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 are notably used for improvements.
- For a comprehensive list of improvements, please refer to Akashi-List or the List of Improvements.
Overview
- Improvement levels are displayed beside equipment names.
- 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.
- Equipped equipment cannot be improved.
- There is an option to unequip the equipment from the improvement list.
- Equipment must be unlocked in order to be upgraded to a better version.
- Improvements have a chance to fail. Please see below.
- Materials and any fodder equipment are still lost on failure.
- Items are not lost.
- 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
+6 and beyond.
- Akashi Kai has a higher success rate than her base version.
- Materials and any fodder equipment are still lost on failure.
- Improved equipment cannot be used as fodder.
- Certain conversion quests like F13, F14, F15, F19, F22, and F24 to F30, that do not require improved equipment, will carry over any
to the upgraded equipment.
- This is currently the only way to obtain improved versions of the Tenzan Model 12 (Tomonaga Squadron)
, Suisei (Egusa Squadron)
& Reppuu (601 Air Group)
(unimprovable otherwise).
- This is currently the only way to obtain improved versions of the Tenzan Model 12 (Tomonaga Squadron)
- Certain conversion quests like F62, F89, F70, and F107, allow to use Improved equipment, but any
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.
- For calculated improvment bonuses, please refer to the Reference Charts.
The Minisub Midget Submarines
and
Rations
are the only equipment that do not gain any stats from improvement.
- Improving them only serves to upgrade them into their improved versions.
- Since improving a Combat 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.
Square Rooted Bonus
Bonuses to attack power (day shelling, night shelling, torpedo, ASW), anti-air, LoS, accuracy and evasion 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 modifer for that stat. Please refer to the table below for details.
Equipment Type | Day Battle | Night Battle | ASW | AA | LoS | Accuracy | Evasion | |||||
