== Introduction: ==
 
This page studies the trigger rates & effectiveness of Artillery Spotting (弾着観測射撃), based on preliminary in-game testing. An optimal use of Artillery Spotting could considerably improve your fleet's daytime combat performances.
 
 
 
In brief, Artillery Spotting ''(aka. Day Battle Special Attacks) ''consists of two types of attack: Cut-In '''[CI] '''& Double Attack '''[DA]'''. When activated, the attacking ship receives a damage output ([http://kancolle.wikia.com/wiki/Combat#Damage_Calculations post-cap]) & accuracy bonus. You need to achieve at least Air superiority (AS) during aerial combat, and at least 1 [http://kancolle.wikia.com/wiki/List_of_Seaplanes_by_stats seaplane] equipped on the ship. The plane count can't be 0. More details could be found on the page [http://kancolle.wikia.com/wiki/Combat#Day_Battle_Special_Attacks_.28Artillery_Spotting.29 Game Mechanics -> Artillery Spotting] .
 
 
 
 
 
 
 
== Typical Set Ups for Artillery Spotting: ==
 
All the typical, basic set ups are listed below, click [http://kancolle.wikia.com/wiki/Combat#Common_Setups here] to see more possible combinations. Notice that any additional equipment (eg. [http://kancolle.wikia.com/wiki/Type_3_Shell Sanshiki]{{GreenAmmo}}) will NOT affect their attack modes or trigger rates.

''>> CI Damage: 130% / 150%. More CI expected than DA. Giving the highest base rate for triggering Artillery Spotting.''
 
 
 
 
 
 
 
== The Trigger Chance of Artillery Spotting: (Beta ver.) ==
 
Possible factors are listed below, followed by their '''''estimated''''' effects from experiments. These are best fit values from experiments, ''might ''be different from the actual ones, but they do give good estimates on the activation rates. To see how effects from each factor were evaluated, you may consult [http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Mid-Term_Report_on_the_ASTRE_Project Mid-Term Report on the ASTRE Project]. 
 
 
 
The first 5 factors are assumed to have more solid basis: 
 
# '''<u>Being the flagship / </u>'''旗艦  (+15% for both rates) 
 
# '''<u>Radar & type / </u>'''電探  (+30% CI chance, +10% DA chance, maximum) 
 
# '''<u>Air control state (AS. AS+) / </u>'''制空権の状態  (-12% on both if only Air Superiority is achieved)
 
# '''<u>Fleet total LoS (FLoS) / </u>'''艦隊合計索敵値  (+8% DA rate, +10% CI rate, per 100 additional LoS)
 
# <u>'''LoS stat on Seaplane / '''</u>水上機の索敵補正値  (minimal effects)
 
The following factors have negligible effects on the trigger rates:
 
*'''Type / number of caliber guns''' / 砲種 / 砲の数 (to be further evaluated)
 
* '''Health state / 損傷 '''([http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Preliminary_Study_on_the_Health_State_Modifier_(DA) Negligible effect] on DA chance; currently no test on CI)
 
The following factors ''might'' have an effect on the trigger rates:
 
# '''Fatigue / 疲労度'''  (No effect ?)
 
# '''Level / レベル '''([http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Preliminary_Study_on_the_Effects_of_Leveling_%26_FLoS_Difference#Comparative_Study_on_the_Effects_of_Leveling_.28DA_Chance.29 Preliminary test] suggests that leveling does affect DA chance, especially for ships below level 60)
 
