Ranged Attacks with a Thrown Weapon
With a thrown weapon or a grenade, you can make a ranged attack at a target that is within the weapon’s maximum range and in your line of effect (see page 271). You add your Strength modifier to your ranged attack rolls with a thrown weapon, and to your damage rolls with weapons with the thrown special property. Do not add your Strength modifier to damage rolls with grenades.
