Quest 1: Make 150 Baskets, Donate 5000 Saltpeter, Earn 400 Exotic Wood Planks
Making the baskets is around a full day, but is a 'push' - you can sell or use the baskets and the 'production cost' is worked into the price.
5000 saltpeter = 2500 gold. (or so).
400 exotic wood planks, 100 gold or so.
So this quest is:
"Tie up your provision house for a full day (Half a day if you rabbit for another 300 gold!), and pay a net of 2400 gold!" (More if you have to buy the saltpeter after-the-fact because the price will be going -up- temporarily.)
Quest 2: Find 30 Granite, Trade 20,000, Earn 150 coin.
"Find" is a (time consuming) push. "Trade" is a (time consuming) push.
So this quest is:
"Time passes, earn 150 gold."
Quest 3: Produce 500 Sausage, Buff 200 Friends Buildings, Earn 150 Map Fragments.
"Produce" is time consuming, and -requires- specific buildings.
"Buff" is time consuming (at 200!), and costs 4+ per basket. So 800.
Earn 150 mp = 750 gold.
So this quest is:
"Build specific buildings, time passes, and pay 50gp."
