Bloodflame Talons

You slash the air, creating lacerations at a point within 5 feet of you. Each creature other than you within 5 feet of that point must make a Constitution saving throw. A creature takes 3d4 damage on a failed save, or half as much on a successful one. 

If a creature rolls a 1 on its saving throw, it takes an additional 5d4 piercing damage as it hemorrhages blood from its body.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 for each slot level above 1st.
