Blood Arrow

Casting this spell deals 1d12 damage to you. A metal arrow formed from blood streaks toward a target within range. Make a ranged spell attack against the target. On a hit, the target takes 1d12 piercing damage immediately and on a failed constitution saving throw the creature takes 2d4 necrotic damage at the end of their next turn and every turn after that until they remove the arrow. Removing the arrow takes an action. On a miss, the arrow flies past harmlessly.

At Higher Levels. When you cast this spell using a spell slot of 2rd level or higher, the damage initial piercing damage increases by 1d12 and the latter necrotic damage increases by 1d4 for each slot level above 2nd.
