Devs are trash. They change the game whimsically. I had most of my soul stones max out at 300 then they updated it to max out at 1500 and then they reverted it back to 1500. After the revert my soul stone lvl went down. Some are less than 100. Wasted about 2 days of farming. Better find another game where you won't waste your time farming for nothing. If I could give a rating less than 1 I would.
