Blood Sling

You conjure a throwing knife made of your own blood, which you can hurl at a target within range. To cast this spell, you must sacrifice a small portion of your own health, taking 1d4 necrotic damage. The blood knife then forms in your hand.

Make a ranged spell attack against a target.
On a hit, the target takes damage as follows:

• 2d6 piercing damage.
• An additional 1d6 necrotic damage

On a miss, the blood knife dissipates harmlessly, and you take no additional damage from casting the spell..

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the piercing damage increases by 1d6 for each level above 2nd.
