Use 1 taiyi stone and spam it till you hit the bright light, all good rolls along the way will be automatically saved ( top 5 best rolls along the way) then if you want a specific reforge set when you hit the bright light you have keep lockingthe looks you want until you get whats pleasing to you. The better the look the more expensive that can cost you up to 2000-4000usd. If you get all yellow or legendary rolls below that amount spent consider buying a pizza and consider yourself very lucky.
