In BareBones Wuxia! one of the choices you make if you take a level in a warrior skill is what kung fu style to choose. Of those choices, kung fu styles come in two flavors, External and Internal.
External styles focus on unarmed and weapon combat at first and use chi overtly to damage opponents and shake off wounds.
Internal styles focus on the inward aspects of chi such as healing and lightness and then focus on unarmed and weapon combat uses of chi.
Both external and internal style practitioners can eventually learn all aspects of chi use. The distinction is only in how they begin. They will still arrive at the same destination.
