Difficulty Selection

Each map in this event has four (4) difficulty levels (a.k.a. operation ranks) the player can choose from:

• Casual (丁) (Unlocks at HQ level 1)
• Easy (丙) (Unlocks at HQ level 1)
• Medium/Normal (乙) (Unlocks at HQ level 35)
• Hard (甲) (Unlocks at HQ level 80)

The operation rank affects enemy patterns, boss health and strength, the number of times the player has to sink the boss in order to clear the map and the drop rates of ships. Different ranks reward different medals, pieces of equipment and/or materials upon clearing a map. The higher the operation rank, the better the reward.

However, new ship rewards are available on all difficulty levels, and you only have to clear the final event map on Hard to get the exclusive First-class medal.

Click that option circled in as shown in red to change difficulty

You can choose the difficulty level for each individual map separately. However, you will NOT be able to select Hard for a map if you cleared the previous map on Casual/Easy. You must clear the previous map at least on Medium/Normal.

• 【NOT POSSIBLE】Casual/Easy > Hard
• 【POSSIBLE】(Medium/Normal)/Hard > Hard
• 【POSSIBLE】Casual/Easy/(Medium/Normal)/Hard > (Medium/Normal)
• 【POSSIBLE】Casual/Easy/(Medium/Normal)/Hard > Casual/Easy

Un-highlighted words indicate Current Difficulty

It is also possible to change the difficulty level afterwards, however:

• If you drop to a lower difficulty (e.g. from Hard to Normal/Easy), the current HP/TP bar value (the one you have the moment you drop down) will increase by 25% of the new maximum and you will retain ALL unlocking/phases done on the previous difficulty level.
• However, if you change to a higher difficulty (e.g. from Easy to Hard), the boss's HP/TP bar will be reset upon doing so and ALL unlocking/debuffs/phases will be reset as well. In short, you will lose your entire map progress!

Once the map is cleared (boss HP bar is depleted, boss is defeated, and the HP bar is no longer visible in the map):

• You CAN NO LONGER re-adjust the difficulty level, but can still farm the map on the difficulty you have chosen to clear the map with.
• The enemy patterns revert back to pre-final patterns.

Ship Locking

Introduced in the Summer 2014 Event, this mechanic locks ships that were sortied out to specific event maps, making them unable to participate in other ship-locked maps.

Example image from Winter 2019 Event

A ship girl will receive her ship lock as soon as she sorties to an event map with shiplocks. Afterwards, it's impossible to remove the lock until the end of the event. Remodeling or marrying a ship will NOT remove the shiplock, so be careful with who you sortie to event maps. However, locks are applied on a ship ID basis, meaning that duplicates of the same ship will not have the lock applied to them.

It is important to note that while shiplocks are applied regardless of the difficulty one chooses, they are generally only enforced on Medium and Hard difficulty. Outside of some event-specific branching rules, players on Casual and Easy difficulty are free to sortie ships with shiplock tags to any event map, regardless of the lock a map requires. However, as said before, ships will always be given a shiplock tag upon sortieing to an event map, and said tag cannot be overriden or removed via any means, so sortieing to event maps on lower difficulties will still lock ships out of event maps on higher difficulties. Always be careful about who is sortied to an event map.

Here's a shiplocking example using the Winter 2019 Event:

• Sortieing Murasame Kai Ni to E-1 will give her a grey shiplock tag. She is now only able to sortie to E-1 and no other event maps.
• Sortieing Sendai Kai Ni to E-2 in a single fleet will give her a green shiplock tag. She is now only able to sortie to E-2, and only in a single fleet composed of untagged or other green-tagged ships.
• Sortieing Jintsuu Kai Ni to E-2 in a combined fleet will give her a blue shiplock tag. She is now only able to sortie to E-2, and only in a combined fleet composed of untagged or other blue-tagged ships.
• Sortieing Isokaze B Kai to E-3 will give her a yellow shiplock tag. She is now only able to sortie to E-3 and no other event maps. Although you can use both a single and combined fleet in E-3, unlike in E-2 they both use the same yellow shiplock tag, so you can sortie Isokaze in either a single or combined fleet with no issues.

The number and scope of shiplocks varies from event to event, so checking the current event page for lock information before starting is always a good idea. This is also a reason to keep multiple ships per ship-type prepared. If you lack in certain ship-types, you may not be able to fulfill branching routes on later maps, or may be forced to use a sub-optimal composition.

Support expeditions do not check for ship locks, with the exception of the Summer 2014 Event.

HP/TP Bar Scaling
The amount of HP (or TP) required to clear a map usually varies depending on an Admiral's HQ Level (this was first observed during Summer 2015 Event). The higher the HQ Level is, the more kills (or TP) may be required to complete a map.
