Bonfire Berries

When this spell is cast, roll 1d4. Up to four berries are produced. Each is about the size of a key lime. They look blackened and cracked, and smell faintly of smoke. When one speaks the verbal command, all berries within a 120ft radius ignite, simultaneously. Each berry remains fresh and viable (even when wet) for up to 8 hours. When ignited, the flames fill a 1 foot diameter sphere, and burn for one minute (unless extinguished). The flashes ignite any flammable objects they come into contact with. Any creature that comes into contact with the flames must succeed on dexterity saving throw, or suffer 1d4 fire damage.
