Blacklight

3-level Evocation

You invoke a stationary 20-foot radius sphere of magical darkness that emanates from a point you can see within range. This darkness blocks darkvision and all nonmagical light sources. However, you can see through the darkness normally. You may cast the darkness on an object and carry it with you. You may block the darkness emanating from the object by covering it. If the darkness crosses the path of an area of magical light caused by a spell of 3rd 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 level or higher, the radius of the sphere increases by five feet for every slot level above 3rd.
