The blade is incredibly delicate and fine, and is always cold to the touch.

You have a +1 bonus to attack and damage rolls made with this magic weapon.

On a critical hit the target takes an additional 2d6 necrotic damage and you heal an equivalent amount.  The target is prevented from regaining hit points until your next turn.

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