Accuracy, Evasion and Criticals

Accuracy, Evasion, and Criticals are three mechanics intertwined together, representing the ability of a ship to hit another one. The formulas presented on this page are still subject to change as more testing is done.

• Please note that all formulas between [math]\displaystyle{ \lfloor \ \rfloor }[/math] are rounded down.

Hit Rate

The hit rate is the probability of an attack hitting the target. It's the same for all attacks as well as abyssals. It stems from the difference between the Accuracy of the attack and the evasion of the target.

Hit Rate

[math]\displaystyle{ \text{Hit %} = \bigl\lfloor \text{Hit}_\text{cap} \bigr\rfloor + \text{Acc}_\text{proficiency} +1 }[/math] Where, the Capped Hit Rate [math]\displaystyle{ \left( \text{Hit}_\text{cap} \right) }[/math] is: [math]\displaystyle{ \text{Hit}_\text{cap} = \text{cap}_\text{max}\left( \text{cap}_\text{min} \left(\text{Accuracy}_\text{atk} - \text{Evasion}_\text{post-cap}\right) \times \text{Morale}_\text{defender} \right) }[/math] [math]\displaystyle{ \text{Accuracy}_\text{atk} }[/math] is the calculated accuracy of the attack. Please see below for the various accuracy formulas. [math]\displaystyle{ \text{Evasion}_\text{post-cap} }[/math] is the calculated evasion of the defending ship. Please see below for the evasion formula. If negative, it is still applied the same way, increasing the hit rate. [math]\displaystyle{ \text{Morale}_\text{defender} }[/math] is the morale state modifier of the defending ship. Morale is referring to the value of attacking timing, not the value before entering battle. Please see Morale and Fatigue for more details. Sparkled is 0.7, Normal is 1.0, Orange is 1.2, Red is 1.4. [math]\displaystyle{ \text{Acc}_\text{proficiency} }[/math] is the average plane proficiency accuracy bonus. Please see Plane Proficiency for more details. The average is calculated only from dive bombers, torpedo bombers, seaplane bombers and large flying boats. The value is 12 for ❱❱ planes. Hit Rate Caps There is a minimum and maximum hit rate in the game. The minimum of [math]\displaystyle{ \text{cap}_\text{min}\left(x\right) }[/math] is 10. The maximum of [math]\displaystyle{ \text{cap}_\text{max}\left(x\right) }[/math] is 96.

Notes:

• Hit rate has an effective minimum of 11% and a maximum of 97%.
• Plane proficiency is the only factor that allows a ship to go beyond 100% hit rate.
• The effect of sparkle is reduced the closer Hit rate is to the caps.

Critical Hit Rate

Critical Hits are hits that do more damage than normal. The critical hit rate stems directly from hit rate with different proportion depending on the attack type.

Critical Rate

[math]\displaystyle{ {Crit}_\text{rate} = \lfloor \text{Mod}_\text{type} \times \sqrt{\text{Hit}_\text{cap} + \text{Acc}_\text{proficiency}} \rfloor + \text{Crit}_\text{proficiency} + 1 }[/math] With: [math]\displaystyle{ {Mod}_\text{type} }[/math] the attack type modifier : [math]\displaystyle{ {Mod}_\text{type} }[/math] Attack type Attack modifier Shelling 1.3 ASW Torpedo 1.5 Airstrike 0 Night Battle [math]\displaystyle{ 1.5 + \text{Const}_\text{contact} }[/math] Shelling Support 1.0 Airstrike Support 0.2 [math]\displaystyle{ \text{Const}_\text{contact} }[/math] the night contact constant from Night Recons , its value depends on the stat of the if night contact is triggered, and 0 otherwise, [math]\displaystyle{ \text{Const}_\text{contact} }[/math] Contact constant 1 0.07 2 0.14 [math]\displaystyle{ \text{Hit}_\text{cap} }[/math] the Hit Rate Cap defined above, [math]\displaystyle{ \text{Acc}_\text{proficiency} }[/math] is the average plane proficiency accuracy bonus. Please see Plane Proficiency for more details. The average is calculated only from dive bombers, torpedo bombers, seaplane bombers and large flying boats. The value is 12 for ❱❱ planes. [math]\displaystyle{ \text{Crit}_\text{proficiency} }[/math] the plane proficiency critical bonus. See here for more details.

Hit Rate & Critical Roll

There is a single roll for both normal and critical hits.

For example, for a hit rate of 50% on a shelling attack, the crit rate is then 10%. The roll can be represented as followed:

Roll Example
Critical Hit 10%	Hit 40%	Miss 50%

The normal hit rate is 40% and the remaining 10% is the critical hit rate.

