This article aims to provide a rough guide to help you decide on what to spend screws on.

Because most improvement bonuses are "square-rooted", the first upgrade provides the largest relative gain per screw, therefore it is critical to get relevant important equipment to {{Star}}'''+1''' before working on others.

This article aims to provide a rough guide to help you decide on what to spend your screws on. Because of the way most improvement bonuses are square rooted, the first upgrade provides you with the largest gain. Therefore it is critical to get important equipment to <span style="color:#00cccc;">'''★+1'''</span> before working on others.

===The Breakpoint Myth===
 +
Breakpoints refer to points where upgrade bonuses reach whole numbers. These points are stressed because of the way the game rounds down the results of most formulas. The misconception is that a 1.99 bonus is just as good as a 1.00 bonus because of rounding. While there is a slight grain of truth to the myth, things get a little complex in practice. Due to how many multipliers and other bonuses are involved, trying to hit equipment upgrade breakpoints doesn't affect very much in the grand scheme of things.
 +
 
 +
The most important thing to do is to upgrade your equipment to certain critical points:
 +
* {{Star}}'''+1''' : Provides the biggest power increase (square-rooted only).
 +
* {{Star}}'''+6''' : The point when failures start to kick in and costs take a jump.
 +
* {{MaxStar}} : The final step to maximize upgrade bonuses.
 +

In most cases, it is statistically cheaper to either toggle or not the "guaranteed improvement".

''Please refer to [https://akashi-list.me/ Akashi-List] or [[Improvement]] for more details on the process.''

As expected, when the guaranteed cost is too high, not guaranteeing the upgrade is on average cheaper screw-wise, but this is not counting any potential equipment that may be lost and so may imply a higher screw cost.

===The Breakpoint Myth===
+
Guaranteeing worthiness per base upgrade screw cost can then be defined as followed:
 +
<tabber>
 +
|-|General rules=
 +
When upgrading any equipment, Devmats and Screw are consumed, and eventually one or several equipment and consumables.
 +
*Since obtaining Devmats is not an issue, their cost is simply ignored.
 +
*Since failing an upgrade does not consume any consumables, they are ignored.
 +
*For equipment consumed :
 +
**If they are craftable or relatively easy to obtain, their cost is negligible in front of any screw cost.
 +
**If the equipment consumed is a very rare one, then guaranteeing the upgrade should be evident.
 +
**If the equipment consumed is itself made via Akashi's upgrades, '''then its total screw cost must be added to the base screw costs used in later examples.

* Ideally you should have around 14 [[20.3cm(no.3) Twin Gun Mount]] but 8 is a good number to start off with. You can round out the numbers of 20.3cm guns with [[8inch Triple Gun Mount Mk.9]] and [[8inch Triple Gun Mount Mk.9 mod.2]] if you have them.

* The 35.6 and 41 prototypes are not the best battleship guns but they are cheap and useful across many different battleships. Upgrade about 4 each but you can lower their priority as you get other, better guns.

* You can effectively use a maximum of 9 [[12cm 30 Tube Rocket Launcher Kai 2]] at one time. You can get away with 2 to start off with.

* The [[Type 91 Anti-Aircraft Fire Director]] is currently the best thing to put in reinforcement expansions if you're not otherwise using lookouts for cut-in boosts or Rocket Kai Nis for airstrike immunity. It provides bonuses to firepower, torpedo and fleet AA.

* Start off with upgrading 4 Quad torpedoes then focus on Quintuples as you get them. You'll want at least 12 torpedoes.

* Upgrading the searchlight will decrease enemy CI chance and give bonus firepower. Important for night battle.

* You'll want to upgrade [[8inch Triple Gun Mount Mk.9]] into [[8inch Triple Gun Mount Mk.9 mod.2]] then max the latter. It is currently the most powerful cruiser gun and can be complemented with the 20.3n3 to get the night battle accuracy bonus. Try to match

* It is important that you max the [[Zero Fighter Type 52 Model C (601 Air Group)]] before conversion as it is the only way to obtain an upgraded Reppuu 601.

* The [[Zero Fighter Type 62 (Fighter-bomber/Iwai Squadron)]] is quite useful when you need to eke out that last bit of fighter power and maintain CVCI. As a bonus, it counts as a night battle plane and it has shootdown resistance.

* The [[Type 98 Recon Seaplane (Night Scout)]] is upgraded purely for the bonus LoS. You can ignore this recommendation if you feel you aren't struggling to hit LoS requirements.

