When you take the [[Actions In Combat#Attack|Attack]] action and attack with a [[Weapon Properties#Light|Light]] melee weapon that you’re holding in one hand, you can use a [bonus action] to attack with a different [[Weapon Properties#Light|Light]] melee weapon that you’re holding in the other hand. You don’t add your ability modifier to the damage of the bonus attack, unless that modifier is negative or unless otherwise specified.
If either weapon has the [[Weapon Properties#Thrown|Thrown]] property, you can throw the weapon, instead of making a melee attack with it.
