Blast of Darkness

5-level Conjuration

You conjure a wave of darkness that saps the life from creatures it touches. All creatures within a 90 foot cone originating from a point within 5 feet must succeed a Constitution saving throw or take 7d6 necrotic damage. The darkness persists for 1 minute, heavily obscuring the area for the duration. Any creature that starts their turn within the darkness is blinded until the start of their next turn.
At higher levels: When you cast this spell using a 6th level spell slot or higher, the damage increases by 2d6 for every spell slot expended above 5th
