A concentrated beam of fire hotter than a star blasts out from you in a 1,000-foot-long and 15-foot-wide line in a direction you choose. Each creature in the line must make a Constitution saving throw, with disadvantage if it is fully within the line.

On a failed save, the creature takes 30d12 fire damage and is applied with the following conditions for 1 minute; blinded, deafened, frightened, paralyzed and poisoned. The creature also gains four levels of exhaustion. On a successful save, the creature takes half as much damage and only receives the listed conditions until the end of its next turn. Instead of gaining four levels of exhaustion, the creature gains one level of exhaustion on a successful save. Any conditions inflicted by this spell can be removed at the same time by a greater restoration spell or similar magic except for exhaustion which must be targeted separately.

A creature killed by this spell is disintegrated along with any nonmagical equipment it was wearing or carrying, as well as any magical items of Rare or lower rarity. A creature with fire immunity targeted by this spell is treated as if it has fire resistance.

Once you finish casting this spell, you must make a Constitution saving throw against your spell save DC with disadvantage, which cannot be negated with any abilities or bonuses. On a failed save, you gain six levels of exhaustion due to the stress. On a successful save, you gain one level of exhaustion.
