Your armor permits you to press against any unattended surface large enough to hold you (typically 5 ft x 5 ft) and flatten into an illustration or engraving of yourself along the wall in whatever style you fit, or whatever is appropriate for the surroundings. When against the wall you can move along unbroken surfaces of sufficient size with no more difficulty than walking, and you benefit from the hardness of the material you are in (but no other properties of the material). You cannot enter materials made of force or are not corporeal. However, you can still be the target of attacks and spells, and your own attacks and spells do not extend beyond 5 ft or your reach, whichever is farther. While in the wall, a Disguise or Hide check can effectively hide you among other illustrations or engravings. Entering or leaving a surface is a move action.
