Darkness

Darkness allows you to fill an area with magical darkness.

Effects
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 non-magical 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.

Spark Casting
At 2nd level Dark you can cast this spell without components and without expending a spell slot. Once cast you roll a d20, on a 10 or less you are blinded for 1 minute. You can take advantage of this feature once per long rest.
