Emerald Blast

As you hold the bell as high above your head as you can, you scream “Emarald blast!”, Then a beacon of swirling emerald light and color pierces the sky above the caster. Shards of this light scatter, forcing any being in a one mile radius to make a DC 12 Dexterity saving throw or be ravaged by the blast, which deals 2d6 fire damage, 2d4 force damage, and ignites anything they are wearing or carrying. All flammable objects larger than medium are automatically ignited with emerald fire, if they are physically able to be ignited. Additionally, you may choose one object or creature that you can see, targeting them with a single, more powerful shard of fiery destruction. This creature is forced to make a DC 15 Dexterity saving throw or be dealt 15d6 fire damage and 10d4 force damage on a failed save, or half as much damage on a successful save. The swirling light causes the entire spells radius to be enveloped in bright light, cancelling out any sort of magical or nonmagical darkness.
