You specify a point on a surface that you can see within casting distance and cause that point to appear as a channel continuously until the spell terminates. The selected surface must be wood, gray, or stone (such as a wall, roof, or floor). The size of the opening is up to you: it must be at most 5 feet wide, 8 feet high, and 20 feet deep. In addition, the channel does not destabilize its surrounding structure.