Notes

• The effect of accuracy and sparkling on crit rate is limited
• Because it stems directly from hit rate, it is also affected by the caps.
• With low accuracy, a disproportionately high amount of successful hits will be "criticals".
• With proficiency bonus it's possible to have a crititical rate above the hit rate, in this case the critical rate override the hit rate.[1]

Damage Animations

When a ship takes a hit, the game will display the damage animation following in 3 possible outcomes (e.g. with 25 damage):

• miss (no damage),
• 25 (normal damage)
• 25 Critical hit! (critical damage).

However, the damage status displayed is mostly defined by the amount of damage dealt, and not the real damage status happening in the game.

• Due to this, displayed critical hits and misses are rarely true critical hits or misses.

The displayed damage status is as follows:

Display Behavior
Damage Dealt	Damage Displayed
Miss	Miss displayed normally
0	Always displayed as a miss
≤14	Never displayed as Critical hit!
[15;39]	Criticals displayed normally
≥40	Always displayed as Critical hit!

Notes

• A patch exists to fix this misleading behavior and display the real damage status, see here.

Accuracy

Below are the common variables used in all accuracy formulas:

• [math]\displaystyle{ \text{Level} }[/math] is the level of the attacking ship.
• [math]\displaystyle{ \text{Luck} }[/math] is the luck of the attacking ship.
• [math]\displaystyle{ \text{Acc}_\text{equip} = \text{Acc}_\text{equip base} + \text{Acc}_\text{equip bonus} + \text{Acc}_\bigstar }[/math] is the total accuracy provided by an equipment, with:
  • [math]\displaystyle{ \text{Acc}_\text{equip base} }[/math] is the base accuracy of the equipment,
  • [math]\displaystyle{ \text{Acc}_\text{equip bonus} }[/math] is the visible accuracy bonuses,
    • Confirmed included for Day Shelling, excluded for Support Shelling, other phases unconfirmed
  • [math]\displaystyle{ \text{Acc}_\bigstar }[/math] is the equipment's accuracy gained from Improvement,
• [math]\displaystyle{ \text{Mod}_\text{fit} }[/math] is the Hidden Fit Bonuses bonuses or penalties when applicable.
• [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] is the formation modifier for the applicable attack. See Combat for more details.
  • Modifiers for single fleet against combined fleet are unknown.

• [math]\displaystyle{ \text{Mod}_\text{vanguard} }[/math] is an accuracy malus when the opposite fleet is in Vanguard formation. See below for more details.
  • It is still unknown if this affects night battles, airstrikes, ASW, or LBAS.

• [math]\displaystyle{ \text{Mod}_\text{morale} }[/math] is the morale modifier of the attacking ship. Morale is referring to the value of attacking timing, not the value before entering battle. See Morale and Fatigue for more details.

[math]\displaystyle{ \text{Mod}_\text{morale} }[/math]
Sparkled	1.2
Normal	1.0
Orange	0.8
Red	0.5

Notes

• Because of the number of modifiers to accuracy in-game, it is not trivial to increase accuracy. Therefore it is more important to prioritize attack power (firepower, torpedo, ASW, airstrike, LBAS, ...).

Combat

In no particular order.

Daytime Shelling

This formula applies to both surface shelling and carrier attacks during daytime combat. It does not apply to carrier airstrikes. [math]\displaystyle{ \text{Accuracy}_\text{shelling} = \bigg\lfloor \bigg( \Big( \text{Acc}_\text{base} + 2 \times \sqrt{\text{Level}} + 1.5 \times \sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip} \Big) \times \text{Mod}_\text{vanguard} \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} + \text{Mod}_\text{fit} \bigg) \times \text{Mod}_\text{spotting} \times \text{Mod}_\text{AP} \bigg\rfloor }[/math] With: [math]\displaystyle{ \text{Acc}_\text{base} }[/math] the base accuracy value of the attack.

This is because the other set-ups will interfere with artillery spotting and cost you better attack bonuses. The bonus only applies against BB, FBB, BBV, CA, CAV, CV, CVB. This include Installations. This means that this bonus does not apply against CL, CLT, DD, CVL, and AV.

