Damage Calculations
Damage Formula
[math]\displaystyle{ \text{Damage} = \left [ \left [ \left [ \text{Atk}_\text{cap} \times \text{Mod}_\text{post}\right]\times \text{Crit}\right]-\text{Armour}\right]\times \text{Ammo} }[/math]
- [math]\displaystyle{ \text{Atk}_\text{cap} }[/math] is the Cap Adjusted Attack Power
- [math]\displaystyle{ \text{Mod}_\text{post} }[/math] is any post-cap modifiers that are applicable.
- [math]\displaystyle{ \text{Crit} }[/math] is the critical strike modifier.
- [math]\displaystyle{ \text{Ammo} }[/math] is the remaining ammunition modifier.
- [math]\displaystyle{ \text{Armour} }[/math] is the armour of the target.
Where, Cap Adjusted Attack Power is Basic Attack Power that has been adjusted by applying the damage cap.
[math]\displaystyle{ \text{Atk}_\text{cap} = \text{Cap} + \sqrt{\left [ \text{Atk}_\text{basic} \times \text{Mod}_\text{pre}\right]-\text{Cap}} }[/math]
- [math]\displaystyle{ \text{Cap} }[/math] is the damage cap relevant to the phase.
- [math]\displaystyle{ \text{Atk}_\text{basic} }[/math] is the basic attack power of the relevant attack.
- [math]\displaystyle{ \text{Mod}_\text{pre} }[/math] is any pre-cap modifiers that are applicable.
Important Notes
- Pre- and post-cap multipliers are multiplicative.
- Results are rounded down to the nearest whole number. I.e. 4.2 → 4.
Basic Attack Power Formulas
The following formulas only apply to single fleets. Please see Combined Fleet, Land-Based Air Squadron and Support Expeditions for more details.
Important Notes
- Please see Akashi List for upgrade bonus values.
- [math]\displaystyle{ \text{FP} }[/math] is the firepower of the ship including equipment.
- [math]\displaystyle{ \text{TRP} }[/math] is the torpedo power of the ship including equipment or plane.
- [math]\displaystyle{ \text{ASW} }[/math] is the anti-submarine power of the ship or equipment.
- [math]\displaystyle{ \text{DB} }[/math] is the dive bombing power of the plane.
- [math]\displaystyle{ \bigstar }[/math] is the upgrade bonus of the equipment.
Bombing
This applies to both jet assaults and airstrikes.
[math]\displaystyle{ \text{Bombing Power} = \text{Type} \times \left[ \left[ \left[ \text{DB}\ OR\ \text{TRP} + \bigstar \right] \times \sqrt{\text{Count}_\text{Plane}}\right] + 25\right] }[/math]
- [math]\displaystyle{ \text{Type} }[/math] is a multiplier based on the type of the plane. See below for details.
- [math]\displaystyle{ \text{Count}_\text{Plane} }[/math] is the number of planes performing the attack.
| Type | Multiplier | Notes |
|---|---|---|
| Torpedo Bombers | 0.8x or 1.5x | The multiplier is chosen randomly. The chance is roughly 50%. |
| Dive Bombers Seaplane Bombers |
1.0x | |
| Jets (During jet assault) |
1.0x | |
| Jets (During normal bombing) |
0.7071x |
Important Notes
- Bombing power is calculated independently for each equipment slot on the carrier.
- The firepower of the carrier does not affect bombing 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, formation or damage states.
- It is affected by contact.
