 2 BB in the fleet has a 5% chance of heading to the Node F
 * There's some chance that compass will send you from E to H if your fleet don't have any large ship.
 * High LoS is needed (?) to get to the boss node.
