While the spell is active, a small red aura faintly radiates from your eyes. Any creature that is good aligned, you can see no matter what, and their presence is somewhat highlighted for you. This works on celestials and fey as well. While the spell is active, you can tell if any of these kinds of creatures are within 50 feet of you, and you have advantage on rolls to hit against them. This vision extends to 200 feet, and the highlight is seen through walls up to 1 foot in thickness.
