==Calculation==
The main goal of the game is to sink Abyssals. Abyssals are sunk by doing '''Damage''' to them. This page lists all the applicable formulas and mechanics that affect the calculation of '''Damage'''.  The formulas presented on this page are still subject to change as more testing is done.
+
Installations generally have a lot of HP and/or armor. But multiple different cumulative bonuses exist against them, allowing for massive damage when using the right set-ups.
 
+
These bonuses are divided into 5 groups and are calculated in the following order<ref>https://docs.google.com/document/d/1mXGyJ3yeNWeOmuGZQrXkcuGSuSEQYqmKhPelHMkzkGI/edit</ref>:
'''Please note that all formulas between <math>\lfloor \ \rfloor</math> or marked with <math>\downarrow</math> are [[wikipedia:Floor and ceiling functions|rounded down]].
+
# [[#Ship Type Bonuses|Ship type bonuses]],
 
+
# [[#General Multiplicative Bonuses|General multiplicative bonuses]],
* For example, <math>\lfloor 4.2 \rfloor = 4</math>.
+
# [[#Landing Craft Specific Bonuses|Landing craft specific bonuses]],
* <math>4.2 \times_\downarrow 1.5 = \lfloor 4.2 \times 1.5 \rfloor = \lfloor 6.3 \rfloor = 6</math>, '''but''' <math>4.2 \times_\downarrow 1 = 4.2</math> (by definition, <math>\times_\downarrow</math> is then a non-commutative non-associative operator, it is assumed to be left-associative with lower priority than the usual multiplication operator).
+
# [[#Flat Damage Bonuses|Flat damage bonuses]],
**<math>\times_\downarrow</math> is used when the round down applies only when the modifier is applied.
+
# [[#Post-Cap Bonuses|Post-cap bonuses]],
 
+
# [[#Airstrike And Land-Base Bonus|Airstrike and land-base]] special cases,
 
+
# [[#Installation-Like Warships|"Installation-like warships"]] special cases.
=Damage Formula=
+
*The bonuses' exact order is still under investigation and may be subject to changes.
The '''Damage''' is the reduction of '''HP''' {{HP}} caused by an attack hitting a target. The formula is the same for all attacks as well as abyssals. It stems from the difference between the final attack power of the assailant and the defense power of the target.
 
{{Formula
 
|Title=Damage Formula
 
|Math=\text{Damage} = \biggl \lfloor \biggl ( \text{Atk}_\text{post-cap}  - \text{DEF} \biggr ) \times \text{Ammo} \biggr \rfloor
 
|Var=<math>\text{Atk}_\text{post-cap}</math> the final attack power of the assailant after the cap and all the modifiers have been applied, described below,
 
* <math>\text{DEF}</math> the '''[[#Defense Power|defensive power]]''' of the target,
 
* <math>\text{Ammo}</math> the '''[[#Ammunition Modifier|remaining ammunition]]''' modifier.
 
}}
 
 
 
=Defense Power=
 
Defense power represents the ability of a ship to resist damage. It's calculated from the '''Armor''' {{Armor}} plus a random element.
 
 
 
{{Formula
 
|Title=Defence Formula
 
|Math=\text{DEF} = \left( \text{Armor} \times 0.7 + \text{Armor}_\text{rand} \times 0.6 \right) - \text{Pen}
 
|Var=<math>\text{Armor}</math> the armor {{Armor}} of the target including all equipment and upgrade bonuses,
 
* <math>\text{Armor}_\text{rand}</math> a random number between <math>0</math> and <math>\lfloor\text{Armor}\rfloor - 1</math>,
 
** Note that it is inclusive, meaning it can also output <math>0</math> and <math>\lfloor\text{Armor}\rfloor - 1</math>
 
* <math>\text{Pen}</math> any applicable armor penetration mechanic:
 
** ''See [[#Anti-Submarine Warfare|ASW]] for details on ASW armor penetration,
 
** Some [[#Debuffs|debuffs]] may include armor penetration.
 
|Notes=The range of armor values is uniformly distributed, every armor roll has the same chance of occurring.
 
