Elucidating Solitary Fireball

A bright streak flashes from your pointing finger to a point you choose within range, where it blossoms with a low roar to engulf a single creature in searing flames, forcing the creature (if it speaks a language) to shout out a closely held secret. That creature takes 6d6 fire damage and shouts a closely held secret determined by the dungeon master (if the creature speaks a language), or half damage and does not have to shout their secret with a successful Dexterity saving throw. Solitary fireball does not ignite other flammable objects.

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