* The [[Type 1 Fighter Hayabusa Model III A]] is currently the best interceptor outside of events or quests.It also doubles as the best common 6 Range LBAS Fighter. You'll want to upgrade enough to fill out your LBAS slots in order to meet base defense unlock requirements in events.

There is only one equipment with a base brut screw cost above 15 (the [[SK Radar]]), and as every equipment consuming expensive "Akashi exclusive" or rare equipment, the average screw cost is less important that the raw cost, meaning that guaranteeing the upgrade is always worth it

=Improvement Guide=
 +
Several rankings for equipment improvements. Do note that:
 +
*Many equipment possibly improbable are omitted, as they are either:
 +
**Already listed in one of the lists,
 +
**Are obtainable elsewhere for cheaper,
 +
**Are just not worth improving or upgrading.
 +
*Some equipment can be in several lists.
  
−
===Medium===
+
==Quests Improvements==
 +
Several [[Quests]] require specific equipment to be upgraded in order to be completed, while others simply allow the use of upgraded equipment for conversion.
  
−
* Much like the 12.7Ck2, the [[12.7cm Twin Mount Type-D Kai 2]] provides some nice fit bonuses to destroyers. Unlike the C-type, it doesn't work with Shiratsuyu and Asashio-classes.
+
===Quests Requirements===
−
* While the [[12.7cm Twin Mount Type-B Kai 4 (Wartime Modifications) + Anti-Aircraft Fire Director]] is better than the Akizuki 10cm, it is also rare and expensive. You should upgrade it when you get the chance.
+
Here is the list of equipment that required to be improved to complete some quests:
−
* Although weaker than the Akizuki 10cm and the 12.7Bk4, the [[12.7cm Twin Mount Type-A Kai 3 (Wartime Modifications) + Anti-Aircraft Fire Director]] is easier to obtain. They can be useful to fill out your destroyer gun lineup if you don't have enough of the two former ones.
+
*''All improvements are lost during conversions.
−
* The [[Type 3 Shell]] and [[Shipborne Model Type 4 20cm Anti-ground Rocket Launcher]] are both important anti-installation equipment. Ideally you should have a pair of each at their advanced versions.

* While the [[16in Triple Gun Mount Mk.7 + GFCS]], [[Prototype 51cm Twin Gun Mount]], and [[51cm Twin Gun Mount]] are great guns, the cost far outweighs the benefits. It would be a good idea to +1 them as a high priority though.
+
===Traps===
−
* You'll want to upgrade torpedo bombers into night bombers to complement your night fighters. Don't bother if you don't have enough night fighters.
+
Some quests allow the use of upgraded equipment for completion, but will not keep any of the current equipment improvements, and so should be cleared with unimproved equipment:
−
* Both the [[Zuiun Model 12 (634 Air Group)]] and [[Zuiun Kai Ni (634 Air Group)]] are currently the best seaplane bombers. Getting them to their skilled versions is a good idea. They have shootdown resistance and function like fighter/bombers.
 
−
* Getting the [[Prototype Keiun]] to it's jet fighter/bomber version will open up more options for you.
 
−
* Depth charges aren't really important to upgrade but do it if you need the extra ASW power.

==Collection Improvements==
 +
Some equipment are only obtainable via Akashi upgrades.
 +
*''The list can be found [[Equipment#Unbuildable Equipment|here]]
 +
*If completing the Kancodex is a personal goal, then crafting those equipment becomes a necessity in the long run.
 +
*Making all those equipment should NOT be a priority over the rest, as most are not very useful or even useless.
 +
*See below for when making those equipment overlap with advised improvements.
  
−
===Very Low===
+
==Upgrade Advices==
 +
Here is a list of improvements that have as a main goal to "'''upgrade'''" said equipment into a better one.
 +
*Do that certain upgrades can be done in chains, with part of the chain ranging from worse than the upgrade, equivalent to, or even better.
 +
*The advisedness is here ranked from the most at '''1''', to least at '''10'''.
 +
*The "Total Srew Cost" is given as an indication, but does not reflect "real" with [[#Screw Guaranteeing/Saving|guaranteeing savings]] and consumed equipment being great factors to take into account.
 +
*Several good equipment are not listed there as they can be obtained otherwise more cheaply, or because the upgrade is just not worth it.

