Characters must expend a Minor Action to significantly change position or move during their Turn. If the movement requires an Action Check, the character must expend a Major Action instead. In addition, the Adventure Guide may declare that movement through certain environmental conditions, such as knee-deep water or thick undergrowth, costs a Major Action, even if an Action Check is not required. In Rounds of 1 minute or less, a character may move up to Across the Room as a Minor Action. Moving farther than this requires the character to expend their Major Action as well.
