Main Remodel (Menu) page

Modernization is used to increase the Stats of a given ship, namely, the firepower Firepower, torpedo Torpedo Attack, anti-air Anti-Air, armor Armor, HP Health, ASW Anti-Submarine Warfare, and Luck Luck. 1 to 5 other ship girls are required in order to perform a Modernization.

  • This page is about the Modernization mechanic. Please see Remodel_(Menu) for information about the UI.

How To Modernize

 
Modernization selection. Here Amatsukaze has only 1 star of modernisation.
 
The Failure box ("Penguin") shown for failled modernizations.
  1. Click the Select (選択) button in the empty modernization slot to bring up a list of non-locked ship girls sorted by level.
  2. Select a ship girl to be placed in a modernization slot.
  3. Stats that will be improved will turn blue and show the potential maximum improvement.
    • HP, ASW, and Luck will just display a blue up arrow.
  4. Once the selection is made, to modernize, click on either:
    1. The Modernization Start (after disarming)!! button (blue, left), to modernize while desaming and saving any equipment curently equipped on the consumed girls,
    2. The Modernization Start!! (合成開始!!) button (green, right), to modernize while also losing any equipment curently equipped on the consumed girls.
    • The buttons will be greyed out if the ship girl cannot be modernized any further with the curently used ships.
  • If the modernization fails, the "failure box" (penguin) will be displayed.

Overview

  • Modernization upgrades for firepower, torpedo, AA, and armor are reset upon remodeling.
    • HP, ASW, and luck modernization upgrades are carried over.
  • Equipment on a ship girl used for modernization will be lost.
    • Remember to remove valuable equipment before using a ship girl as modernization fodder.
  • Stats cannot be increased beyond certain caps.
    • For firepower, torpedo, AA, armor, and luck; it is dependent on the ship girl and its remodels. Please see the individual ship girl pages or Ship Maximum Status for the caps.
    • For HP, it is +2, and may be capped lower after marriage HP gains;
    • For ASW, it is +9 for ships with a base ASW stat, 0 otherwise.
  • Locking ship girls will prevent them from showing up as modernization fodder.

When a ship get modernized, its "modernization level" increases, being represented by stars from 1 to 5.

  • Once fully modernized in firepower, torpedo, AA, and armor, the "Max Modernized Star" will be displayed next to her level.

General Modernization

This applies to firepower  , torpedo  , anti-air  , and armor  . The formula for bonus stats from Modernization to these stats is:

Modernization Stat Formula
[math]\displaystyle{ \begin{align} \text{Stat}_\text{success} &= \text{Stat}_\text{input} + \lfloor \frac{\text{Stat}_\text{input} +1}{5} \rfloor \\ \text{Stat}_\text{failure} &= \lfloor 0.5 \times \left( \text{Stat}_\text{input} + \frac{\text{Stat}_\text{input} +2}{5} \right) \rfloor \end{align} }[/math]
With
  • [math]\displaystyle{ \text{Stat}_\text{input} }[/math] the stat increase displayed on the Modernization menu.
Notes
  • There is a fixed 50/50 chance of success/failure.
  • Success/failure is calculated independently per stat.
    • This means that it is possible for one stat to succeed and another to fail.
  • Successes are capped by the cap of the respective stat.
    • This can change the modernization efficiency listed below.
  • For maximum gains, it is better to spam multiple +5 modernizations.

Special Modernizations

When using certain ships, it is additionally possible to modernize HP  , ASW  , and Luck  .

Notes
  • It is unclear if using more than 2 DE is taken into account. If it is, the speculated working is:
    • Using 4 DE will count as 2 pairs,
    • Using 3 or 5 DE with count as 1 or 2 pairs, and a single ship.

Luck Modernization

Luck can be modernized either by using Maruyu or DEs. Remember that luck modernization is not reset on remodel.

Notes
  • Modernization success is guaranteed if using 5 Maruyu.
    • This is why it is very important to remodel her to Kai before using her as modernization fodder.
  • Maruyu is the easiest and most efficient method to modernize luck. It is highly advised to save DEs to modernize HP.

Maruyu

A base remodel Maruyu will provide +1.2 luck while her Kai remodel provides +1.6 luck. Refer to the chart below for Modernization results:

Coastal Defense (DE)

DE have a chance of granting +1 luck when used alone or in pairs.

