Construction

Construction Menu as shown

Large Ship Construction Menu as shown

Construction is accessible from the Arsenal menu and allows building new ship girls. Note that not all ships are available from construction, some being drops from normal maps, and others event exclusive (see below for details).

• For a more comprehensive list of construction recipes and rates, please see PoiDB's construction page.

Constructing a girl costs Resources. It will also take time unless instant constructions are used.

• Every player starts off with only 2 construction slots. Up to 2 more slots can be unlocked by using a Dock Opening Key each time.

Construction Types

Normal Construction

"Normal Construction" is the basic construction method. Recipes range from 30-999 fuel , ammo , steel and bauxite and each attempt costs 1 development material . Speeding up construction costs 1 instant construction .

• Construction results are solely determined by the amount of resources used.
  • The HQ level or the Secretary used do not affect the building result (except for Z1 & Z3).

If applicable, it is often more resource efficient to find a desired ship in sorties as a drop rather than building them.

Large Ship Construction

"Large Ship Construction" (LSC) allows to build rarer "bigger" ships in exchange for more resources. Recipes range from 1500-7000 fuel and ammo ; 2000-7000 steel and 1000-7000 bauxite . Each attempt also costs either 1, 20, or 100 development materials . Speeding up construction costs 10 instant construction .

• LSC is unlocked by completing quest F10.
• According to the developers, having empty construction docks very slightly increases the chances of obtaining rarer ships [1]. This statement has not been fully tested yet.

• Construction results are solely determined by the amount of resources and devmats used.
  • For few ships, an exact Secretary is required in order to be built, see below.

Special Secretary

Some ships require a specific Secretary (1st fleet flagship) in order to be crafted.

• For any other construction, the Secretary is independent of the crafting result.

Large Ship Construction Recipe

This section is outdated and needs updating. Some recipes and percentages are missing and outdated. Potential misinformation. Those recipes are still viable.

Using any of the above mentioned Helper is either required or discouraged, depending on the targeted craft.

• When crafting a ship requiring a helper, then said helper is mandatory,
• However, when crafting any other ship, using those helpers will decrease the crafting rate of the targeted ship.

Notes

• Regarding the use of 1/20/100 Devmats:
  • The amount used affects the pool of craftable ships, with some ships only appearing with 20+ Devmats.
  • Using 100 Devmats does give better rates for some heavier ships, but the gain is often too marginal to justify this cost increase.
  • E.g.:
    • I-401 chances are improved with 1 dev mat.
    • Yamato appears with all dev mat inputs.
    • Bismarck and Musashi do not appear with 1 dev mat.
    • Aiming for Bismarck before Musashi can help save both resources and Devmats as Musashi can always appear from a Bismarck attempt, but not necessarily the other way around (if a German ship is not used).

Sources

• Based on Poi-Statistics and UnlockACGWebPro reports.
• Kancolle DB reports include all development materials and Secretary used. This is especially noticeable for BB recipes where the number of attempts with/without Z1/Z3 skew the results towards either Bismarck or Yamato-class significantly. However, since the data sets are still significantly less biased than wikiwiki reports, it gives a better idea of what to expect.