}}
 
 
 
For short, defensive power randomly varies between '''1.3''' x{{Armor}} and '''0.7''' x{{Armor}}.
 
 
 
=Attacks Power=
 
 
 
Attack power represents the ability of a ship to inflict damage. It's affected by a lot of different elements (stats, mechanics, "battle state", etc.) through 4 steps of calcul:
 
#'''Basic
 
#*Generally calculated from the relevant stats of the ship using different formula according to the type of attack and the phase of battle
 
#'''Pre-cap
 
#*The basic attack go through different modifiers
 
#'''Cap
 
#* If the attack is superior to a cap it's reduced
 
#'''Post-cap
 
#*These modifiers are more potent because they are not limited by the cap

==Basic Attack Power Formulas==
 
The following section details the different formulas to calculate <math>\text{Atk}_\text{base}</math>. As the formula depends on the type of attacks and the combat phase.
 
 
 
Below are the common variables used in all accuracy formulas:
 
* <math>\text{FP}</math> is the '''Firepower''' {{Firepower}} of the ship including equipment.
 
* <math>\text{TP}</math> is the '''Torpedo''' {{Torpedo}} of the ship including equipment or the torpedo of a plane.
 
* <math>\text{ASW}</math> is the '''Anti-submarine''' {{ASW}} of the ship or equipment.
 
* <math>\text{DB}</math> is the '''Dive bombing''' {{Dive}} of the plane.
 
* <math>\bigstar</math> is the upgrade bonus of the equipment.
 
** See [[Improvement]] or [https://akashi-list.me/ Akashi List] for upgrade bonus values.
 
* <math>\text{Plane}_\text{Count}</math> is the remaining amount of planes in a slot, performing the attack.
 
* <math>\text{Mod}_\text{CF}</math> is the combined fleet modifier based on the tables below:

|Notes=Airstrike power is calculated independently for each equipment slot on the carrier.
 
* The firepower of the carrier does not affect airstrike power.
 
* The power is calculated '''after''' the air combat and anti-air fire phases which means bombers getting shot down will affect the final calculation.
 
* It is not affected by [[#Engagement|engagement]], [[#Formation|formation]] or [[#Damage State|damage states]].
 
* It is affected by [[#Aerial Contact|contact]].
 
This applies to [[Jet Assault]]s and [[Airstrike]]s.

===Surface Shelling===
 
{{Formula
 
|Title=Surface Attack Formula
 
|Math=\text{Atk}_\text{base shelling} = \text{FP} + \bigstar + \text{Mod}_\text{CF} + 5
 
|Notes=The caliber of the gun does not affect damage.
 
* Abyssal installations that are not equipped with a plane that has a torpedo or dive bombing stat will use the surface shelling formula for calculating damage.
 
This applies to most ships during the [[Combat/Day_Battle#Shelling_Phase|shelling phase]].
 
}}
 
 
 
===Carrier Shelling Attacks===
 
{{Formula
 
|Title=Carrier Shelling Attack Formula
 
|Math=\text{Atk}_\text{base carrier shelling} = \bigl\lfloor \left( \text{FP} + \text{TP} + \bigstar + \left[ \text{DB} \times 1.3 \right] + \text{Mod}_\text{CF} \right) \times 1.5 \bigr\rfloor + 55
 
|Notes=Dive and Torpedo groups contribute, respectively, 1.95 and 1.5 times their dive bomb and torpedo stats toward shelling power
 
* If a carrier is not equipped with any torpedo or dive bombers, she will not participate in shelling.
 
** This also applies if they have lost all bombers during the aerial combat phase.
 
** But even if an air group has had all its planes shot down, it will still contribute towards carrier shelling power (if the CV is still capable of attacking).
 
* Remember that there are potentially multiple sources of <math>\bigstar</math> bonuses.
 
* Slot sizes and the number of remaining aircraft '''do not affect''' carrier attack power during shelling.
 
