List of ship with special Mechanics
+
==Calculation==
 +
Installations generally have a lot of HP and/or armor. But multiple different cumulative bonuses exist against them, allowing for massive damage when using the right set-ups.
 +
These bonuses are divided into 5 groups and are calculated in the following order<ref>https://docs.google.com/document/d/1mXGyJ3yeNWeOmuGZQrXkcuGSuSEQYqmKhPelHMkzkGI/edit</ref>:
 +
# [[#Ship Type Bonuses|Ship type bonuses]],
 +
# [[#General Multiplicative Bonuses|General multiplicative bonuses]],
 +
# [[#Landing Craft Specific Bonuses|Landing craft specific bonuses]],
 +
# [[#Flat Damage Bonuses|Flat damage bonuses]],
 +
# [[#Post-Cap Bonuses|Post-cap bonuses]],
 +
# [[#Airstrike And Land-Base Bonus|Airstrike and land-base]] special cases,
 +
# [[#Installation-Like Warships|"Installation-like warships"]] special cases.
 +
*The bonuses' exact order is still under investigation and may be subject to changes.

===Post-Cap Bonuses===
 +
====Supply Depot Princess====
 +
{{Enemy/Link|Supply Depot Princess}} and its variants are currently the only installations to have post-cap bonuses.
 +
*These bonuses are applied after the damage soft-cap, and can reach the damage display cap of '''9999'''.
 +
** If the damage displayed is 9999, the actual damage can be higher.
 +
*Supply Depot Princess is a '''soft-skinned''' installation for purposes of Pre-Cap Bonuses.

;Notes:
 +
*A {{LandingCraft}} [[Landing Craft]] might be required to be equipped on the attacking ship for this bonus to be applied.
 +
*As it is the only post-cap bonus common to all installations, it has a great potential.
 +
*Due to the limited nature of Rations, this bonus is mostly "Pay To Win", and so is not recommended.
 +
 
 +
===Airstrike And Land-Base Bonus===
 +
For the damage formula, please refer to the [[Land-Based Air Squadron#Attack Power|LBAS]] and [[Damage_Calculations#Airstrike|airstrike]] page. The multiplier is chosen randomly between two values. The chance is roughly 50%.
 +
 
 +
There are exceptions:
 +
*For {{BluePlane}} [[Torpedo Bomber]]:
 +
** The {{torpedo}} torpedo stat is counted as 0 in airstrike,
 +
** The behavior is unclear for LBAS (the damage are overestimated).
 +
 
 +
*For {{JetFighterBomber2}}{{JetFighterBomber1}} {{EquipmentLink|Kikka Kai|Jet Keiun Kai|text=Jets|link=Jets}}:
 +
** There are inconsistencies with the bonuses.
 +
 
 +
*For the {{Large Land-based Aircraft}} {{Equipment/Link|Shinzan|Shinzan Kai|text=Land-Based Heavy Bombers|link_category=Land-Based Heavy Bombers}}:
 +
** Could have a higher modifier than other planes.

*Those bonuses are '''post-cap only''', meaning none of the "anti-installation bonuses" previously mentioned are applied.

*Be aware that the sample is limited (event only) so the information may be inaccurate and/or old<ref>Updated the 08/09/2022 during the [[Summer 2022 Event]] [https://nga.178.com/read.php?tid=33769345&rand=329].</ref>.

*The missing bonuses from new equipment can be extrapolated from the other installation bonuses.

Revision as of 16:35, 23 March 2024

Calculation

Installations generally have a lot of HP and/or armor. But multiple different cumulative bonuses exist against them, allowing for massive damage when using the right set-ups. These bonuses are divided into 5 groups and are calculated in the following order[1]:

  1. Ship type bonuses,
  2. General multiplicative bonuses,
  3. Landing craft specific bonuses,
  4. Flat damage bonuses,
  5. Post-cap bonuses,
  6. Airstrike and land-base special cases,
  7. "Installation-like warships" special cases.
  • The bonuses' exact order is still under investigation and may be subject to changes.

Notes
  • A Landing Craft Landing Craft might be required to be equipped on the attacking ship for this bonus to be applied.
  • As it is the only post-cap bonus common to all installations, it has a great potential.
  • Due to the limited nature of Rations, this bonus is mostly "Pay To Win", and so is not recommended.

Airstrike And Land-Base Bonus

For the damage formula, please refer to the LBAS and airstrike page. The multiplier is chosen randomly between two values. The chance is roughly 50%.

There are exceptions:

  • For Torpedo Bomber Torpedo Bomber:
    • The Torpedo Attack torpedo stat is counted as 0 in airstrike,
    • The behavior is unclear for LBAS (the damage are overestimated).
  • For JetFighterBomber2.pngJetFighterBomber1.png JetsKikka Kai
    Jet Keiun Kai
    :
    • There are inconsistencies with the bonuses.
