Reveal Secret Doors

Effect: You concentrate on the mirror and spin the glass marble across its surface. Slowly magic begins to build in the mirror, and as you finish the ritual with a few mighty words, the magic bursts forth illuminating secret openings in the area. Any secret doors, compartments, or openings within range become outlined with bright light. This light is visible to all creatures in the area.

If the door, compartment, or opening is concealed magically, make a Ritual Casting check versus the Potency of the concealment ability.
