I know you are suppose to get Engenering 2 first, and have a Master Builder. But how do you get a master builder? My builder is staying Adept for the longest time! Anyways, my real question is this: What do I do to build the dam?? Do I need more then one master builder? Please help! Thanks! :)!

(Sorry if this is the wrong place to post this on.)

You can find the details in the Guides Section - look for the detailed solutions thread.

you can have someone untrained in building to help build the dam or even start it
