Evil Eye of Lesser Sight Thievery

You turn a vile gaze toward a creature of your choice within range that you can see. A creature caught in your gaze begins to lose it's senses. The creature must make a Charisma or lose any Darkvision it had and you gain Darkvision out to that range. The creature may repeat this saving throw at the end of its turn, ending the effect on a success. The spell also ends if the target is ever outside the spell’s range or if it has total cover from you.