# '''Formation / 陣形'''

=== Detailed Explanation: ===
 
1. Before we start, let's assume a ''standard situation'', in which '''''Fleet total LoS = 300,''''' test ships are ''beyond minor damage(小破未満) and morale condition = 49''. Fleet formation'' Line Ahead'', and ''Air Supremacy (AS+)'' is achieved. Based on preliminary test results from [http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Translation_on_Kuubowokyuu%27s_Exp%27ts_on_the_Trigger_Rates_of_Artillery_Spotting 艦これ-チラ裏検証] & [http://kancolle.wikia.com/wiki/User:Homuhomu123#-_Homu_Test:_Trigger_Rates_of_Artillery_Spotting_.2F_.E3.83.9B.E3.83.A0.E3.83.86.E3.82.B9.E3.83.88.EF.BC.9A.E5.BC.BE.E7.9D.80.E8.A6.B3.E6.B8.AC.E5.B0.84.E6.92.83.E3.81.AB.E3.81.A4.E3.81.84.E3.81.A6 Homu Test], we may come up with the following hypothesis:
 
 
 
- BB(V) equipped with 2 x Main & 1 Seaplane has '''DA rate ~ 50%'''.
 
 
 
- CA(V) quipped with 2 x Main & 1 Seaplane has '''DA rate ~ 50% '''
 
 
 
- BB(V) & CA(V) equipped with ''1 x Main + Secondary'' & Seaplane has '''''CI rate ~ 50%'''''
 
 
 
 
 
 
 
2. As '''fleet total LoS''' increases from 300 -> 400, the trigger rates increase slightly: ([http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Mid-Term_Report_on_the_ASTRE_Project#Fleet_total_LoS_.28FLoS.29 source])
 
 
 
- BB(V):  DA rate + 8%, per 100 additional FLoS   
 
 
 
- CA(V):  DA rate + 6%, per 100 additional FLoS  ~ ?
 
 
 
- For any type of ship: CI chance + 10%, per 100 additional FLoS
 
 
 
 
 
  
3. If an '''additional seaplane''' is added onto the 4th slot: ([http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Mid-Term_Report_on_the_ASTRE_Project#.5BDA.5D_3 source])
+
Artillery Spotting, commonly referred to as ''ArtySpot'', ''Daytime CI'', or simply ''Spotting'', is a series of special attacks that allow ships with specific equipment setups to perform Cut-in attacks during the Day Battle. These attacks grant '''post-cap''' damage bonuses as well as increased shelling accuracy.
  
- DA rate +5%
+
The Carrier-equivalent for Artillery Spotting is '''Aircraft Carrier Cut-in (CVCI)'''. Mechanically, they share the same core mechanics, but have different trigger conditions.
  
- CI rate +0%  ~ ?  
+
=Artillery Spotting=
 +
Artillery Spotting is a feature for ships that can launch {{Seaplane}} [[Seaplane]]s. Using special equipment setups, those ships may perform one of multiple special attacks. These attacks are often referred to as Cut-ins due to the way the equipment is displayed in the screen before the attacks are performed. Particular Cut-ins are often referred to by their acronym, such as APCI for Main AP Shell Cut-in, Sec CI for Secondary Gun Cut-in, etc.
  
- Actual effects are to be further tested. 
+
Cut-ins may be activated during a ship's turn and will override its normal shelling attack. Do note that the specific equipment being shown during the Cut-ins have no influence on the damage output.
  
 +
==Trigger Conditions==
 +
[[File:Air_Superiority_Aquired.png|thumb|right|The fleet attains Air Supremacy. Artillery Spotting and Aircraft Carrier Cut-ins can now be performed]]
 +
* The fleet must have attained {{color|green|'''Air Superiority (AS)'''}} or {{color|green|'''Air Supremacy (AS+)'''}} Air State.
 +
** For details on Air State, please refer to [[Aerial Combat#Stage 1 - Battle for Air Superiority|Aerial Combat - Stage 1]]
 +
* The ship must be equipped with at least one {{SPR}}[[Seaplane Recon]] or {{SPB}}[[Seaplane Bomber]] on a slot with size '''higher than 0'''.
 +
** {{SPF}} [[Seaplane Fighter]]s or {{Carrier Recon}} [[Carrier Recon]]s '''do not''' enable Artillery Spotting.
 +
** '''Main Suisei Cut-in''' specifically ignores this condition.
 +
* The ship must be equipped with at least one {{Large Gun}}{{Med Gun}}{{Light Gun}}{{Main Green}} '''[[Main Gun]]'''.
 +
* The ship must use a Surface Shelling attack.
 +
** This therefore excludes carrier and [[ASW]] shellings.
 +
* The ship must not be {{color|red|'''Heavily damaged (大破)'''}}.
  
