This item looks like an ordinary compass. Instead of pointing to true north, a gate compass points to an area envisioned by the holder (or to the nearest portal leading to the area). It has the same chance of being on target or off target as if it were casting a teleport spell. Once the compass points to an area (either correctly or incorrectly), it will continue to point consistently to the area until it reaches the area or goes to another plane.
Prerequisites: Craft Wondrous Item, divination.
