Finish an Era with a Village with 1000 Wealth in Use
As with the Modern Banking development our focus is upon Minerals and Animals placed in a Desert biome. To this end it’s recommended that you equip the Rock Giant with 3 Desert Ambassadors and 1 from any biome, and to get the Swamp Giant set up with 2 Desert, 1 Swamp, and 1 ambassador from any group.
The only think that changes with this challenge is the density with which you need to place the resources. Onyx, Gold, Onyx is a sure way to generate a huge and instant boost of wealth (roughly 250-300 depending on Aspects/Resource level)
From here your focus is on creating and boosting Onyx and Swamp Giant animals, encouraging the village’s expansion over time. Over the two hours it’s not impossible to see a village expand to encompass more than 14/15 resource tiles, while projects can easily help out with this target. Remember to save often and reset upon project creation; you might find a more convenient symbiosis!
