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.

2. Complete Crafting Quest: You will be required to scrap 4 pieces of equipment. Do it one by one as the game will consider discarding multiplies at once, as one time
