Spectral Sight is a Demon hunter exclusive ability where they ritually blind themselves with the claw of a Demon (or a dagger, each case varies) so that they are enabled to see Demons and Undead with greater clarity. Illidan, being the first Demon Hunter, got his sight from Sargeras himself. Spectral Sight is comprised of a variety of dark and light shadings. Light reflects off of objects allowing the Demon Hunter to navigate unhindered. Beings (namely Fel Users and Demons) shine a radiant assortment of colors making them easy to detect even when disguised.
