This skill permits a noble to add a moat to an existing castle. A moat prevents attacking missile troops to approach the walls of the castle close enough to be effective against troops inside the castle. A castle with a moat adds 100 to the defense rating against missile weapons of all the troops it protects. This bonus does not apply to missile siege weapons attacking the castle, since they are stronger and not bothered by the added distance. To use this skill, a noble should be inside the castle to be improved and have at least 1 worker.
Building a moat requires 200 [78] stone, and 4000 worker-days of effort.
A damaged castle cannot be improved until it has been fully repaired.
