Attribute - Attack Power

Attack Power is one of the most important attributes in Like a Boss. It determines how much damage your attacks cause, the power of some of your passive skills, and also the attack power of minions summoned by skills such as Commanding Shout (but not the minions that are natural to the Chapter you are playing in).

Attack Power, like most of the other stats, is a "Rating", meaning that the value displayed in your attribute sheet is converted to a percentage based on a formula. Attack Power can be increased through the use of accessories, passive skills, armor and certain active skills such as Blood Thirst. The formula to go from Attack Power Rating to the real bonus damage percentage the Attack Power attribute offers is the following:

1 + ( (Rating * 0.01) / ( 1 + ( Rating * 0.0001 ) ) ) = Damage Multiplier

For example, lets say you are a Warrior Boss, which has a Basic Attack default value of 34. If you have 0 Attack Power Rating, your damage will be multiplied by 1, resulting in 34 damage (ignoring other effects such as Critical Chance and the enemy's defense). Now, if you have 1000 Attack Power, the formula would look like this:

1 + ( ( 1000 * 0.01 ) / ( 1 + ( 1000 * 0.0001 ) ) ) = 10.09 Damage Multiplier

Which means that, having 1000 Attack Power will give you a 10.09 damage multiplier, transforming your 34 damage into 343.06 damage. The same logic is applied to some passive skills and to all active skills.
