Blessings of Darkness
An Umbral Court agent gains the Darkness domain at 1st level, using his class level as his effective cleric level to determine the effects of its granted powers. If he already possesses the Darkness domain from another class, his Umbral Court agent levels stack with levels in that class when determining the effects of his Darkness domain powers. The Umbral Court agent does not receive bonus spells or domain spell slots from his Umbral Court agent levels.
