Blood Chain

Roll 1d8 and take the DMG as you use the Dagger to draw your own blood and use it to call out to the blood flowing in the veins of a single target within 15 ft. Target must make a CON save or take 1d10+ Spell ATK Mod Necrotic DMG, and be pulled up to 10 ft toward the caster. On a successful save, they take half DMG, and are pulled 5 ft closer instead of 10 ft.

After dealing damage, roll a CON check against your own Spell Save DC. On a success, you regain half the DMG dealt by this attack in HP.
