Blood Magic: Blood Bullet

By controlling the blood around them the spellcaster can create and fire a projectile of piercing blood at dangerous speeds, a target hit with this ranged spell attack takes 5d6 + spellcasting modifier in damage The target is considered bleeding and takes 1d6 + spellcasting modifier in damage every turn until they pass a Con save of 15, or another creature uses a Wisdom (Medicine) Check and passes with a 15 to end this effect.

If there is no blood for the caster to manipulate they can instead take 1d10 +4 in damage to themselves to create the blood needed. (If cast in this way this spell does not use a spell slot.)

At Higher Levels. If you cast this spell at 2nd Level or higher add 1d6 to the spells damage and bleeding effect. It also adds 1d10 to the sacrificed HP for every level past the first.
