BCF: Fighter Combat Vocation
All fighters, no matter the kind of fighter they are, develop or learn from their peers and community. This ongoing form of vocational training allows them to take their combat ability further beyond.
At Class Level 2, you choose your own combat vocation to follow. For you, this is your subclass.
Your subclass gives you features at Class Levels 2, 3, 6, 9, 12, 15, and 18. It also gives you a semi-unique Capstone choice at class level 20.
