As a standard action, you can target a creature within 100 feet and plunge it into darkness. This creates an area of magical darkness that affects only the targeted creature and occupies its space. This darkness does not affect the creature’s visibility to other creatures, nor its ability to attempt Stealth checks to hide. The darkness overcomes all nonmagical light and is itself overcome by any magical light source. At 8th level, each time the creature takes an action that lets it move while the darkness persists, it must succeed at a Reflex saving throw or the area of darkness moves with it. Once the creature has failed a saving throw and the darkness has moved with it, the darkness remains stationary for the remaining duration of this effect.
