You blow on a small pile of bone shards in your hand, which then summons a much larger, deadlier storm of bone shards that spread out in a 30-foot cone. All creatures caught in the storm must make a Dexterity saving throw, taking 6d10 necrotic damage on a failed save, or half as much on a successful one. Creatures that fail their saving throws also gain a level of exhaustion from having bone shards embedded in their skin. Removing the shards requires an action and a Wisdom (Medicine) check with a DC equal to your spell save DC.
Otherwise, the condition is removed with a long rest, as normal.
At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
