Attack Power

Attack Power, also known as Battle Power, Attack and Weapon Power, is a recurring stat in the series that boosts the strength of physical attacks. It is typically associated with Strength, and is often a counterpart which is boosted by weapons rather than levels.

Final Fantasy IV
Attack is boosted by weapons and the Strength stat.

Formula for Attack:
 * Given by (where, if two weapons are equipped, the first term is doubled and "WpAtk" becomes the sum of both):
 * $$\frac{\mbox{Lv}+\mbox{Str}}{4} + \mbox{WpAtk}$$


 * Bows are an exception (where WpAtk is the sum of the bow and arrows, multiplied by 0.8 if the bow is held in the dominant hand instead of the arrows):
 * $$\mbox{WpAtk} + \frac{\mbox{Str}}{4}$$


 * Attack for Yang:
 * $$2( \mbox{Lv}+1 ) + \frac{\mbox{Str}}{4}$$

Formula for Attack Multiplier:
 * The highest amount for Multiplier any character can have is 19.
 * $$1 + \frac{2\mbox{Str} + \mbox{Agi}}{16}$$

Final Fantasy IV -Interlude-
Attack works identically to how it works in Final Fantasy IV.

Final Fantasy IV: The After Years
Attack works identically to how it works in Final Fantasy IV.

Final Fantasy V
Attack is boosted by weapons, while the Strength stat is boosted by job growth and other factors.

Final Fantasy VI
Also known as Batt.Pwr, Attack is easier to increase than Strength as it can be boosted with weapons instead of purely magicite and relic boosts. It is added with Strength2 before other factors are taken into account when determining damage.

Final Fantasy VII
Unlike other games, Attack is determined by the weapon power added with Strength. However, both stats add to the damage dealt independently.

The formula for base damage from a physical attack is as follows, where Att = Str + Weapon Power:
 * $$\mbox{Base Damage} = \mbox{Att} + \frac{(\mbox{Att} + \mbox{Lv})}{32} * \frac{\mbox{Att} * \mbox{Lv}}{32}$$

Final Fantasy XIV
Working differently to in other games, Attack Power solely calculates damage dealt by physical attacks, and is increased by whatever the selected class' Primary Attribute is increased by.

Final Fantasy Mystic Quest
The higher the number, the more damage the equipped weapon will deal. All weapons increase attack power.

The damage formula for physical attacks:
 * $$\frac{(\mbox{Attack}*4-\mbox{Defense})*\mbox{weakness}}{\mbox{split}}$$
