Arcane Smell Detection

You awaken your sense of smell to the subtle scents left behind by magic. For the duration, you can perceive the scent of magic within 30 feet of you. You immediately know if there is magic present within range, although you don't automatically know its location. As an action, you can focus your senses on a creature, object, or 10-foot area you can perceive, learning: Whether it is magical. The school of magic, if any. Whether the magic is currently active, dormant, or is merely lingering residue. The approximate strength of the magic: faint, moderate, strong, or overwhelming. You can also recognize the distinctive magical scent of a spell or magical effect you have previously encountered. If you encounter the same magic again within the spell's duration, you recognize it as familiar. Additionally, you can smell magical residue left behind within the last 24 hours. The older the residue, the fainter the scent. A particularly powerful magical effect may leave a detectable scent for longer, at the DM's discretion.