* Carriers have the easiest time hitting the damage cap. This makes them very powerful assets for the fleet.
 
* Abyssal installations equipped with a plane that has a torpedo or dive bombing stat will use the carrier formula for determining shelling damage.
 
* Planes are '''not shot down''' when a carrier participates in shelling.
 
This applies to [[carrier]]s and {{Ship/Link|Hayasui Kai}}/{{Ship/Link|Yamashio Maru Kai}} during the [[Combat/Day_Battle#Shelling_Phase|shelling phase]].

|Var=
 
|Notes=Torpedoes cannot target submarines and Abyssal installations.
 
** If the only available targets are submarines, the attack will trigger but always miss.
 
**If the only available targets are installations, the attack will not trigger.
 
* A ship must have a base torpedo stat of more than 0 to perform torpedo attacks.
 
Torpedo Attacks only include the [[Opening Torpedo Salvo]] and [[Closing Torpedo Salvo]].

* [[Graf Zeppelin]], [[Saratoga|Base Saratoga]], {{Class|Taiyou|Kai Ni}}, [[Kaga Kai Ni Go]], and [[Ark Royal|Ark Royal (with Swordfish)]] use the surface night battle formula if they are not performing a carrier night attack.
 
* In night battle versus Abyssal installations, '''the torpedo stat is ignored'''.
 
** This also means any upgrade bonuses to torpedo power is ignored.
 
This applies to most ships during [[Night Battle]].

|Notes=Unlike daytime carrier attacks, it is possible to attack even if no bombers are equipped.
 
** Night fighters are still needed to trigger the attack.
 
* Like daytime carrier attacks, carriers are unable to attack if moderately damaged or worse.
 
** Armored carriers are only disabled at heavy damage.
 
** Carriers that can use the night battle shelling formula will use that instead if moderately damaged.
 
* The formula '''only takes into account the base stats of the carrier and night attack capable planes equipped'''.
 
** The [[Improvement]] stats are not taken into account.
 
*** This means any other stats and upgrade bonuses from equipment like guns and non-night-capable planes are ignored.
 
** This also means that any [[Visible Bonus]] from Planes is also ignored.
 
*** The [[Visible Bonus]]es given by the [[SDP+]] are whoever counted here.

===Anti-Installation Attacks===
 
{{details|Anti-Installation}}
 
Installations differ from regular enemy warships, as they are immune to certain attack elements like the torpedo stat, but are extremely weak against specialized gears.
 
 
 
==Support Expedition Attack Power Formula==
 
[[Support expedition]] attack formulas are close but not the same as combat formulas. They also are affected by fewer modifiers.
 
 
 
===Shelling Support===
 
Basic attack power is calculated in the same way as normal for surface ships and carriers except that firepower is reduced by 1.
 
 
 
===Airstrike Support===
 
{{Formula
 
|Title=Airstrike Support Attack Formula
 
|Math=\text{Airstrike Support} = \biggl\lfloor \biggl\{ \text{Type} \times \bigl( \left( \text{DB or TP} \right) \times \sqrt{\text{Count}_\text{Plane} } + 3 \bigr) \biggr\} \times \text{Mod}_\text{crit} \biggr\rfloor \times 1.35
 
|Notes=The [[Damage_Calculations#Damage_Formula|damage cap]] of 170 is applied to the result between <math>\{ \ \}</math>.
 
* <math>\text{Type}</math> is the bomber's type modifier, similar to airstrikes.

* The critical modifier and the 1.35x airstrike support modifier are both '''post-cap'''.

===Anti-Submarine Support===
 
{{Formula
 
|Title=Anti-Submarine Support Attack Formula
 
|Math=\text{ASW Support} = \biggl\lfloor \biggl\{ \bigl(\text{ASW} \times \sqrt{\text{Count}_\text{Plane} } + 3 \bigr) \times \left(0.9 + \text{Rand} \right) \biggr\} \times \text{Mod}_\text{crit} \biggr\rfloor \times 1.35
 
|Var=<math>\text{Rand}</math> a random number from 0 to 0.75 inclusive.
 
