Partials/Difficulty Selection

Difficulty Selection

 * This event has three (3) difficulty selections or otherwise known as ranks:
 * easy (丙) (Available from HQ level 1 and spans up to level 35)
 * medium (乙) (Unlocks at HQ level 35 and spans up to level 80)
 * hard (甲) (Unlocks at HQ level 80 or above)
 * You can choose the difficulty in each map separately. However, you will not be able to jump from  Easy  to  Hard  immediately after clearing a map. To be able to use  Hard  setting, you must clear the previous map either on  Medium  or  Hard  itself. Only jumping above two difficulty levels is not allowed, for other combinations stick to the old rules.
 * 【 NOT POSSIBLE 】 Easy  >  Easy  >  Hard  (not possible because easy jumped to hard)
 * 【 POSSIBLE 】 Easy  >  Medium  >  Hard 
 * 【 POSSIBLE 】 Medium  >  Easy  >  Medium 
 * 【 POSSIBLE 】 Medium  >  Medium  >  Hard 
 * 【 POSSIBLE 】 Hard  >  Hard  >  Easy 
 * 【 POSSIBLE 】 Hard  >  Hard  >  Medium 
 * When the difficulty is changed, the boss's health bar will be reset.
 * 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 the difficulty used to clear it
 * Once the map is cleared, the enemy patterns revert back to prefinal patterns.
 * Different difficulties give different medals, equipment and materials when clearing the maps
 * As a general rule of thumb:
 * If you do not possess a single second-remodel ship, your difficulty selection should be Easy
 * If you have second-remodel ships but your Combined Fleet is weaker than a single sortied fleet because it cannot hit anything reliably, your difficulty selection should be Medium
 * If your Combined Fleet has better performance than a single fleet, your difficulty selection should be Hard
