Improvement
Introduction
Improvements are upgrades to equipment that increase their performance or upgrade them to better versions. Akashi is required to improve equipment. Improvements are done in Akashi's Improvement Arsenal. Improvement Materials are needed for all improvements except Battle Ration 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 affect Support Expeditions or reaching thresholds like for OASW.
- 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 losed.
- It is highly recommended to use the guarateed 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).
- 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
For calculated improvment bonuses, please refer to the Reference Charts.
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.
