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]].
'''Please note that all formulas between <math>\lfloor \ \rfloor</math> or marked with <math>\downarrow</math> are [[wikipedia:Floor and ceiling functions|rounded down]].'''

=Damage Formula=
=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
|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.
|Notes=If <math>\text{Atk}_\text{post-cap}</math> is inferior to <math>\text{DEF}</math> or if <math>\text{Ammo}=0</math> then the attacks will deal "[[#Scratch Damage|scratch damage]]".
}}
=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=Defense 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,

** 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,
|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{Damage} = \biggl \lfloor \biggl ( \lfloor \text{Atk}_\text{cap} \rfloor \times \text{Mod}_\text{spotting} \times \text{Mod}_\text{CVCI} \times_\downarrow \text{Mod}_\text{AP} \times \text{Mod}_\text{post} \times_\downarrow \text{Crit} - \text{DEF} \biggr ) \times \text{Ammo} \biggr \rfloor </math>

|Notes=Dive and Torpedo groups contribute, respectively, 1.95 and 1.5 times their dive bomb and torpedo stats toward shelling power

===Scratch Damage===
===Scratch Damage===
If a special attack is evaded, the target's armor cannot be penetrated, or the ammo count hits 0; attacks will deal '''"scratch damage"''' instead, also called '''"chip damage"'''.
In the following cases, attacks will deal '''"scratch damage"''' instead of normal ones:
*Scratch damage is dealt as a percentage of remaining HP calculated using the following formula:
*If a [[Cut-in]] or a [[Special Attack|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:
* <math>\text{HP}_\text{current}</math> is the current HP of the target.
{|class="wikitable mw-collapsible mw-collapsed" width="100%"
* <math>\text{HP}_\text{rand}</math> is a random HP number between 0 and <math>\text{HP}_\text{current} - 1</math>

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.
