no edit summary
This page is to provide an in-depth look into the hit rate mechanics in-game for '''single/combined fleets and land-based air squadrons'''. The formulas presented in this page are still subject to change as more testing is done.
*'''Please note that all formulas between <math>\lfloor \ \rfloor</math> are rounded down.'''
=Hit Rate=
The hit rate is used by all attacks.
<math>\text{Hit %} = \bigl\lfloor \text{Hit}_\text{cap} \bigr\rfloor + \text{Acc}_\text{proficiency} +1</math>
Where, the Capped Hit Rate <math>\left( \text{Hit}_\text{cap} \right)</math> is:
<math>\text{Hit}_\text{cap} = \text{cap}_\text{max}\left( \text{cap}_\text{min} \left(\text{Accuracy}_\text{atk} - \text{Evasion}_\text{def}\right) \times \text{Morale}_\text{defender} \right)</math>
* <math>\text{Accuracy}_\text{atk}</math> is the calculated accuracy of the attack. Please see [[#Accuracy_Formulas|below]] for the various accuracy formulas.
* <math>\text{Evasion}_\text{def}</math> is the calculated evasion of the defending ship. Please see [[#Evasion_Formulas|below]] for the various evasion formulas.
* <math>\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#Morale Effects|Morale and Fatigue]] for more details.
** Sparkled is '''0.7''',
** Normal is '''1.0''',
** Orange is '''1.2''',
** Red is '''1.4'''.
* <math>\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 [[Plane Proficiency|{{TextGlow|'''❱❱'''|black|text-colour=gold|glow-size=2px}}]] ranked planes.
'''Hit Rate Caps'''
There is a minimum and maximum hit rate in the game.
* The minimum of <math>\text{cap}_\text{min}\left(x\right)</math> '''is 10'''.
* The maximum of <math>\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.
=Critical Hit Rate=
The following are the various formulas for determining critical hits for attacks.
* Shelling/ASW (including carriers): <math>\lfloor 1.3 \times \sqrt{\text{Hit}_\text{cap}} \rfloor + \text{Crit}_\text{proficiency} + 1</math>
* Torpedo: <math>\lfloor 1.5 \times \sqrt{\text{Hit}_\text{cap}} \rfloor + 1</math>
* Airstrike: <math>\lfloor 0.2 \times \sqrt{\text{Hit}_\text{cap}} \rfloor + \text{Crit}_\text{proficiency} + 1</math>
* Night Battle (including carriers): <math>\lfloor \left(1.5 + \text{Const}_\text{contact} \right) \sqrt{\text{Hit}_\text{cap}} \rfloor + 1</math>
* Shelling Support: <math>\lfloor 1.0 \times \sqrt{\text{Hit}_\text{cap}} \rfloor + 1</math>
* Airstrike Support: <math>\lfloor 0.2 \times \sqrt{\text{Hit}_\text{cap}} \rfloor + 1</math>
* <math>\text{Crit}_\text{proficiency}</math> is the plane proficiency critical bonus. Please see [[Plane Proficiency]] for more details.
* <math>\text{Const}_\text{contact}</math> is the night contact constant from {{Night Recon}} {{Equipment/Link|Type 98 Reconnaissance Seaplane (Night Recon)|Type 0 Reconnaissance Seaplane Model 11B Kai (Night Recon)|text=Night Recons|link_category=Night Recon}}. It is '''0.07''' if night contact is triggered, '''0''' otherwise.
=Accuracy Formulas=
Below are the common variables used in all accuracy formulas:
* <math>\text{Level}</math> is the level of the attacking ship.
* <math>\text{Luck}</math> is the luck {{Luck}} of the attacking ship.
* <math>\text{Acc}_\text{equip}</math> is the total accuracy {{Hit}} provided by the equipment calculated as <math>\text{Acc}_\text{equip base} + \text{Mod}_\text{Impr} \times \sqrt{\bigstar}</math>
** <math>\text{Acc}_\text{equip base}</math> is the base accuracy {{Hit}} displayed on the equipment.
** <math>\text{Mod}_\text{Impr}</math> is the equipment's [[Improvement]] modifier for the applicable attack.
** <math>\bigstar</math> is the equipment's improvement level.
* <math>\text{Mod}_\text{formation}</math> is the formation modifier for the applicable attack. Please see [[Combat#Formation Selection|Combat]] for more details.
