Bag of Big Boom Berries

You have a small hemp pouch containing 10 Boom Berries. These magical berries explode upon impact and replenish after a long rest. Choose a place within range, you throw the Big Boom Berry.  The Boom Berry will explode on impact. Each creature in a 10-foot radius sphere centered on that point must make a dexterity saving throw. A target takes 1d12 fire damage on a failed save, or half as much damage on a successful one. Inside initiative this is done as a bonus action.

Notes: Damage: Fire