Shelling Support

This formula applies to surface shelling and carrier attacks during shelling support. [math]\displaystyle{ \text{Accuracy}_\text{shelling support} = \bigg\lfloor \Big( 64 + 2 \times \sqrt{\text{Level}} + 1.5 \times \sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip base} \Big) \times \text{Mod}_\text{vanguard} \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} \bigg\rfloor }[/math] [math]\displaystyle{ \text{Acc}_\text{equip base} }[/math] does not include any Visible Bonus nor Improvement. [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] uses the same Day Shelling formation modifier as the sortieing fleet if Single vs Single combat, or 1.0 if the player fleet is Combined Vanguard uses Top value (0.8) only, vs DD exception also applies Player Single vs Enemy Combined is unconfirmed, but suspected to be 1.0 for all formations in line with Damage calculations

Torpedo Attacks

This formula only applies to opening and closing torpedo attacks during day battles. [math]\displaystyle{ \text{Accuracy}_\text{torpedo} = \left( \text{Acc}_\text{base} + 2 \times \sqrt{\text{Level}} + 1.5 \times \sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip} + \left \lfloor{\frac{\text{Attack}_\text{torp}}{5}} \right \rfloor + \text{Mod}_\text{ship} \right) \times \text{Mod}_\text{vanguard} \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} }[/math] With: [math]\displaystyle{ \text{Acc}_\text{base} }[/math] the base accuracy value of the attack.

[math]\displaystyle{ \text{Mod}_\text{ship} }[/math] the innate torpedo accuracy of the ship. Currently, only Abyssal ships have values above 0 ([2]).

Aerial Combat

This formula applies to the airstrikes performed during the aerial combat phase and support. Although ASW support functions like an airstrike for damage, it does not use this formula. [math]\displaystyle{ \text{Accuracy}_\text{airstrike} = \text{Acc}_\text{base} }[/math] [math]\displaystyle{ \text{Acc}_\text{base} }[/math] the base accuracy value of the attack.

Anti-Submarine Warfare

This formula applies to all ASW attacks in the combat phase and support. [math]\displaystyle{ \text{Accuracy}_\text{ASW} = \left( 80 + 2 \times \sqrt{\text{Level}} + 1.5 \times \sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\bigstar + 2 \times \sum \text{ASW}_\text{sonar} \right) \times \text{Mod}_\text{vanguard}? \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} \times \text{Mod}_\text{synergy} }[/math] With: [math]\displaystyle{ \text{Acc}_\bigstar }[/math] the "ASW accuracy" given from Improvement ( Sonar only) [math]\displaystyle{ \text{ASW}_\text{sonar} }[/math] the base ASW stat of any Small Small Sonars equipped. Large Large Sonars are not counted for this bonus. This modifier doesn't apply to the New Submarine Princess Flagship III [math]\displaystyle{ \text{Mod}_\text{synergy} }[/math] the synergy bonus from equipping certain combinations of ASW equipment. Synergy bonus is either currently bugged or so small it cannot be tested. Notes The base accuracy stat of the equipment is not included here. Equipping more sonars is the best way to boost ASW accuracy.

Night Battles

This formula applies to all night battle attacks. [math]\displaystyle{ \text{Accuracy}_\text{NB} = \bigg( \text{Mod}_\text{contact} \times \Big( 69 + \text{Mod}_\text{star shell} \Big) + 2 \times \sqrt{\text{Level}} + 1.5 \times \sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip} \bigg) \times \text{Mod}_\text{vanguard}? \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} \times \text{Mod}_\text{special} + \text{Mod}_\text{searchlight} + \text{Mod}_\text{fit} }[/math] With: [math]\displaystyle{ \text{Mod}_\text{contact} }[/math] the modifier of the Night contact, its value depends on the stat of the Night Recon .

Land-Based Air Squadron

This formula applies to attacks made by Land-Based Air Squadrons. The accuracy is calculated independently per squadron.

LBAS

This formula is still under investigation, results are not yet consistant with in-game test. [math]\displaystyle{ \text{Accuracy}_\text{LBAS} = \left( ( {\text{Acc}_\text{equip}} + \text{Acc}_\text{Sp} ) \times 7 + 95 \right) \times \text{Mod}_\text{vanguard}? \times \text{Mod}_\text{morale} \times \text{Mod}_\text{CF} + \text{Acc}_\text{proficiency} }[/math] With: [math]\displaystyle{ \text{Acc}_\text{equip} }[/math] the accuracy stat of the plane.

[math]\displaystyle{ \text{Acc}_\text{proficiency} }[/math] the plane proficiency accuracy bonus. See here for more details. Unclear if applied here or after [math]\displaystyle{ \text{Hit}_\text{cap} }[/math]. If applying here, skip [math]\displaystyle{ \text{Acc}_\text{proficiency} }[/math] for hit rate. The value is 12 for ❱❱ planes.

Notes

• For / Interceptors, the and stats are respectively "Anti-Bomber" and "Interception" and not Accuracy and Evasion.

