Tips:

Do not bring CV or CVL into this map as fleet of fog ships have very high AA and firepower.
Depending on your HQ level, you may encounter Elite ships instead of the normal (blue) ones.
Always follow the upper path as it is the safest and shortest route to boss node.
At boss node, use line abreast formation to survive until night battle, when your fleet is at maximum power. Also pray for RNG to not let the enemy fleet of fog trigger klein field or Heavy Weight Laser Canon.

Additional info

Special "Arpeggio" permanent furniture will be available for purchasing for the duration of the event. All Arpeggio ships are temporary and will only last for the duration of the event.

Level recommendation to conquer E-1, E-2, and E-3:

E-1 is really easy you can clear it with level ~20

E-2 although star is similar to 2-4, it is way harder than it seem. Prefer your fleet can hold 3 gravitation cannon shot. Level 50+

E-3 same as above, prefer your fleet can chunk as much damage as you can. Kongou is tanky as hell so 90% of the time you have to kill her in night battle.
