Dexterity

Dexterity (Dex) measures hand-eye coordination, agility, reflexes, and balance. This ability is the most important ability for Scoundrels, but it's also high on the list for characters who want to be good shots with ranged weapons or who want to handle the controls of a starship or speeder fairly well. You apply your character's Dexterity modifier to: Ranged attack rolls, such as with blasters, General and Reflex Defense (provided the character can react to the attack, Acrobatics, Initiative, Pilot, Ride , and Stealth checks (the Skills with Dexterity as the key ability).