* The critical modifier and the 1.35x airstrike support modifier are both '''post-cap'''.
 
* The [[Damage_Calculations#Damage_Formula|damage cap]] of 170 is applied to the result between <math>\{ \ \}</math>.
 
|Notes=Because slot size matters, carriers make much better ASW support ships than light carriers.
 
* It has a chance of triggering at every node so consider the enemy compositions of all nodes when running ASW support to help with submarine nodes.
 
** A full ASW support setup that runs into enemy airpower will get destroyed.
 
* Because even the autogyros and liaison aircraft participate in aerial combat, they can be shot down.
 
* It can be useful for chipping down submarines to reduce the number of opening and closing torpedoes faced by the fleet.

=Attack Power Corrections=
 
 
 
After calculating the basic attack power of the attack being made, it is then adjusted based on various factors. Attack power modifiers can be split into pre- and post-cap modifiers. Post-cap modifiers are more powerful to have because they aren't reduced by the cap.

;Notes:
 +
*A {{LandingCraft}} [[Landing Craft]] might be required to be equipped on the attacking ship for this bonus to be applied.
 +
*As it is the only post-cap bonus common to all installations, it has a great potential.
 +
*Due to the limited nature of Rations, this bonus is mostly "Pay To Win", and so is not recommended.
  
===Airstrike Special Bonus===
+
===Airstrike And Land-Base Bonus===
 +
For the damage formula, please refer to the [[Land-Based Air Squadron#Attack Power|LBAS]] and [[Damage_Calculations#Airstrike|airstrike]] page. The multiplier is chosen randomly between two values. The chance is roughly 50%.
  
There's a bonus when attacking certain Princess and Demon-type enemies during airstrike. The multiplier is chosen randomly between two values. The chance is roughly 50%.
+
There are exceptions:
 +
*For {{BluePlane}} [[Torpedo Bomber]]:
 +
** The {{torpedo}} torpedo stat is counted as 0 in airstrike,
 +
** The behavior is unclear for LBAS (the damage are overestimated).
  
{|class="wikitable mw-collapsible"

Carriers get a bonus critical modifier when equipped with high proficiency planes. This modifier is multiplicative with the normal critical modifier.
 
 
 
* For '''Carrier Attacks''', they gain a '''1.2''' critical bonus multiplier for a {{Double Chevron}} plane in the top slot and an additional '''0.1''' for every other {{Double Chevron}} plane.
 
** For example, a carrier with two max proficiency planes (with one in the top slot) would get a critical bonus of: '''(1.2 + 0.1) x 1.5 = 1.95'''.
 
* For '''[[#Carrier_Cut-In_Attacks|Carrier Cut-In Attacks]]''', they gain a '''1.106''' bonus when a {{Double Chevron}} plane is selected to participate in the attack and an additional '''+0.15''' if one of the selected planes is in the top slot.
 
 
 
=Ammunition Modifier=
 
The damage of the fleet is reduced once their ammunition falls below 50%. This modifier '''cannot go above 1'''. The formula used to determine this is:

===Historical Bonus===
 
On almost every [[Event]] map, as well as some regular maps ([[7-4]] & [[7-5]] so far), certain ships, types of ships, equipment, or types of equipment will bring bonuses.
 
*Those bonuses are most of the time raw damage multipliers, and sometimes, accuracy bonuses.
 
*Bonuses are independent to each ship, so only the ships with any historical bonus or ships equipped with historical equipment will be affected.
 
*Bonuses may be applicable to some parts of a map only, such as specific phases of nodes.
 
 
 
This mechanic is here to encourage the use of "historically significant fleets and setups".
 
*By nature, historical bonuses are arbitrary, so refer to each individual map to see what bonuses are applicable.
 