Evasion

Evasion has two caps depending on the calculated base evasion of the ship. Base evasion is calculated as follows:

Evasion

[math]\displaystyle{ \text{Evasion}_\text{pre-cap} = \bigl\lfloor \left( \text{Evasion}_\text{ship} + \sqrt{2\text{Luck}} \right) \times \text{Mod}_\text{formation} \bigr\rfloor }[/math] With: [math]\displaystyle{ \text{Evasion}_\text{ship} }[/math] the displayed evasion of the ship, including any equipment stats and Visible Bonuses. [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] the formation modifier. It varies based on the attack being received. Please see Combat for more details. Vanguard's modifier is 1.0 if assuming values described in Vanguard Formation The evasion is then capped as follows: [math]\displaystyle{ \text{Evasion}_\text{pre-cap} }[/math] [math]\displaystyle{ \text{Evasion}_\text{cap} }[/math] ≤ 40 [math]\displaystyle{ \text{Evasion}_\text{pre-cap} }[/math] ≥ 40 & ≤ 65 [math]\displaystyle{ \lfloor 40 + 3\sqrt{\text{Evasion}_\text{pre-cap} - 40} \rfloor }[/math] ≥ 65 [math]\displaystyle{ \lfloor55 + 2\sqrt{\text{Evasion}_\text{pre-cap} - 65}\rfloor }[/math] Capped evasion is then modified by post-cap modifiers: [math]\displaystyle{ \text{Evasion}_\text{post-cap} = \biggl\lfloor \text{Mod}_\text{searchlight} \times \left( \text{Evasion}_\text{cap} + \text{Mod}_\text{sonar} + \text{Mod}_\text{CA} + \text{Mod}_\text{DD} - \text{Mod}_\text{fuel} \right) \biggr\rfloor }[/math] With: [math]\displaystyle{ \text{Mod}_\text{searchlight} }[/math] the Searchlights evasion penalty. It is 0.2 for any ship equipped with a searchlight (even if not triggered) and 1.0 otherwise. [math]\displaystyle{ \text{Mod}_\text{sonar} }[/math] the gained from Sonars' Improvements, that only applies to opening and closing torpedo attacks. It is 0 otherwise. [math]\displaystyle{ \text{Mod}_\text{sonar} = \sum_{\text{All Sonars}} 1.5\sqrt{\bigstar} }[/math] [math]\displaystyle{ \text{Mod}_\text{CA} }[/math] the CA/CAV night battle evasion bonus. It is 5 for CA(V) during Night Battles and 0 otherwise. [math]\displaystyle{ \text{Mod}_\text{DD} }[/math] the DD night battle evasion bonus. If the DD is equipped with a Surface Surface Radar AND a Skilled Lookout , then it is 10. [math]\displaystyle{ \text{Mod}_\text{fuel} }[/math] the remaining fuel penalty: [math]\displaystyle{ \text{Mod}_\text{fuel} = 75 - \text{Fuel} }[/math] If fuel is above 75%, the penalty is 0. The penalty is an integer and not a percentage. Remaining Fuel Penalty Battle # Remaining Fuel Penalty 2nd Battle 80% 0 3rd Battle 60% 15 4th Battle 40% 35 5th Battle 20% 55 6th+ Battle 0% 75

Notes

• Evasion term can be negative with the fuel penalty.
• The speed of the fleet is supposed to play a role in evasion. Currently, said increase is either nonexistent or too small to test,
• Using Underway Replenishment is a way to mitigate fuel penalties,
• Because of the evasion cap, trying to increase evasion above 65 has negligible effects,
• As most ships are capable of reaching 65 , trying to increase evasion using pre-cap means has little to no effect, this includes:
  • Increasing the (e.g. with boilers, even if improved),
  • Luckmodding ,
  • Choosing a weaker formation with an evasion bonus (except for Vanguard).
• Historical evasion exists but is not always measured due to the limited-time nature of events.

Special Cases

Vanguard Formation

This mechanic's effects are still under evaluation, so values are subject to change.

When a fleet is in Vanguard Formation it gives an accuracy malus to the opposite fleet. This malus is determined by 4 factors:

• Ship position in the fleet,
• Ship type,
• Normal or event map,
• Combat phase,

It is the same for the Abyssals.

It is called [math]\displaystyle{ \text{Mod}_\text{vanguard} }[/math] in the accuracy formulas above.

Debuffs

During Events, some Debuffs have been measured to give some additional bonuses of Accuracy and Evasion .

• Please, refer to the current Event page for up to date information.

Arctic Map Bonuses

On all "arctic maps", namely all World 3 maps, as well as some Event maps, the Arctic Camouflage (+ Arctic Equipment) gives:

• 3 Armor (non-stacking),
• Some Evasion .

Sources: [3] [4]

20.3cm Japanese Guns

So far, no hidden evasion bonus has been observed from equipping any gun on any ship.

• This idea comes from a misinterpretation of an ambiguous tweet by the devs [5].
