You gain a +1 bonus to all attack rolls and damage rolls made with this magic weapon. When making a melee attack, this weapon deals an extra 1d4 thunder damage to any target it hits. When making a ranged attack, this weapon deals an extra 1d4 lightning damage.

When you roll a Natural 1 on an attack roll with this weapon, the dagger misfires and damages you instead. You must make a Constitution saving throw with a DC of 13 or suffer 2d8 thunder damage and drop the dagger. On a successful save, you take half as much damage and do not drop the dagger. If this effect occurs more than three times in one day, the dagger will shatter on the fourth misfire.

Finesse. When making an attack with a finesse weapon, you use your choice of your Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls.

Light. A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.

Thrown. If a weapon has the thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon. For example, if you throw a handaxe, you use your Strength, but if you throw a dagger, you can use either your Strength or your Dexterity, since the dagger has the finesse property.

Proficiency with a Dagger allows you to add your proficiency bonus to the attack roll for any attack you make with it.
