Crimson Missles

This spell is favored by vampires who have the access to magic. By sacrificing 3d4 of your own hit points, you fire three crimson blood missiles that you must roll to hit with using your spell attack modifier. These missiles deal 2d4 necrotic damage each. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the spell creates one more dart, and the component cost increases by 1d4, for each slot level above 1st.
