refueling my flying sword

Phsyco - Lost City

Hi, I was wondering what the best stones was for refueling my flying sword. I tried decomposing armour and using the yuyan stones but they only fuel it by 1 point so it would take 300 to completely fuel it. I also tried a mirage celestone but it only fuels about 20 points and I really don't wanna spend that much. Is there any other cheap way to go about it?

2-star items tend to decompose into a lot of stones; I've gotten more than a hundred off one pair of boots that way. There are higher grades of stones, which higher level items will decompose into, and those are worth more points for your aerocraft (and the higher level items tend to give more stones).