 +
==Setups and Attack Types==
 +
[[File:Main_Main_Cutin.png|thumb|right|Musashi performing Main AP Shell Cut-in (APCI)]]
 +
Different setups have different conditions, trigger rates, damage, and number of hits. Cut-ins are determined by the attack's prerequisites as well as the previously stated trigger conditions.
  
4. If we use a '''radar''' on the 4th slot''',''' and compare it with the standard situation: ([http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Mid-Term_Report_on_the_ASTRE_Project#Fourth_Slot_Equipment_.28Radar.2C_AP_Shell_or_Extra_Seaplane.29 source])
+
For a given Cut-in, any other equipment can be added on the remaining slots. Be wary that adding certain equipment may change the Cut-in that will be rolled. Meeting prerequisites for multiple Cut-ins grants each a chance to be activated: in this case, the Cut-ins will be rolled in order of priority from '''top to bottom'''.
  
- DA rate rises by 3% ~ 10%

* If all rolls fail or the ship meets no Cut-in requirements, then it'll perform a Single Attack: a default 1 hit, no damage modifier shelling attack.
 +
* If an Artillery Spotting attack is evaded, it will deal [[Scratch Damage]] instead.
 +
* If valid set-ups for both Suisei-CI and Zuiun-CI are used, only the Zuiun-CI may trigger.

5. Different seaplane scouts vary slightly in the DA chance bonus: ([http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Mid-Term_Report_on_the_ASTRE_Project#Type_of_Seaplane source])
+
Aircraft Carrier Cut-in, or CVCI for short, is a feature for ships that can launch {{Torpedo Bomber}}{{Dive Bomber}}{{Fighter}}Carrier-based planes. Similar to Artillery Spotting, using special equipment setups, those ships may perform one of multiple special attacks.  
 
 
- '''Type 0 Observation Plane''' & '''Prototype Seiran''' ''(+ 6 LoS)'' give the highest bonus. (+2%) ?
 
 
 
- Night Scout ''(+ 3 LoS)'' provides less bonus on DA chance (-2%) ?
 
  
- Different seaplanes have no effect on CI chance ??
+
CVCI may be activated during a ship's turn and will override its normal shelling attack.

6. For standard BB(V)s, aka non-Yamato class BBs, radars could be replaced by '''AP Shells''' for a cut-in setup (Main + Sec / AP / Seaplane), which gives ~20% trigger chance bonus on CI ([http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Mid-Term_Report_on_the_ASTRE_Project#.5BCI.5D_3 source]). However, you could also use AP shells (or Secondary)''' '''for a''' <u>hybrid set up</u>''' (2 Main / AP (or Secondary) / seaplane).

== Artillery Spotting Trigger Rate Estimate: (Beta ver.) ==
 
NOTE: As mentioned before, these calculation only serves as rough estimates on your ship's artillery spotting chances. More credible tests (#ATK > 170 for p > 80%, while #ATK > 256 for p < 60%, minimun) are required to come up with a better formula. Deviations from actual test results are supposed to be less than 5%, otherwise reworking on the formula should be considered. This does not include effects from HP status(小破・中破), and undetermined factors like formation & special ships / maps, etc. The estimates on which the true probability is closer to 50% will be less accurate.

== Effectiveness of Artillery Spotting ==
 
=== DA: ===
 
- Lower activation rate compared to daytime CI. 
 
