Drexa's Truth Bomb

The caster makes a declarative statement about the target creature. The creature must make a Wisdom saving throw. On a failed save, the creature takes 4d6 psychic damage. On a successful save, the creature takes half as much damage. If the spoken statement is true, especially an uncomfortable truth about the creature, the target instead takes 4d10 psychic damage.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 or 1d10 for each slot level above 2nd.
