When activated, two pathstones create a shimmering force field between them that acts as a solid barrier. The stones can be a maximum of 50 pied from each other, and the wall can be a maximum of about four pied tall. The stones are usually inserted in the ground and spaced out along a river bank to create a long, two-foot-height barricade. Venetian Walls can also be placed horizontally to create bridges able to sustain human weight. Even something as heavy as a horse is able to walk upon one, though it takes considerable training to coax a horse onto one. Multiple stones working together can create a much wider and stronger bridge. The original walls in Venice used a dynamic formula that could be turned on or off as the tides demanded. This formula also had room to modify the height of the walls. Outside of Venice, the stable version of the formula is more often seen as a constant presence that remains powered on until the pathstones run out of vesanmer.
The formula for Venetian Walls was first written in 1718 by Society Alzamaster Maddalena Morosini. As a native of Venice, Morosini had grown up getting her ankles wet whenever the tide came in to flood the Venetian streets. One of her first projects upon being accepted into the society was to come up with a solution to this problem and allow Venice to control its floods. Her formula has since been modified to use as bridges, temporary shelters, and military fortifications. Although it is a difficult formula to memorize and even more challenging to use dynamically, an alzamaster who knows who to create a Venetian Wall will always find work.
