This spell causes the object touched to shed absolute darkness in a 60-foot radius. Even creatures who can normally see in the dark cannot see through this magical darkness. If the spell is cast on a small object that is then placed inside or under a lightproof covering, the spell’s effects are blocked until the covering is removed.
Daylight brought into an area of deeper darkness (or vice versa) is temporarily negated, so that the otherwise prevailing light conditions exist in the overlapping areas of effect.
Deeper darkness counters or dispels any light spell of equal or lower level, including daylight and light.
