Adamantine Dagger

This weapon or piece of ammunition is made of adamantine, one of the hardest substances in existence. Whenever this weapon or piece of ammunition hits an object, the hit is a Critical Hit.

Nick (Mastery): When you make the extra attack of the Light property, you can make it as part of the Attack action in· stead of as a Bonus Action. You can make this extra attack only once per turn.

Finesse: When making an attack with a Finesse weapon, 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: When you take the Attack action on your turn and. attack with a Light weapon, you can make one extra attack as a Bonus Action later on the same turn. That extra attack must be made with a different Light weapon, and you don't add your ability modifier to the extra attack's damage unless that modifier is negative. For example, you can attack with a Shortsword in one hand and a Dagger in the other using the Attack action and a Bonus Action, but you don't add your Strength or Dexterity modifier to the damage roll of the Bonus Action unless that modifier is negative.

Thrown: If a weapon has the Thrown property, you can throw the weapon to make a ranged attack, and you can draw that weapon as part of the attack. If the weapon is a Melee weapon, use the same ability modifier for the attack and damage rolls that you use for a melee attack with that weapon.
