Soul Affinity

You gain the ability to sense the presence of Souls as well as foreign creatures. You can use an action to focus your senses and detect any soul or ethereal being within 60 feet of you. You can also detect any aberration, celestial, fey, fiend or undead within 15 feet of you. This effect lasts for 1 minute. You can expend a charge to extend the duration by 1 minute. You can use this feature a number of times equal to your Wisdom modifier (minimum of one) and you regain all uses when you finish a long rest.
