Darkness

Magical darkness spreads from a point you choose within range to fill a 15-foot-radius sphere for the duration. The darkness spreads around corners. A creature with darkvision can't see through this darkness, and nonmagical light can't illuminate it.

If the point you choose is on an object you are holding or one that isn't being worn or carried, the darkness emanates from the object and moves with it. Completely covering the source of the darkness with an opaque object, such as a bowl or a helm, blocks the darkness.

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.

At Higher Levels. When you cast this spell using a spell slot of 4th or 5th level, the duration is concentration up to 1 hour. When you cast this spell using a spell slot of 6th level or higher, the spell lasts until dispelled, without requiring your concentration. If any of the spell’s area overlaps with an area of light created by a spell equal to or lower than the spell slot used to cast darkness, the spell that created the light is dispelled.
