Acidic Chasm

You target a point on the ground within 100 feet of yourself, creating a line of bubbling, corrosive acid up to 60 feet long and 15 feet wide starting at that point. When a creature first enters the area of this spell on its turn or starts its turn in the area, it must succeed on a Constitution saving throw, taking 6d6 acid damage on a failure or half as much on a success. The area of the spell is considered difficult terrain. If an organic creature is killed by this spell, its body is corroded down to nothingness. 

At higher levels. When you cast this spell at higher levels, the damage dealt increases by 2d6 per level above 5th.
