According to your calculations, who wants to get this achievement needs to have many basic resources 7+5+3+3+3=21 thousand. And crystals, 2.5 for each potion, for a total of 25000. A total of 46 thousand resources. If they are quick and easy to sell at 1 coin, the proceeds will be 46000. If partially sell for 2 coins, you can get 50-60 thousand. And that's not counting
"a large supply of sand, glass, copper, steel and other ingredients ...artifacts"
as well as the prices of recipes for the production of all this stuff.
So BRAVO!
" the result is worth it"
