Blood Creation Spear

As part of the casting of this cantrip, you inflict 2 points of damage to yourself. The blood from your self-inflicted injury forms into a sharpened spear of crimson that rapidly soars toward a creature within range, drying as it flies through the air. Make a ranged spell attack against the target. On a hit, the target takes 1d6 non magical piercing damage.
The spell creates more than one blood spear when you reach higher levels (you take 2 additional points of damage for every extra spear formed): two spears at 5th level, three spears at 11th level, and four spears at 17th level. You can direct the spears at the same target or at different ones. Make a separate attack roll for each spear.
