Drawing upon every ounce of willl power, anger, and magic left available you pour it into a 10ft wide beam of forceful energy scorching your target. Target must succeed strength saving throw against your spell save DC or take 15d12 force damage and 20d6 fire damage and be pushed back 100ft or take half as much damage and no knock back on a successful save.  Any target reduced to 0hp from this spell is immediately vaporized and cannot be resurrected unless by True Resurrection or the Wish spell.  The castor after casting this spell immediately takes 3 points of exhaustion and must succeed a DC20 Constitution saving throw or immediately fall unconscious. USE THIS SPELL WITH GREAT CAUTION!
