Manor Improvements (Defenses) - cragstone/Pendragon GitHub Wiki

When creating a Motte as an item it is important to use the PID 'i.manorImp.motte'. When calculating the Defensive Value (DV), the system will, if it finds a defensive improvement with this PID in the motte location, add the DV of the relevant stronghold to the motte DV. If you add a double or triple Motte instead (with a different PID) will not get the bonus.
