Minor Ring of Gaia

Wondrous Item Legendary (this item requires attunement)

While attuned to this ring the wearer has advantage on Nature Checks and you can't be forced into planar portals unless you choose to.   As an action, you detect the distance and direction to the closest evil 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.   Within 10 feet of an planar portal, you can make a Contitution check. if you succeed the portal closes. This feat drains your strength, you gain one point of exhaustion and cannot use this ability until your exhaustion level is gone.