* <math>\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. Please see [[Morale_and_Fatigue#Morale Effects|Morale and Fatigue]] for more details.
** Sparkled is '''1.2''',
** Normal is '''1.0''',
** Orange is '''0.8''',
** Red is '''0.5'''.
'''Notes:'''
* Because of the number of modifiers to accuracy in-game, it is trivial to increase accuracy. Therefore it is '''more important''' to prioritize firepower.
==Daytime Shelling==
This formula applies to both surface shelling and carrier attacks during daytime combat. It does not apply to carrier airstrikes.
<math>\text{Accuracy}_\text{shelling} = \biggl\lfloor \left( \left( \text{Acc}_\text{base} + 2\sqrt{\text{Level}} + 1.5\sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip} \right) \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} + \text{Mod}_\text{fit} \right) \times \text{Mod}_\text{spotting} \times \text{Mod}_\text{AP} \biggr\rfloor </math>
* <math>\text{Acc}_\text{base}</math> is the base accuracy value of the attack.
** These values apply for Player as attacker and Enemy as targets. Values for Enemy attacker vs Player target are unclear/unknown, except single vs single = 90.

'''Notes:'''
* It is '''inadvisable''' to run any of the other setups beyond the most basic Gun+AP. This is because the other setups will interfere with artillery spotting and cost you better attack bonuses.
* Unlike when calculating damage, the bonus applies to all targets.
==Shelling Support==
This formula applies to surface shelling and carrier attacks during shelling support.
<math>\text{Accuracy}_\text{shelling support} = \biggl\lfloor \left( 64 + 2\sqrt{\text{Level}} + 1.5\sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip base} \right) \times \text{Mod}_\text{formation}? \times \text{Mod}_\text{morale} \biggr\rfloor </math>
* <math>\text{Acc}_\text{equip base}</math> does not include accuracy from improvement level.
* <math>\text{Mod}_\text{formation}</math> exists in KanColle Kai, but unclear if it applies to browser KanColle using the Daytime Shelling formation modifier of the main fleet.
==Torpedo Attacks==
This formula only applies to opening and closing torpedo attacks in day.
<math>\text{Accuracy}_\text{torpedo} = \left( 85 + 2\sqrt{\text{Level}} + 1.5\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{formation} \times \text{Mod}_\text{morale}</math>
* <math>\text{Mod}_\text{formation}</math> for '''torpedo attacks''' is as follows:

** Echelon: '''0.6''',
** Line Abreast: '''0.3''',
** Vanguard (Top & Bottom): '''?''',
** Accuracy modifiers for Combined Fleets is still unknown.
* <math>\text{Attack}_\text{torp}</math> is the final basic torpedo attack power of the ship. Please see [[Damage_Calculations#Torpedo_Attacks|Damage Calculations]] for details.
** The figure incorporates any pre-cap and post-cap modifiers and takes into account the attack cap.
** This means that engagement and damage state play a role in torpedo accuracy.
* <math>\text{Mod}_\text{ship}</math> is the innate torpedo accuracy of the ship. Currently, only Abyssal ships have values above <math>0</math>.
==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>\text{Accuracy}_\text{airstrike} = 95</math>
'''Important Notes'''
* Airstrike accuracy is a constant and '''not affected''' by any outside factors.
==Anti-Submarine Warfare==
This formula applies to all ASW attacks in the combat phase and support.
<math>\text{Accuracy}_\text{ASW} = \left( 80 + 2\sqrt{\text{Level}} + 1.5\sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{Impr} + 2\sum \text{ASW}_\text{sonar} \right) \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} \times \text{Mod}_\text{synergy}</math>
* <math>\text{Mod}_\text{formation}</math> for '''ASW''' is as follows:
** Line Ahead/Diamond: '''1.0''',
** Double Line/Echelon/Line Abreast: '''1.2'''.
*** Exception, certain combinations reduce this to '''1.0''':
**** Double Line attacking Line Abreast
**** Echelon attacking Line Ahead
**** Line Abreast attacking Echelon
** Vanguard (Top & Bottom): '''?'''
** Accuracy modifiers for Combined Fleets is still unknown.
* <math>\text{Acc}_\text{Impr}</math> does '''not''' include {{Hit}} accuracy stat of the equipment, only the amount from improvement related to ASW accuracy
* <math>\text{ASW}_\text{sonar}</math> is the '''base''' ASW stat of any sonars equipped.