 
 
- If each attack is counted separately, DA increases shelling accuracy ([http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Preliminary_Study_on_the_Effects_of_Leveling_%26_FLoS_Difference#Do_Double_Attacks_Increase_Your_Shelling_Accuracy_.3F source], scratches are not counted).
 
 
 
- More dependent on accuracy if you wish to maximize the damage output ('''120% post-cap''' x 2)
 
 
 
- <u>For CA(V) using DA setup + radar</u>: ({{RedGunMedium}}{{RedGunMedium}}{{Seaplane}}{{Radar}})
 
* If head-on, T-disadvantage and/or low firepower, DA would usually be a double-scratch on the enemy with heavy armor (unless critical).
 
- <u>For BB(V) using DA setup + radar</u>:
 
* If high activation rate guaranteed (eg. flagship), DA is recommended for enemy weaker than [http://kancolle.wikia.com/wiki/Battleship_Ru-Class Ru-Class Battleships]. ([http://kancolle.wikia.com/wiki/User_blog:Nainodel/All_About_Firepower#How_much_damage_will_I_deal.3F source])
 
* In another word, if either attack could wreck the enemy, preferably using DA due to higher chance of hitting the target.
 
- '''''AP shells''''' are accessible to BB(V), but provides a lower base DA chance.
 
 
 
 
 
=== CI: ===
 
- Activate frequently during daytime battle (w/ radar), more reliable trigger-rate-wisely.
 
 
 
- It gives accuracy boost. ([http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Evaluation_of_Radar_Modifiers_on_Cut-In_Chance#.5B_Exp.27t_H_.5D source 1], [http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Evaluation_of_Radar_Modifiers_on_Cut-In_Chance#.5B_Exp.27t_J_.5D_2 2])
 
 
 
- <u>For CA(V) using CI setup + radar</u>: ({{RedGunMedium}}{{YellowGun}}{{Seaplane}}{{Radar}})
 
* Maximum damage is '''''120% post cap''''',''''' '''''when radar CI is triggered.
 
* Despite the highest activation rate, it provides a chance (~40%) to trigger secondary gun CI, which has only '''110%''' damage modifier post-cap. This will be awkward when facing heavy armor enemies.
 
* Therefore, not recommended against ships stronger than CA.
 
* If you're confident with your firepower, avoiding overkill on weak enemies, and/or pursuing higher activation rate, CI + radar is usually a good choice. For example, to prevent ships from stealing MVP.
 
- <u>For CA(V) using secondary gun hybrid setup</u>: ({{RedGunMedium}}{{RedGunMedium}}{{YellowGun}}{{Seaplane}})
 
* Since an additional gun is added, while the CI damage modifier is '''130% post-cap''', this setup is more powerful than the previous one.
 
*  Therefore, recommended against tougher enemies.
 
* However, it does not provide vital bonus on accuracy or LoS. Besides, this setup will shift DA to Cut-In during [http://kancolle.wikia.com/wiki/Combat#Night_Battle_Special_Attacks night battle], the trigger chance of which is very luck-dependent.
 
- <u>For BB(V) using AP shell</u>:
 
* '''''130% post-cap''' damage for CI setup + AP. (''{{RedGunHeavy}}{{YellowGun}}{{Seaplane}}{{RedAmmo}}'')''
 
* '''150% post-cap, '''for AP shell hybrid setup. ({{RedGunHeavy}}{{RedGunHeavy}}{{RedAmmo}}{{Seaplane}})
 
* Trigger rates are less volatile with respect to the changes in FLoS, but more penalized when Air Supremacy (AS+) is not achieved.
 
*  Preliminary study shows AP shell provide 10+ additional firepower against enemies with heavy armor. Therefore, this setup is quite recommended when dealing with [http://kancolle.wikia.com/wiki/Battleship_Ru-Class Ru-Class Battleships] and above.
 
 
 
 
 
=== General: ===
 
- Artillery Spotting (DA & CI) cannot miss, but may scratch the target due to weak shelling power and/or low accuracy. Scratching will inflict ~10% of the target's '''''current HP''''' as damage.   
 
