Capable Familiarity/Proficiency means the character has studied and has rudimentary familiarity with the unique approaches, specific implements (workspaces/tools), or place of the associated Feature (skill or trait). A “Proficiency Bonus” (PB) is the offset of having capability that is familiar and proficient vs. a character lacking these. Familiarity is by a specific frame of reference – group of devices, concept/technology, locale, subject, person, culture (must be an organized, homogeneous culture specific to region, nation, individual, or species if uniform throughout), or process. Experience in some larger context and dynamic situations is required to develop a level of usefulness where common mistakes of misapprehension are no longer made and greater capability can be applied. Contextual elements such as Advantage, Disadvantage, and GM Narration may offset a lack of PB.
The proficient character can apply their normal d20 Proficiency Bonus of their Character Advancement to their actions.
The proficiency character ignores non-proficiency penalties to their actions.
