The Adventure Guide can rule a character only has familiarity with an Action rather than actual expertise. These are Actions tangentially related to the MO, but not directly. When the Adventure Guide rules that a character has familiarity, the player still adds the character’s MO score to the Action Score, but the Adventure Guide adds a Drawback to the Difficulty Score. Additionally, when the character only has familiarity, the player may not add Benefits from Specializations to the Action Score.
