Each weapon, spell, and damaging monster ability specifies the damage it deals. You roll the damage dice, add any modifiers, and deal the damage to your target. If there’s a penalty to the damage, it’s possible to deal 0 damage but not negative damage.
When attacking with a weapon, you add your ability modifier—the same modifier used for the attack roll—to the damage roll. A spell tells you which dice to roll for damage and whether to add any modifiers. Unless a rule says otherwise, you don’t add your ability modifier to a fixed damage amount that doesn’t use a roll, such as the damage of a Blowgun. See “Equipment” for weapons’ damage dice and “Spells” for spells’ damage dice.
