Dexterity - Dex
Dexterity determines how agile, flexible and talented your character is for activities such as sneaking, gymnastics and climbing. Dexterity also affects how well you can defend yourself in combat and take cover from missiles.
A dexterous character moves smoothly and gracefully and will rarely be plump or clumsy. It does not have a great influence on playing the character; it shows rather indirectly (the character has skills and abilities that shape their behavior).
