Elements that are Involved in the Calculation of Damage

Attack Formation

Formation	Magnification
Line Ahead	100%
Double Line	80%
Diamond	70%
Echelon	60%
Line Abreast	60%

Night battle and air combat are not affected by formation choice.

Engagement Form

Form	Magnification
The Ocean-going War (同航戦)	100%
Hankou War (反航戦)	80%
T-war (Advantage) (T字戦（有利))	120%
T-war (Disadvantage) (T字戦（不利))	60%

Night battle and air combat are not affected by egagement form.

Affects both your fleet and enemy fleet.

T-war (Disadvantage) is avoided by equipping a Saiun (Carrier-Based Recon plane).

Illustration of Engagement Form

The Ocean-going War

Course of own fleet and enemy fleet are the same.

Fleet A	→	→	→	→	→	→
Fleet B	→	→	→	→	→	→

Hankou War

Course of own fleet and enemy fleet are opposite.

Fleet A	→	→	→	→	→	→
Fleet B	←	←	←	←	←	←

T-war

Course of own fleet and enemy fleet are 90 degrees different (which results in a T figure). A fleet is in advantage if it is coming from 「｜」direction, and is in a disadvantage if it is coming from 「―」direction.

Damage

Damage	Magnification
Minor Damage	100%
Half Damage	70%
Wreck	40%

Magnification does not affect plane attacks (needs confirmation because I'm not sure about google translate. Here's the link http://wikiwiki.jp/kancolle/?%C0%EF%C6%AE%A4%CB%A4%C4%A4%A4%A4%C6#lfa4fc2d)

Special Attack in the Night Battle

Cut-in

Weapon Type	Magnification
2X Torpedo	The 2 consecutive attacks - total 150%
Main Gun, Torpedo	The 2 consecutive attacks - total 130%
3X Main Gun	200%
2X Main Gun, Secondary Gun	175%

Double Attack

2 consecutive attack - total 120%. Always procs while cut-ins are only by chance and also affected by luck stat. (Japanese wiki confirmed that Yukikaze has a more chance of doing cut-ins than Shimakaze)

Critical Attack

Attack Type	Magnification
Normal Attack	100%
Critical Attack	150%

It should be noted that the critical message always appears when damage dealt is greater than or equal to 40. (If, on the other hand, the critical message appeared when the damage dealt was less than 40, then it was a critical hit.)

Amount of Ammunition Remaining

Ammunition Amount	Magnification
5 or more ammo bar	100%
4 ammo bar	80%
3 ammo bar	60%
2 ammo bar	40%
1 ammo bar	20%
0 ammo bar	Only Kasudame カスダメのみ

(Help: Confirmation needed if the wiki is indeed saying ammor bar. And what are game eyes? And what is Only Kasudame? Here's the link http://wikiwiki.jp/kancolle/?%C0%EF%C6%AE%A4%CB%A4%C4%A4%A4%A4%C6#d50cd57a)

Magnification also affect air warfare. 

Magnification is the same for day and night battle of the battle.

Help: Everything is taken from http://wikiwiki.jp/kancolle/?%C0%EF%C6%AE%A4%CB%A4%C4%A4%A4%A4%C6 . Some sections weren't added because I felt that the google translation wasn't accurate (or I didn't understand it at all). To those who can understand Nihongo, please help in adding those sections (and also proofread the things I put).
