Finish a 30-minute Era with a Village with at least 400 prosperity and no two of the same Natural Sources within borders
Spread your Giants out and make three or four villages. We need to earn ambassadors fast in order to access the most diverse number of resources. With that in mind focus ambassador selection on power and aspect diversity - we need lots of different things.
Then it's a case of returning to one of your earliest villages and reading symbiosis very carefully. Blueberry next to strawberry, check. Chicken feeding from blueberry, roger. Pear Tree surrounded by Blueberry and Apple Tree, yup, and the Apple Tree is next to a animal. Right.
Pause Often . It's never been so necessary to pause before. With a tight time limit you need to pause and ensure that your Giants are acting simultaneously, placing materials alongside each other, and that they are always active. Don't leave the Ocean Giant standing idle, have him dropping fish in the sea or giving another Giant a Speed buff! Do a lot of things in the shortest space of game time possible, and to do that you need to pause.
Remember to apply potent aspects whenever possible and if you're struggling, we recommend working on a second or third village simultaneously purely for the ambassador prospects. Also note the words 'within borders' This means you can have two rabbits outside the border at no penalty to your Development.
In all honesty you're more hoping for a good Great Project to appear. A 'so many animals within borders', or some such, as these will seriously boost your village's prosperity. This is why you need to return to your first village for this task - it's most advanced and likely to begin a great project within the thirty minutes.