 
 
===[[Debuffs]]===
 
Debuffs are a special case that only applies during events. Certain event maps have debuff mechanics that require meeting certain conditions to trigger them. Debuffs can be either a reduction to the enemy's armor or a post-cap damage modifier for the fleet.
 
 
 
'''Notes:'''
 
* Debuffs are affected by the remaining ammo modifier.
 
 
 
=Overkill Protection =
 
When a ship in the fleet takes more damage than her current HP, she will take a percentage of her current HP in damage instead.
 
* The ship must be the flagship OR
 
* The ship must not be {{color|red|'''heavily damaged (大破)'''}} nor {{color|red|'''red morale}}[[File:Battle Card Status Heavy Fatigue Face.png]] at the start of the battle.
 
** If the ship has red morale, she will just have her HP reduced to 1.
 
 
 
{{Formula
 
|Title=Overkill formula
 
|Math=\text{Damage}_\text{Overkill} = \text{HP}_\text{current} \times 0.5 + \text{HP}_\text{rand} \times 0.3

* <math>\text{HP}_\text{rand}</math> is a random HP number between 0 and <math>\text{HP}_\text{current} - 1</math>
 
|Notes=Therefore, the maximum damage from overkill protection is <math>\text{HP}_\text{current} \times 0.8 - 0.3</math> and the minimum damage is <math>\text{HP}_\text{current} \times 0.5</math>.
 
}}
 
 
 
Overkill protection will take off between '''50-80% of the ship's current HP'''.
 
 
 
'''Important Information'''
 
* In general:
 
** Overkill protection is most applicable to DDs.
 
*** The most pronounced effects of overkill protection occur at low HP
 
*** It is also the primary means of surviving a hit they fail to evade
 
*** For example, a 32HP DD has a 15.5% chance of being {{color|red|'''heavily damaged (大破)'''}} by a BB Hime, while a 31 HP DD has just a 6.5% chance
 
*** This has great implications when marrying ships, 36 HP has one of the highest chances of a taiha
 
** Odd-numbered HP is better when overkill protection is triggered. This is because the damage calculations round down, reducing the likelihood of being knocked down to heavy damage.
 
** This mechanism is most applicable to ships '''at full HP'''. Once a ship starts taking damage, the utility of overkill protection diminishes
 
* Generally ships with HP that are divisible by 4 have worse survivability.

Calculation

Installations generally have a lot of HP and/or armor. But multiple different cumulative bonuses exist against them, allowing for massive damage when using the right set-ups. These bonuses are divided into 5 groups and are calculated in the following order[1]:

  1. Ship type bonuses,
  2. General multiplicative bonuses,
  3. Landing craft specific bonuses,
  4. Flat damage bonuses,
  5. Post-cap bonuses,
  6. Airstrike and land-base special cases,
  7. "Installation-like warships" special cases.
  • The bonuses' exact order is still under investigation and may be subject to changes.

Notes
  • A Landing Craft Landing Craft might be required to be equipped on the attacking ship for this bonus to be applied.
  • As it is the only post-cap bonus common to all installations, it has a great potential.
  • Due to the limited nature of Rations, this bonus is mostly "Pay To Win", and so is not recommended.

Airstrike And Land-Base Bonus

For the damage formula, please refer to the LBAS and airstrike page. The multiplier is chosen randomly between two values. The chance is roughly 50%.

There are exceptions:

  • For Torpedo Bomber Torpedo Bomber:
    • The Torpedo Attack torpedo stat is counted as 0 in airstrike,
    • The behavior is unclear for LBAS (the damage are overestimated).
  • For JetFighterBomber2.pngJetFighterBomber1.png JetsKikka Kai
    Jet Keiun Kai
    :
    • There are inconsistencies with the bonuses.

Installation-Like Warships

This section is for special ships with installation-like behaviors, taking additional damage from anti-installation equipment.

  • Those bonuses are post-cap only, meaning none of the "anti-installation bonuses" previously mentioned are applied.
  • Be aware that the sample is limited (event only) so the information may be inaccurate and/or old[1].
