Blood Spear

You cast forth a mystical spear of blood at a target. For each small size or larger fresh corpse or dying creature containing blood within 10 ft. of you, up to a maximum of six, you may cast forth an additional spear at a different target. Make a ranged spell attack, dealing 6d6 piercing damage on a hit, increased by 1d6 for each additional spear generated. You have advantage on the attack roll against a target if you used the blood of the target as a component.

Casting this spell inflicts 1 failed death save on any dying creatures you use to supplement your spell. Corpses used to supplement your spells are drained of blood, and do not supplement further castings. If there are no creatures or corpses within range, the caster may voluntarily take 1 point of damage to generate enough blood to power the spell should you lack the material component.

 At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
