For purposes of this ritual, a walled area must be composed of solid posts, preferably wooden. Posts should be placed at least three pace, and at most five paces, apart and protrude out of the ground at least three feet. The posts should be clearly visible, and ideally clearly marked as 'special' - carved or painted with runes for example.

As with anything you might be taking onto a battlefield, or that is likely to have people fighting around or near it, the phys-reps should be as safe as possible (no sharpened points, for example). Please do not tie rope between the posts; if it is not clear where the boundary is, you will need to use more posts.

The ward can be taken down by moving, removing or defacing the warding signs, but {{{1}}} cannot do so themselves. Assuming it is not interfered with, the ward stays in place until the duration expires.
