This article is a stub. You can help Kancolle Wiki by expanding it.

Notes

This system is made for Akashi and Akashi Kai. Now if you have her as your secretary ship, you will be able to use Akashi's Improvement Arsenal.(Tip: "Touch" the factory icon and wait for the Improvement factory icon to pop up - don't click on the factory icon)
To use this new factory, you need Improvement Materials. You can get them from Quest, or exchange them w/ medals (4 materials per medal), some new quests will have their reward as Improvement Materials.
You can also buy Improvement Materials from the in-game cash shop, the price is 700 DMM points for 10 Materials.
To improve your current equipment, you will need resources, development materials and Improvement Materials. The equipment that has been improved will have a ★ beside them. If the improvement level is low, then you will have a higher chance of success, and vice versa.
If you reach the maximum improvement level of your equipment, you can improve your equipment into a better, and a higher ranked one. However, your improvement level will be wiped once you do this. Also, if the new equipment after renewing is something you can develop from the normal factory, the improvement level will automatically be +3.
After you have reached +6 for any equipment improvement, you will have to spent a certain amount of unmodelled equipments that have the same type (name) in order to gain +7 up to +10 ★.
Tip from Official Twitter: For everyday in the week, the equipment you can improve will differ.
- And, when Akashi is at your first slot, certain ship girls in the second slot will bring changes to the equipment you can improve.
- More info: There's NO difference between a +0 equipment and a +10. But you can get a better equipment if you renew a +10 one.
- If you want to improve a equipment with a high improvement level, Akashi Kai has a higher success rate than Akashi herself.
