===Scratch Damage===
===Scratch Damage===
If a [[Cut-in]] or 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 one:
*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 subamrine at night;
*When a [[Friendly Fleet]] attack the last reamining ship of an enemy fleet.
Scratch damage is dealt as a percentage of remaining HP calculated using the following formula:
{|class="wikitable mw-collapsible mw-collapsed" width="100%"
{|class="wikitable mw-collapsible mw-collapsed" width="100%"

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