Akashi's Improvement Arsenal

From Kancolle Wiki
Jump to navigation Jump to search

Improvement is made accessible by having Akashi or Akashi Kai as your secretary.

Equipment can be improved here and sometimes upgraded into new, better equipment. Different equipment can be improved based on the day of the week and which ship you have in the second slot of your first fleet.

How to Enter

Kaishu koushou.png
  1. Set Akashi or Akashi Kai as your secretary (first ship of the first fleet).
  2. At the home screen, hover your cursor over the factory icon).
  3. The Improvement Arsenal icon will slide out from beneath it as shown.
  4. Move your cursor to that icon and click.


How to Use

  • Improvement materials Item Icon Improvement Material.png are the primary component for improvement. They can be obtained through the following means:
  1. Specific quests
  2. 4 improvement materials in exchange for a medal.
  3. The in-game cash shop, which sells them in packages of 10 for 700 DMM points.
  4. Event map clearance rewards and first-class medals, the latter of which yields 10.
  • The 2nd ship in your first fleet determines which upgrades are available.
  • Improvements can fail.
    • Your chance of failure rises with equipment improvement ranking.
    • Your success rate is higher when using a remodeled Akashi.
    • On failure, components used will disappear; however, the equipment being upgraded remains unchanged.
    • There is a slider that guaranteed success in exchange for an increase in required development and improvement materials.
  • Equipment that has been improved will have a ★. Improvement ranks range from ★+1 to ★+10. ★+10 appears as ★max.
  • All improvement attempts from ★+6 onward use up equipment (most of the time this is the same as the equipment being upgraded). This requirement is present on some equipment even from ★+0.
    • Locked and previously improved equipment cannot be used as improvement fodder.
    • As equipment is spent even on failure, you are recommended to use the success slider when improvements consume rare equipment.
  • There is no visible stat difference between improved and unimproved equipment.
    • Improvements on equipment have been shown to increase firepower, torpedo and ASW depending on the category of the equipment. They are also speculated to contribute to base attack power.
    • Preliminary results as of May 31, 2015 are:
      • 12.7cm Twin Gun Mount (firepower), 25mm Triple Autocannon (torpedo), Type 94 Depth Charge (ASW), etc:
        • ★+1~3: +1 bonus to firepower/torpedo/ASW
        • ★+4~8: +2 bonus to firepower/torpedo/ASW
        • ★+9~10: +3 bonus to firepower/torpedo/ASW
      • 35.6cm Twin Gun Mount, 41cm Twin Gun Mount, etc:
        • ★+1: +1 bonus to firepower
        • ★+2~4: +2 bonus to firepower
        • ★+5~7: +3 bonus to firepower
        • ★+8~10: +4 bonus to firepower
      • 61cm Quad (Oxygen) Torpedo, 61cm Quint (Oxygen) Torpedo, etc
        • ★+1~2: +1 bonus to torpedo
        • ★+3~6: +2 bonus to torpedo
        • ★+7~10: +3 bonus to torpedo
      • Type 94 Depth Charge, Type 3 SONAR, etc
        • ★+2~7: +1 bonus to non-ASW firepower
        • ★+8~10: +2 bonus to non-ASW firepower
      • Depth charges, sonars, fire directors, and searchlights increase shelling damage (Type 91 FD ★+10 shown to increase effective firepower by 3). Torpedoes and autocannons do not.
  • Autocannons improvements increases the damage for torpedo salvo. (Example: 25mm Triple Autocannon Mount ★+9 shown to increase effective torpedo by 3)
  • The damage increase is speculated to be the same formula as the 61cm Quad (Oxygen) Torpedo Mount.
  • The effective increase is speculated to be [math]\displaystyle{ \text {Effective Bonus} = \text {Equipment Type Modifier} \times \sqrt {\text {★ value}} }[/math]. Equipment Type Modifier is listed in the collapsed table (as it depends on situation).
  • Example 1: 12.6cm Twin Gun Mount ★+6 (2.449) and ★+7 (2.645) provides a total of +5 effective bonus.
  • Example 2: 35.6cm Twin Gun Mount ★+6 (3.674) and ★+5 (3.354) provides a total of +7 effective bonus.
  • ASW equipment bonus are applied not to the equipment bonus nor the base ASW value, but instead for damage calculation.
  • The bonus is not applied to support shelling fire.
Bonus Details

Medium Caliber Gun

(Note: ★+5 shown to give +2 bonus, but +3 bonus not confirmed yet)

  • If the equipment reaches the maximum improvement level (★max), it can sometimes be upgraded into stronger equipment. Be aware that the equipment's improvement level will reset, and a ★+10 equipment could be stronger than its unimproved upgrade.
    • If the new equipment after upgrading is something you can develop from conventional development, the improvement level will be automatically set to ★+3 (or ★+5 in a few cases).
    • This has a higher chance of failure than normal improvement.

Possible Improvements

Equipment that can be improved depends on the day of the week and the ship in the second slot of the first fleet. Changes at 0:00 JST.

When the 2nd Ship varies by day, the ship's initial is used; '✓' denotes that any ship listed may be used.

A ship named can do the improvement regardless of remodel level unless specified.
