Morale and Fatigue

Morale/Fatigue is a hidden statistic within the game. Each ship has their own morale value. It ranges from 0 to 100 and has various boosts and penalties associated with it.

↑ Morale = ↓ Fatigue

A high degree of fatigue can be seen as an actual lack of morale. Ships with enough rest will have a morale value of 49. A value above 50 is commonly known as the "Sparkle" effect.

Morale regenerates at 3 points every 3 minutes (like Fuel, Steel and Ammo) and this regeneration is capped at 49 points, where it will simply stop regenerating.

Indications

Below are the indications of your ship state. Specific effects will be explained below.

Morale value	Indication	Ship State
>50	The image of ship generates sparkling effect	High Morale
49~40	Ships are in their normal state.	Normal
39~30	Ship looks normal, but the "Mamiya Food Ship" button in Organize/編成 page is flashing.	Slightly Fatigued
29~20	An orange smiley face is shown by your ship image in the Organize/編成 page.	Moderately Fatigued
19~0	A red smiley face is shown by your ship image in the Organize/編成 page.	Seriously Fatigued

Effects

Morale value	Effects	Ship State
>50	[Sortie] Improved evasion during battle (Hidden, not shown on ship stats). Expedition] Higher chance (Not 100%) of getting Great success in expedition, which will yield a +50% resource gain increase. [Expedition] Higher chance of obtaining special items from expedition (eg. development materials/instant repair item. Only applicable for expeditions which actually give those). [Expedition] Higher chance of triggering Support Expedition #33 if the flagship is in high morale state.	High Morale
49~40	Normal state, no effect on performance/special effect.	Normal
39~30	[Sortie] Slightly decreased evasion and accuracy. [Expedition] Expedition will fail if your fleet returned in this fatigue state.	Slightly Fatigued
29~20	[Sortie] Generally decreased evasion and accuracy. [Expedition] Expedition will fail if your fleet returned in this fatigue state.	Moderately Fatigued
19~0	[Sortie] Severely decreases evasion and accuracy, almost every attacks will miss unless accuracy(命中)-increasing equipments were used. [Expedition] Expedition will fail if your fleet returned in this fatigue state.	Seriously Fatigued

Morale alone DOES NOT affect if your ships will sink or not, only the state of damage they are in when engaging (e.g, A ship with light/medium damage regardless of morale will always survive).  However, given the performance cut they get from fatigue, it is not advisable to take them to battle like that in general.

Fatigue has nothing to do with sinking. Tested and proven in many videos across the internet.

Morale modifiers

Below is a table of morale modifier in terms of morale value. +10 morale = -10 fatigue

Type	Action	Morale Modifier
Sortie/PVP	Obtaining MVP in a battle	+10
Sortie/PVP	As the flagship of a fleet	+3
Sortie/PVP	Enter a battle starting with night battle	+1
Sortie/PVP	Obtaining Battle Rank S/Perfect S	+1
Sortie/PVP	Obtaining Battle Rank A	±0
PVP	Fleet returns from PVP battle	±0
Sortie/PVP	Obtaining Battle Rank B	-1
Sortie/PVP	Obtaining Battle Rank C	-2
Sortie/PVP	Obtaining Battle Rank D/E	-3
Sortie/PVP	Enters night battle	-3
Sortie/PVP	Sortie with morale less than 30, regardless of obtaining any battle rank.	-6
Expedition	Fleet returns from normal expedition	-3
Expedition	Fleet returns from Support Expedition#33	-1~5
Expedition	Fleet returns from Support Expedition#34	-1~10
Sortie	Return from sortie	-15
Other	Newly constructed a ship	morale start at 40
Other	Ship obtained from sortie	morale start at 40
Other	Remodel a ship	removes all morale state, reset morale to 40
Other	Docking repair complete	reset to 40 only if morale is 0~39
Other	Using Mamiya Food Ship case 1	reset to 40 if morale is 0~39
	Using Mamiya Food Ship case 2	reset to 50 if morale is 0~49
Other	Morale natural regen	+3 morale per 3 minutes, until reaching 49.

It takes about 20 minutes to go from absolute zero to Orange and another 10 to go from Orange to normal.

Gaining morale with maximum efficiency and minimum cost

Running 1-1 solo

By doing a World 1-1 full run, your flagship will have a net morale gain of +13.

Assume that your flagship obtained S rank MVP in both nodes, and did not enter any night battle, it will be as follow:

New morale value

• = X +10 + 3 + 1 + 10 + 3 + 1 -15

• = X + 28 -15

• = X + 13

Just doing the first node will result in -1 morale, even if you perfect S rank it without a night battle.

(-15 + 13 + 1 = -1)

Day Battle S Victory in Exercises

By obtaining a battle rank S in PVP, and not entering night battle, your flagship will receive a net morale gain of +14, while your non-flagship ships(escorts) will receive a morale gain of +1.

New morale value for flagship

• = X +10 + 3 + 1
• = X + 14

Ships fully rested will have a morale of 49, by obtaining the +1 morale from battle rank S, their morale will become 50, which produces sparkle effect.

If the battle continued into the night battle, it will become

+1 -1 = ±0 for your escorts, which mean no morale gain.
