You'll need to build the Relic, just as you have all of the others, using materials collected from friends. In this case, the first stage of the build requires 1 each of Metal, Ectoplasm, Gold, Pillars, and Paint. You can accept these items either as general gifts from your friends (that they initiate), or you can click on the "Ask for More" button associated with the item you want to post a request to your wall asking your friends for help. Remember, you can have five of these requests active on your account at one time, so feel free to ask for all five if you don't think your friends would mind.
All told, there are four steps to the Ziggurat's construction, requiring a total of 10 of all of the individual ingredients, or 50 items. Once completed, you'll earn a permanent +3 maximum energy boost, that will stay active on your account until you store or sell the relic, at which point the boost would be removed.
