dalla descrizione di blink:
While blinking, you can step through (but not see through) solid objects. For each 5 feet of solid material you walk through, there is a 50% chance that you become material. If this occurs, you are shunted off to the nearest open space and take 1d6 points of damage per 5 feet so traveled. You can move at only three-quarters speed (because movement on the Ethereal Plane is at half speed, and you spend about half your time there and half your time material.)
non e` proprio la stessa cosa, ma direi che puo` aiutare.
