The Phasing deviation traps many inbetween parellel planes, which can result in both wanted and unwanted gaps in becoming physical and not.

Ethereal: When the rules state that your character enters the Ethereal Plane, refer to this section for the rules pulled from teh spell Ethereal Jaunt while this is the case: Material Plane creatures can't see you, and you can move through things on the Material Plane. You move at half your normal Speeds, but can move in any direction (including up and down). You can see onto the Material Plane within a radius of 60 feet; it is gray, hazy, and concealed from you. You can't affect the Material Plane, and you can't be affected by the Material Plane except by force effects and abjurations originating there.
When you return to the Material Plane, you fall if you're in the air (unless you can fly) and if you're inside an object you're pushed into the nearest open space and take 1d6 damage per 5 feet you were pushed.
