You create 8 pillars of magical darkness. These pillars take up a 5 ft x 5 ft space and are 15 ft tall. You must place these pillars contiguous with each other. A creature with darkvision can't see through this darkness, and nonmagical light (other than sunlight, see below) can't illuminate it.
If any of this spell's area overlaps with an area of light created by a spell of 2nd level or lower, the spell that created the light is dispelled.
Any of this spell's area overlaps that overlaps with an area of light created by a spell of 3rd level or direct sunlight, then that area is reduce to a translucent black film which only provides 3/4 cover with a duration of 1 minute.
At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the number of pillars created is increased by 2 for each slot level above 4th.
