The touch of your shadow-wreathed dagger can siphon life force from others to heal your wounds. Make a melee attack against one creature within reach. On a hit, the target takes 1d4+5 Piercing damage plus 3d6 Necrotic damage, and you regain Hit Points equal to half the amount of Necrotic damage dealt.

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