Tempest's Golden Fire

You extend your arms with open hands that individually ignite, one with a glimmering golden light and the other with an unruly flame that jettison magical energy of their own design. You create two individual 15-foot cones originating from the caster that cannot intersect, one dealing radiant damage, and the other dealing fire damage. Each creature within a 15-foot cone must make a Dexterity saving throw. A creature takes 4d6 damage of the designated type on a failed save, or half as much damage on a successful one.

Alternatively, you may combine the two cones to make a single, 30-foot cone that originates from the caster. Each creature in the 30-foot cone must make a Dexterity saving throw. A creature takes 3d6 fire damage and 3d6 radiant damage on a failed save, or half as much damage on a successful one.

The fire ignites any flammable objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage of each damage type increases by 1d6 for each slot level above 3rd.