 
 
- In-depth study on the effectiveness of BB(V) using AP hybrid setup: [http://kancolle.wikia.com/wiki/User_blog:Nainodel/All_About_Firepower#How_much_damage_will_I_deal.3F Comparative study on DA vs CI with sample enemies] ''(by Nainodel)''.   
 
 
 
- Preliminary test results [[http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Shelling_Accuracy_Test_Results_(Source_to_be_cited)#II_-_The_Overweight_Penalty_on_FBB Source 1]][[http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Shelling_Accuracy_Test_Results_(Source_to_be_cited)#III_-_The_Overweight_Penalty_on_BB_.28cont.27d.29 2]] shows the '''overweight penalty''' ''(eg. using too many 46cm on FBB)'' will somehow lower shelling accuracy from single attacks. It is suspected that this would affect Artillery Spotting, too. Nevertheless, the penalty could be largely offset by leveling (married ships), high morale ([http://kankoreshuukai.blog.jp/archives/2474494.html as high as possible]), and using 35.6cm (no variation suggested). Accuracy bonus from equipment ''might'' be helpful in countering the penalty.   
 
 
 
 
 
 
 
== Practical Use in Game & Suggestions ==
 
# '''Level up your ships & [http://kancolle.wikia.com/wiki/Marriage marry them].''' Ship levels affect their individual LoS stat, and a high FLoS would guarantee your ships to DA/CI frequently in battles. Also, if we assume a linear LoS growth, lv150 ships would have 50% more LoS than lv99 ships. It means if your central fleet is at lv99, they'd probably have FLoS ~400 (+10% DA/CI chance). When they're leveled up to lv150, you'll have FLoS ~600 (+30% DA/CI chance).
 
# Since fatigue doesn't seem to penalize the trigger rates while DA / CI boosts shelling accuracy, you could use it to counter fatigue. For example, '''[http://kancolle.wikia.com/wiki/Tutorial:_Leveling leveling] your ships at 3-2a with red faces.''' This method could drastically speed up your leveling, but less resource friendly (more buckets & repair cost).
 
# If ELoS ([http://kancolle.wikia.com/wiki/Line_of_Sight effective LoS]) is prioritized, you wish to have more seaplane bombers, and/or you don't have good radars, '''''equip an extra seaplane on your 4th slot''''' is usually a good choice.
 
# '''For newer players, hybrid setup is recommended''' since your FLoS (fleet total LoS) is usually very low, which in turn will greatly penalize your ship's artillery spotting chances. Hybrid setup, however, has the highest base trigger chances while not so affected by FLoS. However, you should always get AS+(制空権確保) and maximize your ship's firepower through [http://kancolle.wikia.com/wiki/Modernization#Introduction modernization]. Please be aware that using 2 x Main + 1 x Sec would shift your DA into CI in night battles, which is very dependent on luck stat & placement (flagship)..

Artillery Spotting, commonly referred to as ArtySpot, Daytime CI, or simply Spotting, is a series of special attacks that allow ships with specific equipment setups to perform Cut-in attacks during the Day Battle. These attacks grant post-cap damage bonuses as well as increased shelling accuracy.

The Carrier-equivalent for Artillery Spotting is Aircraft Carrier Cut-in (CVCI). Mechanically, they share the same core mechanics, but have different trigger conditions.

Artillery Spotting

Artillery Spotting is a feature for ships that can launch Seaplane Seaplanes. Using special equipment setups, those ships may perform one of multiple special attacks. These attacks are often referred to as Cut-ins due to the way the equipment is displayed in the screen before the attacks are performed. Particular Cut-ins are often referred to by their acronym, such as APCI for Main AP Shell Cut-in, Sec CI for Secondary Gun Cut-in, etc.

