Dropping ships from combat nodes in sorties is the main way to obtain new girls in the game, with a majority of "good" ships being only obtainable this way.

Overview

When scorring a victory on certain combat nodes, depending on the situation, a ship might be dropped and added to the enventory.

• Ship drops are always level 1 and on base remodel and modernization.

Drops depend on:

• The victory type, with "Victories" (S, A, and B ranks) being the only way to drop a ship.
  • Scorring an higger victory will usually yeld more and better drops.
• The node, with:
  • Most nodes droping ships on higher ranks only (mostly "A and S only", or even "S only"),
  • Some nodes not droping ship in any situation (mostly minor event nodes),
  • Boss node always dropping ships (only applicable to the final boss on most multi-boss maps),
• The current amount of ships posseed, with this only being relevant when riching the maximum ship capacity, preventing any drop,
• The dificulty (event only) changing the drop pool, with better drops being limited in higher difficulties.
• The drop pool, with for each node where it is possible to drop ships, drops are selected from a predetermined list:
  • The drop tables of each maps are listed here on the wiki, as well as on each individual map pages and ship pages, please refer to those tables for each situation.
  • As said, the pool is notably affected by the Victory type ans the event dificulty.
  • For a given drop pool, each dropppable ship will have a given drop rate,
  • Some pool will have a certain chance of droppping nothing,
  • Some individual drop rates might also be affected by drop caps, proportinaly increasing the rest of the drop rates of the list.

• The drop caps (only applicable for few ships), with some "rarer/more valuable" ships are limited in who many copies can be owned at once ("dupe cap") or on how many can be droped in a certain period of time ("overfishing cap"). This way, the majority of ships can be dropped an infinit amount of time (certain players have 200+ copies of a ship), but certain ships will have an arbitrary limit:

• • Unikely, for Akashi on 1-5 and 3-5, and Ooyodo on 1-6, they will drop only if currently not possessed, meaning that duplicates cannot be dropped here (dupes are still possible on any other location).

• • For the "dupe cap", on many can be owned at once, with their drop rate falling to zero on all locations when this cap is reached.
    • Usually, the amount of a given ship being possesed will affect the drop rate, the more ships the worse the rate, down to 0 %.
    • As this mechanic is not fully understand and is not very limiting, there is no clear list of the affect ships.
    • Famously, for the first few events after their introduction, Intrepid, Nelson, and Atlanta were each limited to only 1, meaning that it was impossible to drop duplicates. As of 2024-06-27 update, those limitations have been raised to at least 3.

• • For the "overfishing cap", so far only observed for Kaiboukans, there is a limit on how many

TLDR:

• There was a hard reset of drop pool of 7-4 on 11/2/2023, this caused the penalty to be gone (known as replacement drop penalty in the note com link) and allow player to drop DE again.
• Then if you own 3 or more of that same DE, the drop rate starts going down -> ideally keep only 2 copies at best to keep the rate high
• Then, if you feed away, sink or scrap that DE, you add +1 to **cumulative** counter

• If this **cumulative** counter hit 10+, it will be the earliest possible point that drop rate will also start going down, **regardless of how many copy you own**
• If its 14+ or more, the rate will definitely go down, same like above.

• The **cumulative** drop penalty may not cause it to drop all the way to 0% (as seen with 19 **cumulative** matsuwa in mirai tweet), but its really low, like maybe 0.18% or so

The drop condistion will NOT depend on:

• Items drops (e.g. Saury), were it is possible to drop both a ship and an items when applicable, the two being indepedent.
• The fact that a ship was scrapped rectly.
  • Certain rumors pretend that scrapping given ships will prevent said ships from dropping for a long time, but so far this was never veriffied, being additionnnally and odd arbitrary mechanic by itself.
• Some "mercy mechanic", improving the odds of dropping something after a given amont of attempts.

Limited Time Drops

A list of all the limited drops available on regular maps.

• Note that some limited drops might last for some weeks only, and others for several years, the duration of which being arbitrary.
• Most drops on 7-4 and 7-5 are very more likely permanent ones, but are listed there as devs where criptic about those drop being permanent or not.
