Detect Portals

For the duration, you sense the presence of all magical portals and gates within 30 feet of you. This includes natural portals (such inter-planar portals, vortexes, and color pools) and those created by spells or magic items. You can sense portals whether or not they are currently open. If you sense a portal in this way, you can use your action to determine the plane of existence the portal leads to.
