You fill the air with 4 flaming, daggers in a sphere centered on a point 5 feet in front of you. A creature rolls a DEX saving throw if they are in or enter the sphere. On a failed save, a creature takes 1d4 slashing damage for each dagger in the sphere and the spell persists. On a successful save, they take no damage and the spell ends. You may do any of the following with the sphere of daggers:

• When you cast the spell — and as a bonus action on each of your turns thereafter — you can expend one of the daggers, sending it streaking toward a point you choose within 30 feet from the center point of the sphere. Once a dagger reaches its destination or impacts against a solid surface, the dagger explodes. Each creature within 5 feet of the point where the dagger explodes must make a DEX saving throw. A creature takes 1d4 piercing damage on a failed save. On a successful save, creatures take no damage.
• When you cast the spell — and as a bonus action on each of your turns thereafter — you can chose to detonate all the remaining daggers in the sphere that are still flaming to deal the 1d4 force damage for each dagger detonated to all targets within 5 feet of the sphere. If you are within 5 feet of the sphere when you detonate it, you take 1d4 force damage.
• You may use an action to move the sphere up to 10 feet.

The spell ends if you move more than 30 feet away from the sphere, if a creature succeeds on their DEX saving throw from inside the area of the sphere, or if all daggers are extinguished.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the number of daggers created increases by one for each slot level above 3rd.

Prerequisites: Must have 2 daggers equipped, one in each hand, and enough daggers in your inventory to cover the rest used in the spell depending on the casting level. Spell does not expend the daggers in your inventory.
