At 3rd level, you gain the ability to magically sense the presence of a planar portal. As an action, you detect the distance and direction to the closest planar portal within 1 mile of you.
Once you use this feature, you can't use it again until you finish a short or long rest.
See the "Planar Travel" section in chapter 2 of the Dungeon Master's Guide for examples of planar portals.
