The Rune of Clairvoyant Sight can only be activated once per long rest.
This rune allows you to see clearer than you ever have. With this rune, you will always be able to see through the Veil, even at its strongest.
You gain the ability True Sight:
True Sight allows the holder to see in both normal and magical darkness, see invisible creatures, and automatically detect visual illusions. You can perceive the true form of a shape changer, and see into the Ethereal Plane.
