Darkness

Duration: 10 minutes, Concentration
Magical darkness spreads to fill a 15 ft radius
sphere that spreads around corners. A creature
with darkvision can't see through this darkness,
and nonmagical light can't illuminate it. If you
cast this spell on an object, the darkness emanates
from the object and moves with it. Covering the
source of the darkness with an object blocks the
darkness. If any of this spell's area overlaps with
an area of light created by a spell of 2nd level or
lowe
