Ethereal Jaunt (Su): An ethereal marauder can shift from the Ethereal to the Material Plane as a free action, and shift back again as a move-equivalent action (or as part of a move-equivalent action). The ability is otherwise identical with ethereal jaunt cast by a 15th-level sorcerer.
Once a marauder locates prey, it shifts to the Material Plane to attack, attempting to catch its victim flat-footed., The creature bites its victim, then retreats quickly back to the Ethereal Plane. When badly hurt or wounded, the marauder escapes to its home plane rather than continue the fight.
A subtype applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. This book assumes that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have when on its home plane). An extraplanar creatures usually has a home plane mentioned in its description. These home planes are taken from the Great Wheel cosmology of the D&D game (see Chapter 5 of the Dungeon Master's Guide). If your campaign uses a different cosmology, you will need to assign different home planes to extraplanar creatures.
Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a transitive plane; the transitive planes in the D&D cosmology are the Astral Plane, the Ethereal Plane, and the Plane of Shadow.
