Boom Dust

You throw a pouch of explosive Boom Dust at a point within range. When exposed to an open flame, the dust ignites, creating a small explosion in a 10-foot radius. Each creature in that area must make a Dexterity saving throw, taking 2d6 fire damage on a failed save, or half as much damage on a successful one.

Additional Features:

• Concussive Blast: Creatures in the radius are pushed 10 feet away from the center on a failed save.
• Smoke Cloud: A cloud of smoke is released, providing concealment.

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

This representation captures the explosive and concussive nature of Boom Dust, providing both damage and strategic effects. Adjustments can be made based on your campaign or preferences.
