well,the pieces you can get frommay be wrong but I worked out
I want a minimum 8 pieces = minimum 9 crossings + apprentice league + 2 from quests
For 8 pieces probably need to buy 20 ingredients = min 2450 Diamonds
and that was without a barn upgrade in the middle of the table crossings (I am not bothered about having the barn fully upgraded, I want 8 bits of fields)
2 milestone
2 silver league
4 gran prize(1,3,7,9)
