The Terrace Farm in Forge of Empires is a Special Building (Production) that can be obtained as a reward through the Guild Expedition. There are two ways to get it: through the Rare Jade Relic or completing level III and IV.
If you opt for the Terrace farm, you’ll have six production type options from which to choose. Now depending on when you earn the Terrace Farm, or the age of your town, will reflect the amount of resources it produces.
You’ll soon notice that it is not possible to motivate your Terrace Farm which means that it is subject to plundering at any moment once production is finished.
The Terrace Farm can produce coins and supplies by this will depend on the happiness of your town and if you have any other Special Buildings that are giving it a boost.