  • For single DE:
[math]\displaystyle{ \text{LUCKmod}_\text{Rate}\text{%} = 29 + 0.8 \times \text{Lv} }[/math]
  • For DE pairs:
[math]\displaystyle{ \text{LUCKmod}_\text{Rate}\text{%} = 100 - \text{X}_\text{Rate}\text{%} }[/math]
With
  • [math]\displaystyle{ \text{Lv} }[/math] the level of the DE used in the modding,
  • [math]\displaystyle{ \text{X}_\text{Rate} }[/math] either the ASW or HP modding rate from the below formulas.

Notably:

  • +1 luck or HP is guaranteed from upgrades of pairs of different DE from a same class.
  • +1 luck or ASW is guaranteed from upgrades of single DE of any other pairing.
  • If the total level of 2 DE is around 80+ (e.g. each of them lv 40+), there is a small chance (~6-7%) for an extra +1 luck
    • In the case the ship cannot receive one of the 2 guaranteed stats (e.g. a BB for ASW) then there is a chance to fail the modernization.

Pumpkins

It is possible to use the Pumpkins given during the Pumpkin Festival to increase luck during regular modernization.

  • See here for more details.

ASW Modernization

ASW increase is capped at +9. Currently, DEs are the only way to modernize ASW.

  • Modernization is only possible for ships that already have some base ASW stats.
  • Modernization will fail if the ship girl is at the ASW cap.
    • Modernization can still succeed if luck is rolled instead of ASW (if the ship girl is not at her luck cap).

Using single or a pair of DE that are not different DE of a same class will guarantee +1 ASW or +1 Luck.

  • Using pairs of different DE from the same class will also guarantee +1 ASW or +1 Luck if the ship is already at max HP.
  • It has been observed that, the higher the total level of two DEs used for modernization, the higher is the chance to get +1 ASW.

The ASW mod success rate compared to the Luck mode is approximately as follows [1]:

  • For single DE:
[math]\displaystyle{ \text{ASWmod}_\text{Rate}\text{%} = 100 - \text{LUCKmod}_\text{Rate}\text{%} }[/math]
  • For DE pairs:
[math]\displaystyle{ \text{ASWmod}_\text{Rate}\text{%} = 10 + 0.40 \times \sum_\text{DE} \text{Lv} }[/math]
With
  • [math]\displaystyle{ \text{Lv} }[/math] the level of the DE used in the modding.
  • [math]\displaystyle{ \text{LUCKmod}_\text{Rate} }[/math] the luck modding rate from the above formula.
  • Notably :
    • If the total level of both DE is around 80+ (e.g. each of them lv 40+), the rate is about 20-30 %.
    • Using two DE pairs with a level total at 180+ has a chance of +2 ASW.

HP Modernization

HP can be increased by using DEs, Mizuho, or Kamoi. DEs must be used in pairs of two different ship girls from the same class to get +1 HP.

For unmarried ships, HP can always be increased by a maximum of 2 points. Exceptions for married ships are:


Using pairs of different DE from the same class will guarante +1 HP or +1 Luck.

  • If the ship is already at max HP, this will instead guarantee +1 ASW or +1 Luck.
  • It has been observed that, the higher the total level of two DEs used for modernization, the higher is the chance to get +1 HP.
  • The HP mod success rate compared to the Luck mode is approximately as follows [2]:
[math]\displaystyle{ \text{HPmod}_\text{Rate}\text{%} = 30 + 0.35 \times \sum_\text{DE} \text{Lv} }[/math]
With
  • [math]\displaystyle{ \text{Lv} }[/math] the level of the DE used in the modding.
  • Notably :
    • If both DE are Lv 1, the rate is about 30 %,
    • If the total level of both DE is around 180+ (e.g. each of them lv 90+), the rate is about 90% [3][4].


Mizuho and Kamoi (AV/AO) can be used to increase the HP of certain ships.

  • Mizuho: Mizuho and Kamoi.
  • Kamoi: Mizuho, Kamoi, Agano-class, and Yamato-class.
  • Kamoi and Mizuho are not interchangeable.
  • Mizuho or Kamoi must be used in pairs to trigger HP modding,
  • The HP mod success rate compared to the Luck mode is as follows :
[math]\displaystyle{ \text{HPmod}_\text{Rate}\text{%} = 30 \times \text{N}_\text{b} + 40 \times \text{N}_\text{K} }[/math]
With
  • [math]\displaystyle{ \text{N}_\text{b} }[/math] the number of AV/AO on base form,
  • [math]\displaystyle{ \text{N}_\text{K} }[/math] the number of AV/AO on Kai+ form.

Notably, if the success rate goes over 100%, a roll for a second HP increase is performed (e.g. 120% = 20% chance for +2HP).
