Stage 3. At this point it starts to get expensive so you will need to earn some money (see money making guide) After having built many forges they too must be converted. These are to be converted into subterranean factories. At each conversion upgrade to level 3 before continuing to the next building this will save your plunder. By the time you reach the highlands the big boys take over this again is a mass conversion. Before you do go to the final stage upgrade your guilds to level 4 this again is good for your plunder. In the highlands the attack building can be seen as the attack stats will be higher than defence, using the same technique gradually convert your buildings into t4 at the end of your building change your guilds into strongholds of shadow this may damage your plunder whilst being built but fully upgraded this will be very useful. Next guide money making.
