Rules of Dexterity

Dexterity (DX)

                      ±20 points/level
  Dexterity measures a combination of agility, coordination, and fine motor ability. It controls your basic ability at most athletic, fighting, and vehicle-operation skills, and at craft skills that call for a delicate touch. DX also helps determine Basic Speed (a measure of reaction time, B. 17) and Basic Move (how fast you run, B. 17). (This will be cover more in Rules of Move and dodge.)
  Those with nonhuman physiologies may, with the GM’s permission, purchase their DX with the following
limitation.
Special Limitations
  No Fine Manipulators: If you have either level of the disadvantage No Fine Manipulators (p. 145), you may purchase DX more cheaply. -40%.
