Participation requirements
''' Check if you fulfill these requirements if you can't sortie to event maps! '''
 * Must have a 75% sortie win ratio
 * Must have 5 empty ship slots for new ships
 * Must have 20 free equipment slots
 * Must have formed a Combined Fleet to sortie in E-2, E-4 and E-6, and no combined fleet for E-1, E-3, E-5.



Special Mechanics

 * 1) Selectable and changeable difficulty
 * 2) *This event has 3 ranks: easy (丙), medium (乙), hard (甲).
 * 3) *HQ Level 35 unlocks medium, HQ Level 80 unlocks hard.
 * 4) *You can choose the difficulty in each map separately.
 * 5) ** However, this time around you will not be able to jump up the difficulty from Easy -> Hard after a map. To be able to use "Hard" setting, you must clear the previous map either on Medium or Hard itself. Only jumping up two difficulty levels is not allowed, other combinations stick to the old rules.
 * 6) ***【 BAD 】 Easy  >  Easy  >  Hard  (not possible because easy jumped to hard)
 * 7) ***【OK】 Easy  >  Medium  >  Hard 
 * 8) ***【OK】 Medium  >  Easy  >  Medium 
 * 9) ***【OK】 Medium  >  Medium  >  Hard 
 * 10) ***【OK】 Hard  >  Hard  >  Easy 
 * 11) ***【OK】 Hard  >  Hard  >  Medium 
 * 12) *When the difficulty is changed, the boss's health bar will be reset.
 * 13) *Once the map is cleared (boss HP bar is depleted and killed), you CANNOT change the difficulty anymore, but can still farm the map on difficulty used to clear it
 * 14) *Different difficulties give different medals, equipment and materials when clearing the maps.
 * 15) Combined Fleet in E-2, E-4 and E-6
 * 16) Manual Selection - As seen in many maps, you can manually select the path that you wanted to go instead of relying on RNG or branching rule to bring you there.
 * 17) Aerial Combat - In some map, you'll notice that there's only Air combat, which happened twice instead of the usual combat. This is an Aerial Combat node where only your CV/CVL or other ships with launch-able planes will do the combat.

Event Maps
See Enemy Encounter Reporting threads for detailed formation on each node. Special Note: In this event, After clearing a map, it is reported that the boss' pattern will revert to the original form, unlike previous events.

Regarding Drops with "Shipname (Difficulty +) Format

In drop reports, red ship names indicate that drops have only been observed from S-rank victory. Some of the ships would be listed as "Shipname (Difficulty +)." For instance, if it reads Isokaze (Medium +), that means that, so far, reports say Isokaze mostly drops for Medium or above, that does not mean Isokaze does not drop in Easy, just that there haven't been sufficient reports to show Isokaze also drops in easy difficulty. And also, just because drop reports exist does not mean the drop rate would be equal across different difficulties, and the accuracy of those reports is not 100% guaranteed.
