You throw a small shining ball of fire at a creature within range that brands it with your mark. Make a ranged spell attack against the target. On a hit, the target takes 1d6 fire damage and is branded until the end of your next turn. While it is branded, the target takes an extra 1d4 fire damage every time it takes fire damage. If you cast this spell on a creature that is already branded, its current brand lasts until the end of your next turn, but it does not gain another brand.
