Combat Styles
From FullPlate
Combat Styles are a kind of Combat Proficiency that reflect a Character's ability to fight and use their weapons beyond attacking in the normal fashion.
Characters gain a number of free Combat Styles from their Class. They also gain a number of Combat Proficiency points from their Level that may be spent on Combat Styles. Bonus Points may also be spent on Combat Styles.
Many Styles require other Styles or relevant Attribute scores of a certain level - a Character must meet all prerequisites for a Style they wish to take. Many Styles have multiple levels - unlike other Combat Proficiencies, a Character does not need the Weapon Specialization tag for higher levels, unless specifically stated.
