With your body, you utilize your own blood to produce bullets. Make a ranged spell attack roll against a target within range. Upon hit, the target takes 1d4 plus your Spellcasting Modifier in Necrotic damage. However, you take 1 damage that can't be reduced by any means to produce the bullet.
If you are half or less than of your maximum hit points, the d4s turn into d12s but take 2 hit points instead of 1.
At higher levels, you can conjure more bullets from your blood, sacrificing the necessary hit points for it and make additional attacks: two bullets at 5th level, three bullets at 11th level and four bullets at 17th level. You can use the bullets to attack the same target or different ones. Make a separate attack roll for each bullet.
Magical Synergy. If you have a ranged weapon that requires ammunition, you can cast this spell as a bonus action to produce ammunition but turns all of the damage to Necrotic, taking hit points equal to the amount needing to fill the ranged weapon.
In addition, any Eldritch Invocations that work with Eldritch Blast, you can apply it onto this cantrip.
