Plane Bound

The planewatcher is immune to any spell or effect that would force it to leave its current plane, unless it wants to leave.

Word-Bound

The planewatcher always knows the direction and distance to any creature that dispels, breaks, or otherwise avoids the geas of the promise it made via Planar Ultimatum, provided the planewatcher and the creature are on the same plane of existence.

Planar Ultimatum

The planewatcher demands one creature grappled by it to return to the creature's home plane within 24 hours. If the creature doesn't swear to do so, it must make a DC 17 Constitution saving throw, taking 45 (10d8) radiant damage on a failed save, or half as much damage on a successful one If the creature swears to return, it becomes affected by the geas spell for 30 days, which compels the creature to return to its home plane as soon as possible.
