Bonechill

You call an audience of ghosts before you, each bringing a grave chill with them. Each creature in a 15-foot cone must make a Constitution saving throw. A creature takes 3d6 cold damage on a failed save. If the creature is of the Celestial, Fey, Plant or Beast types, it also takes an additional 1d6 necrotic damage.

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.
