This is just to help everyone understand the coin cost to produce balloons.
Your goal is 15,000 balloons for the ultimate personal reward of a field medic general.
You can make ~840 balloons daily without your festival hall buffed. (maximum is about ~980)
1,260 with petite cake buffs. 1680 with enormous cake buffs.
You have 14 days to this.
Now if your someone not rich in resources, the following table may help you adjust your resource conversion that best supports your economy.

This table applies mainly to the players in Ares as these are price ranges of those resources on Ares' server.
I hope it helps those in Zeus also as this is a COMMUNITY event and we need every able man, woman, child, & pet to reach the 500,000,000 goal in 7 days. If those prices are similar on your server, great.
If someone in Zeus would like to share the resource costs of the resources in the table, I can calculate the balloons per coin for each resource for you guys as well.
