Bloodletting

A flash of flensing energy lashes out at a target of your choice within range. Make a ranged spell attack against the target. On a hit, the target takes 4d6 necrotic damage, and must make a CON saving throw or be left bleeding. A bleeding creature takes 1d4 necrotic damage at the end of each of its turns. The creature repeats the CON save after it takes damage from the bleeding effect.

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