This Black Furies rite will reveal the presence of potential caerns and sacred places. It will cause any sacred place nearby to glow with a dim blue light in the eyes of the ritualist, and if the ritualist closes her eyes and concentrates, she will be drawn towards the sacred place. The rite is usually cast in the morning and lasts all day, but requires the expenditure of a Gnosis point. If the ritualist enters battle, the rite must be re-cast.
Standard roll for Rite of Mysticism.
