Blood Drinking Seal

Create seven blood seals that orbit your head until the spell ends. You can use a bonus action to send one of the seals streaking toward one creature within 120 feet of you. When you do so, make a ranged spell attack. On a hit, the target takes 4d12 necrotic damage and you regain hit points equal to half the amount of necrotic damage dealt. Whether you hit or miss, the seal is expended. The spell ends early if you expend the last seal.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the number of seals created increases by two for each slot level above 7th.
