Dexterity

Dexterity measures agility, reflexes, and balance.
Dexterity Checks
Make a Dexterity check to move nimbly, quickly, or quietly.
Attack Rolls and Damage
You add your Dexterity modifier to your attack roll and your damage roll when attacking with a ranged weapon, such as a sling or a longbow. You can also add your Dexterity modifier to your attack roll and your damage roll when attacking with a melee weapon that has the finesse property, such as a dagger or a rapier.
Armor Class
Depending on the armor you wear, you might add some or all of your Dexterity modifier to your Armor Class.
Initiative
Initiative determines the order of turns during combat. When combat starts, every participant rolls Initiative; they make a Dexterity check that determines their place in the Initiative order. The GM rolls for monsters. For a group of identical creatures, the GM makes a single roll, so each member of the group has the same Initiative.
