Vulnerability Hex

You place a curse on a creature that you can see within range. The creature bursts into flames of hellfire, and until the spell ends, you deal an extra 2d6 psychic damage to the target whenever you hit it with an attack, and the target must make a Constitution saving throw at the start of each of its turns. A target takes 3d6 hellfire damage on a failed save, or half as much on a successful save. In addition, the target's armor class is reduced by 2 and has vulnerability to all attacks you make against it while this spell is in effect. At the end of each of its turns, the target can make a Wisdom saving throw. On a success, the spell ends on the target.

A remove curse cast on the target ends this spell early.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, for each slot level above 5th, the hellfire damage increases by 3d6, and the psychic damage increases by 2d6 .
