The Guardian Stone is most commonly known for it’s dropping in Upgoro Crater, but not known what it’s used for. I remember picking these bad boys up all the time about 10 years ago. Posted them on the auction house just because and they sold.
Now that my gold making experience has gotten better over the last few years. I know what the Guardian stones are used for. There are 7 different crafting recipes that require a good some of the stones.