* Upgrades on the [[OTO 152mm Triple Rapid Gun Mount]] can be useful if your ship girls are expected to fight under air denial or incapability.
+
==Improvement Advices==
−
* Upgrading the [[Type 0 Observation Seaplane]] is only necessary if you find that you're struggling to meet LoS requirements.
+
Here is a list of improvements that have as a main goal to "'''enhance'''" said equipment's [[stats]].
−
* You'll only want 1-2 autogyro/helicopters. Their main purpose is to allow [[Hyuuga|Hyuuga Kai Ni]] to OASW.
+
*In some cases, the equipment can be upgraded, but the upgrade is inferior to the improved base equipment,
−
* As with the T3DC, upgrading depth charges is not terribly important. The [[Type 2 Depth Charge]] benefits from having a small armor-piercing ability and the mortars can double up as anti-installation equipment.
+
*In some cases, the improved equipment only shows its best potential on certain ships, thanks to [[Visible Fit Bonuses]],
 +
*Some of the listed equipment below are obtained from [[#Upgrade Advices|above listed upgrades]],
 +
*Equipment being improved only for upgrade purposes are not listed there,
 +
*The improvements related to [[#Quests Improvements|Quests]] are not listed there, and should be done with the quests in mind.

Introduction

This article aims to provide a rough guide to help you decide on what to spend screws on. Because most improvement bonuses are "square-rooted", the first upgrade provides the largest relative gain per screw, therefore it is critical to get relevant important equipment to Improved+1 before working on others. Please refer to:

The Breakpoint Myth

Breakpoints refer to points where upgrade bonuses reach whole numbers. These points are stressed because of the way the game rounds down the results of most formulas. The misconception is that a 1.99 bonus is just as good as a 1.00 bonus because of rounding. While there is a slight grain of truth to the myth, things get a little complex in practice. Due to how many multipliers and other bonuses are involved, trying to hit equipment upgrade breakpoints doesn't affect very much in the grand scheme of things.

The most important thing to do is to upgrade your equipment to certain critical points:

  • Improved+1 : Provides the biggest power increase (square-rooted only).
  • Improved+6 : The point when failures start to kick in and costs take a jump.
  • Max-Improved : The final step to maximize upgrade bonuses.

Screw Guaranteeing/Saving

In most cases, it is statistically cheaper to either toggle or not the "guaranteed improvement".

Reminder :

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%

Average screw cost when not guaranteed, assuming Akashi is Kai and not counting any equipment cost:

Average costs.png

As expected, when the guaranteed cost is too high, not guaranteeing the upgrade is on average cheaper screw-wise, but this is not counting any potential equipment that may be lost and so may imply a higher screw cost.

Guaranteeing worthiness per base upgrade screw cost can then be defined as followed:

When upgrading any equipment, Devmats and Screw are consumed, and eventually one or several equipment and consumables.

  • Since obtaining Devmats is not an issue, their cost is simply ignored.
  • Since failing an upgrade does not consume any consumables, they are ignored.
  • For equipment consumed :
    • If they are craftable or relatively easy to obtain, their cost is negligible in front of any screw cost.
    • If the equipment consumed is a very rare one, then guaranteeing the upgrade should be evident.
    • If the equipment consumed is itself made via Akashi's upgrades, then its total screw cost must be added to the base screw costs used in later examples.

There is only one equipment with a base brut screw cost above 15 (the SK Radar), and as every equipment consuming expensive "Akashi exclusive" or rare equipment, the average screw cost is less important that the raw cost, meaning that guaranteeing the upgrade is always worth it

Improvement Guide

Several rankings for equipment improvements. Do note that:

  • Many equipment possibly improbable are omitted, as they are either:
    • Already listed in one of the lists,
    • Are obtainable elsewhere for cheaper,
    • Are just not worth improving or upgrading.
  • Some equipment can be in several lists.

Quests Improvements

Several Quests require specific equipment to be upgraded in order to be completed, while others simply allow the use of upgraded equipment for conversion.

Quests Requirements

Here is the list of equipment that required to be improved to complete some quests:

  • All improvements are lost during conversions.

Collection Improvements

Some equipment are only obtainable via Akashi upgrades.

  • The list can be found here
  • If completing the Kancodex is a personal goal, then crafting those equipment becomes a necessity in the long run.
  • Making all those equipment should NOT be a priority over the rest, as most are not very useful or even useless.
  • See below for when making those equipment overlap with advised improvements.

Upgrade Advices

Here is a list of improvements that have as a main goal to "upgrade" said equipment into a better one.

  • Do that certain upgrades can be done in chains, with part of the chain ranging from worse than the upgrade, equivalent to, or even better.
  • The advisedness is here ranked from the most at 1, to least at 10.
  • The "Total Srew Cost" is given as an indication, but does not reflect "real" with guaranteeing savings and consumed equipment being great factors to take into account.
  • Several good equipment are not listed there as they can be obtained otherwise more cheaply, or because the upgrade is just not worth it.
