A movement action is an action that attempts to move a character. It is played as a standard action but must involve one or more cards with the Movement keyword. For most characters this will require the use of one flow as a pseudo-card.
Once a character has rolled their action dice for their movement they must move at least one square (5') but they do not need to move the full distance allowed.
The mosey only uses one card (normally a pseudo-card) and always has a dice score of three. This allows the character to move up to three squares (15') on normal terrain.
