Bloodtinge

Make a ranged spell attack against a creature you can see within range. The caster loses 1d4 hit points no matter whether the spell hits or not. If the spell hits, the target is shot with a bullet made from the caster’s blood, for the same amount of damage that the caster took, plus the caster’s spell modifier. If the caster is poisoned and the spell hits, the poison’s effects are also shared with the target.
