Bloody Talons

You slash at a creature, attempting to lacerate its body with ribbons of necrotic energy. Make a melee spell attack against a creature within range. On a hit, the creature takes 2d6 necrotic damage, and it must succeed on a Constitution saving throw or take an additional 1d6 necrotic damage as its blood hemorrhages from its body. Creatures that do not have blood, such as constructs, automatically succeed on this saving throw.

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