* <math>\text{Mod}_\text{synergy}</math> is the synergy bonus from equipping certain combinations of ASW equipment.
** Synergy bonus is either currently bugged or so small it cannot be tested.
'''Notes:'''
* Equipping more sonars is the best way to boost ASW accuracy.
** Large sonars are not counted for this bonus.
==Night Battles==
This formula applies to '''all''' night battle attacks.
<math>\text{Accuracy}_\text{NB} = \bigl( \text{Mod}_\text{contact} \left( 69 + \text{Mod}_\text{star shell} \right) + 2\sqrt{\text{Level}} + 1.5\sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip} \bigr) \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} \times \text{Mod}_\text{special} + \text{Mod}_\text{searchlight} + \text{Mod}_\text{20.3cm} + \text{Mod}_\text{fit}</math>

** The value is '''12''' for [[Plane Proficiency|{{TextGlow|'''❱❱'''|black|text-colour=gold|glow-size=2px}}]] ranked planes.
<references/>
=Evasion Formulas=
Evasion has several caps depending on the calculated base evasion of the ship. Base evasion is calculated as follows:
<math>\text{Evasion}_\text{base} = \bigl\lfloor \left( \text{Evasion}_\text{ship} + \sqrt{2\text{Luck}} \right) \times \text{Mod}_\text{formation} \bigr\rfloor</math>
* <math>\text{Evasion}_\text{ship}</math> is the evasion of the ship '''including''' any visible equipment bonuses.
* <math>\text{Mod}_\text{formation}</math> is the formation modifier. It varies based on the attack being received. Please see [[Combat#Formation Selection|Combat]] for more details.
** Currently modifiers for Vanguard are unknown.
The various capped evasion formulas to calculate the final evasion rate is as follows:
* <math>\text{Evasion}_\text{base} < 40: \text{Evasion}_\text{cap} = \text{Evasion}_\text{base}</math>
* <math>40 < \text{Evasion}_\text{base} < 65: \text{Evasion}_\text{cap} = \lfloor 40 + 3\sqrt{\text{Evasion}_\text{base} - 40} \rfloor</math>
* <math>\text{Evasion}_\text{base} > 65: \text{Evasion}_\text{cap} = \lfloor55 + 2\sqrt{\text{Evasion}_\text{base} - 65}\rfloor</math>
Capped evasion is then modified by post-cap modifiers:
<math>\text{Evasion %} = \biggl\lfloor \text{Mod}_\text{searchlight} \times \left( \text{Evasion}_\text{cap} + \text{Mod}_\text{sonar} + \text{Mod}_\text{CA} + \text{Mod}_\text{vanguard} - \text{Mod}_\text{fuel} \right) \biggr\rfloor</math>
* <math>\text{Mod}_\text{searchlight}</math> is the searchlight evasion penalty. It is '''0.2''' for any ship equipped with a searchlight (even if not triggered) and '''1.0''' otherwise.
* <math>\text{Mod}_\text{sonar}</math> is the sonar improvement modifier that '''only applies to''' opening and closing torpedo attacks. It is '''0''' otherwise.
** <math>\text{Mod}_\text{sonar} = \sum_{\text{All Sonars}} 1.5\sqrt{\bigstar}</math>
* <math>\text{Mod}_\text{CA}</math> is the heavy/aviation cruiser night battle evasion bonus. It is '''5''' for heavy/aviation cruisers and '''0''' otherwise.
* <math>\text{Mod}_\text{vanguard}</math> is the Vanguard evasion bonus. This is different from the formation modifier that gets taken into account for base evasion. Bonuses are:
** For ships at the top (slots 1-2 or 1-3): Non-destroyers get a 5% bonus. Destroyers get a 20% bonus.
** For the rest of the ships at the bottom (slots 3-5 or 4-7): Non-destroyers get a 20% bonus. Destroyers get a 40% bonus.
* <math>\text{Mod}_\text{fuel}</math> is the remaining fuel penalty.
** <math>\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.

'''Notes:'''
* The speed of the fleet is supposed to play a role in evasion. Currently, said increase is either nonexistent or too small to test.
