Evangeline's Kiss of Death

You kiss a target of your choice that is not hostile toward you and make them feel pain down to their core. The target must make a constitution saving throw. It deals 10d6 + 10 necrotic damage on a failure, half as much on a success.

When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d6 for each slot level above 6th.
