You point your finger toward a creature you can see within range. A ball of fire appears inside the target of this spell. The target must make a Constitution saving throw. Target takes 10d4 + 20 fire damage on a failed save, or half as much on a successful one. Additionally, if the target failed the saving throw, the target starts internal bleeding. The target has disadvantage on saving throws and attack rolls. The target can end this effect early by using an action to make a medicine check against your spell save DC.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the damage increases by 4d4 for each slot level above 7th.
