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'''.
 
  
−
'''Please note that all formulas between <math>\lfloor \ \rfloor</math> or marked with <math>\downarrow</math> are [[wikipedia:Floor and ceiling functions|rounded down]].
 
−
 
−
* For example, <math>\lfloor 4.2 \rfloor = 4</math>.
 
−
* <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).
 
−
**<math>\times_\downarrow</math> is used when the round down applies only when the modifier is applied.

=Damage Formula=
 
−
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

=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}

−
** ''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 formulas according to the type of attack and the phase of battle
 
−
#'''Pre-cap
 
−
#*The basic attack goes 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

−
* <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.

===Carrier Shelling Attacks===

−
|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.

=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.

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.

===Scratch Damage===
 
−
In the following cases, attacks will deal '''"scratch damage"''' instead of normal ones:
 
−
*If a [[Cut-in]] or a [[special attack]] is evaded;
 
−
*The target's armor cannot be penetrated (attack inferior to eh enemy defense);
 
−
*The ammo count hits 0;
 
−
*When a single fleet attack submarine at night;
 
−
*When a [[Friendly Fleet]] attacks the last remaining ship of an enemy fleet.
 
−
 
−
Scratch damage is dealt as a percentage of remaining HP calculated using the following formula:

===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.

−

−

Overkill protection will take off between '''50-80% of the ship's current HP {{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.