Cut-ins may be activated during a ship's turn and will override its normal shelling attack. Do note that the specific equipment being shown during the Cut-ins have no influence on the damage output.

Trigger Conditions

The fleet attains Air Supremacy. Artillery Spotting and Aircraft Carrier Cut-ins can now be performed
  • The fleet must have attained Air Superiority (AS) or Air Supremacy (AS+) Air State.
  • The ship must be equipped with at least one Reconnaissance SeaplaneReconSeaplane Recon or Seaplane BomberBomberSeaplane Bomber on a slot with size higher than 0.
  • The ship must be equipped with at least one Large Caliber Main GunMedium Caliber Main GunSmall Caliber Main GunMain High-Angle GunMain Main Gun.
  • The ship must use a Surface Shelling attack.
    • This therefore excludes carrier and ASW shellings.
  • The ship must not be Heavily damaged (大破).

Setups and Attack Types

Musashi performing Main AP Shell Cut-in (APCI)

Different setups have different conditions, trigger rates, damage, and number of hits. Cut-ins are determined by the attack's prerequisites as well as the previously stated trigger conditions.

For a given Cut-in, any other equipment can be added on the remaining slots. Be wary that adding certain equipment may change the Cut-in that will be rolled. Meeting prerequisites for multiple Cut-ins grants each a chance to be activated: in this case, the Cut-ins will be rolled in order of priority from top to bottom.

Aircraft Carrier Cut-In

Aircraft Carrier Cut-in, or CVCI for short, is a feature for ships that can launch Torpedo BomberDive BomberFighterCarrier-based planes. Similar to Artillery Spotting, using special equipment setups, those ships may perform one of multiple special attacks.

CVCI may be activated during a ship's turn and will override its normal shelling attack.

Trigger Conditions

  • The fleet must have attained Air Superiority (AS) or <Air Supremacy (AS+) Air State.
  • The carrier must fulfill one of the equipment setups.
  • The carrier must be shelling a surface ship.

Setups and Attack Types

Different setups have different conditions, trigger rates, damage, and number of hits. Cut-ins are determined by the attack's prerequisites as well as the previous state trigger conditions.

For a given Cut-in, any other equipment can be added to the remaining slots. Be wary that adding certain equipment may change the Cut-in that will be rolled.

  • If a CVCI attack is evaded, it will deal Scratch Damage instead.

Note: The Critical Damage modifier granted by Aircraft Proficiency works differently when performing a CVCI.

Trigger Rates

Artillery Spotting and Aircraft Carrier Cut-Ins share the same trigger rate formula. The chance of successfully rolling and triggering a cut-in is mainly affected by the Air State and the "raw LoS", as well as some other factors like the type of CI, the ship's luck, and the Recons/Bombers currently in the fleet.

Trigger rate formula
[math]\displaystyle{ \begin{cases} \ \text{Trigger %}_\text{Cut-in} =& \dfrac{10 + \text{Base}_\text{ship} + \text{Mod}_\text{Flag} }{\text{Base}_\text{attack} } \times 100 \\ \ \text{if AS} & \ Base_{ship} = \Big\lfloor \lfloor \sqrt{Luck} \rfloor + 0.6 \times \bigg( \sum^{\text{Ship} }\text{LoS}_\text{Equip} + 1.2 \times \big\lfloor \sqrt{\text{LoS}_\text{Fleet} } + \frac{\text{LoS}_\text{Fleet} }{10} \big\rfloor \bigg) \Big\rfloor \\ \ \text{if AS+} & \ Base_{ship} = \Big\lfloor \lfloor \sqrt{Luck} \rfloor + 0.7 \times \bigg( \sum^{\text{Ship} }\text{LoS}_\text{Equip} + 1.6 \times \big\lfloor \sqrt{\text{LoS}_\text{Fleet} } + \frac{\text{LoS}_\text{Fleet} }{10} \big\rfloor \bigg) +10 \Big\rfloor \end{cases} }[/math]
