Improvements are upgrades to equipment that increase their performance or upgrade them to better versions. Improvements are done in Akashi's Improvement Arsenal, requiring Akashi. Improvement Materials Improvement material are notably used for improvements.

  • For a comprehensive list of improvements, please refer to Akashi-List or the List of Improvements.

Overview

  1. Improvement levels are displayed beside equipment names.
    • They run from Improved+1 to Max-Improved (+10).
  2. Improvement bonuses are hidden. The increase in stats is not reflected on ship girls' stat cards.
    • This means they do not count for Support Expeditions or for reaching certain thresholds like for OASW.
    • Those bonuses work to some extent to reach regular Expeditions thresholds.
    • Some improvements on equipment can add some additional visible Fit Bonuses.
  3. Equipped equipment cannot be improved.
    • There is an option to unequip the equipment from the improvement list.
  4. Equipment must be unlocked in order to be upgraded to a better version.
  5. Improvements have a chance to fail. Please see below.
    • Materials and any fodder equipment are still lost on failure.
    • The equipment being improved is never lost.
    • It is recommended to use the guaranteed improvement toggle when dealing with expensive improvements and/or rare fodder at Improved+6 and beyond.
    • Akashi Kai has a higher success rate than her base version.
  6. Improved equipment cannot be used as fodder.
  7. Certain conversion quests like F13, F14, F15, F19, F22, and F24 to F30, that do not require improved equipment, will carry over any Improved to the upgraded equipment.
  8. Certain conversion quests like F62, F89, F70, and F107, allow to use Improved equipment, but any Improved are lost during conversion.

Improvement Success Rates

Akashi's level does not affect improvement rates. However, her remodel status does. It is highly recommended that she be remodeled to Kai as soon as possible, to maximize improvement success rates. The data below is sourced from KanColle Kai.

Modification Level 1★ 2★ 3★ 4★ 5★ 6★ 7★ 8★ 9★ Max★ Upgrade
Akashi 100% 100% 100% 100% 95% 90% 80% 77% 72% 60% 50%
Akashi Kai 100% 100% 100% 100% 100% 95% 90% 82% 77% 67% 62%

Improvement Bonuses

The bonus stats gained from improvement will vary depending on the type of equipment as well as the stat itself.

  • Most improved stats will come as decimal numbers due to the use as base decimals and how square roots work.
  • It is important to note that decimals must not be discarded in favor of whole numbers, as stats will be multiplied by various formulas anyway, to finally be rounded down/up.
  • For calculated improvment bonuses, please refer to the Categories Charts or Reference Charts.

The improvement effects are unknown for:

  • Land-based Reconnaissance AircraftLB Land-Based ReconsType 2 Land-based Reconnaissance Aircraft
    Type 2 Land-based Reconnaissance Aircraft (Skilled)
    .
    • Air power and LoS might be affected, but it is unknown due to how LBAS work.
  • Submarine Equipment Submarine Equipment.
    • It is confirmed that it is none of the usual stats, probably nothing at all.
  • Ration RationsCombat Ration
    Combat Ration (Special Onigiri)
    Canned Saury
    .
    • It is confirmed that it is none of the usual stats, probably nothing at all.
    • Morale gains might be affected. So far, improvement serves to upgrade them into their improved versions.
    • Since improving a Combat RationCombat Ration up to +6★ cost 0 screw, it is possible to farm some screw by upgrading a ration once a day while doing quest F18.
  • Landing Forces Army Units (unmaped yet)

Square Rooted Bonus

Most bonuses are all a function of the square root of the improvement level. The bonus can be calculated by:

[math]\displaystyle{ \text{Bonus}_\text{stat} = \sum_{\text{All equips}} \text{Mod}_\text{equip} \sqrt{\bigstar} }[/math]

  • [math]\displaystyle{ \bigstar }[/math] is the improvement level of the equipment.
  • [math]\displaystyle{ \text{Mod}_\text{equip} }[/math] is the equipment modifier for that stat. Please refer to the table below for details.
