Wildfire Tempest

You create a massive storm of living fire that consumes everything in its path. Each creature that starts its turn in the area takes 6d8 fire damage and must succeed on a Quick save or be ignited. The fire spreads rapidly and can consume structures and terrain.

At 9th level, the damage increases to 7d8 fire damage, and the fire can create fire elementals.

The fire can spread beyond the initial area if flammable materials are present. The spell creates hampering ground and heavily obscures vision. The DN may limit the spread of fire to prevent it from consuming the entire battlefield.
