Divine Immolation

The target’s body is enveloped in powerful wicked flames but is still discernible. The target sheds bright light for 60 feet and dim light for an additional 60 feet.

While in this state, all attacks made by the target are replaced with fire damage + your spellcasting modifier. Attacks made against the target are made with disadvantage and must succeed on a Dexterity Saving Throw against your spell save DC or take 8d12 fire damage, half as much on a success.

Any flammable objects not being worn or carried touched by the target, they are set on fire.
