Crimson Bullet

Your drop of blood shoots toward a creature of your choice within range. Make a ranged spell attack against the target. On a hit, the target takes 4d6 piercing damage and must make a Constitution saving throw on a failed save the target is affected by the hemorrhage status effect.

Until a creature takes an action to stop hemorrhaging, the target takes 1d10 necrotic damage at the start of each of its turns. Undead and constructs can not be affected by the hemorrhage status effect. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
