A character given a move action can move up
to its speed value in squares across the map.
A character might have a power or ability that
affects how it can move. A character does
not have to move its full speed value, and it
can choose to move 0 squares. Characters
can move diagonally.
When a character moves in the same direction–
horizontally, vertically, or diagonally– without altering
the direction within the movement, it is said to be
moving in a direct line. A character moving in a
direct line might move as little as one square.
