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

The below is based on and corrected from this table.
