Dexterity measures hand-eye coordination, agility, reflexes, and quickness. This ability is especially important for movement and defense.

You apply your character’s Dexterity modifier to:

• Melee attack rolls.

• Ranged attack rolls, including those for attacks made with bows, crossbows, thrown weapons, and other ranged weapons.
• Armor Class (AC), provided that the character can react to the attack.
• Acrobatics, Aerial Agility, Airborne Riding, Ambidexterity, Aquatic Agility, Disabling Devices, Fast Drawing, Legerdemain, Rope Use, and and Dexterity Profession checks. These are the skills that have Dexterity as their key ability.
• Number of Disciplines and Skills a character begins with at 1st Level.

• Saving Throws versus Breath Weapons, fireballs and other attacks that you can escape by moving quickly.

Above average Dexterity has a slight tendency to correspond to a below average or average Weight-to-Height ratio. Player characters are not obligated to conform to this tendency.
