Blood Wound - Blood Magic

You stretch your hand toward the target creature. Red tendrils extend from you fingertips to the creature. The target must succeed on a Constitution saving throw. On a failed save, the creature takes 2d6 piercing damage as bleeding puncture wounds cover its body.

At the start of each of your turns while you are concentrating on the spell, you can use your bonus action to cause blood to leave its body, dealing 1d6 damage to the target. This spell ends early if the creature’s hit points are reduced to 0 or if you do not use your bonus action to cause this damage.

At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, the initial piercing damage increases by 1d6 for each slot level above 1st.
