well, the main thing is that it is only found on floors divivislbe by 10 to start off, and its easier to find on floors less than 250 like 100, but it seems that others can find it on floors that end with 5 if ur past 250. and other than that its EXTREMLY RARE, more so than alexandrite and pink diamonds.

I found it all the time. I just save outside the excavation site, go inside, find the hole, and if it's close to a floor ending in 0, then I just take the stairs down. It only took me about 5 minutes to get it.

You need to have all cursed/blessed tools before the mythic stone show up in the mine. Those tools usually don't show up in the mine until you have mystrile tools. The more mystrile tools you have, the better chances you have of finding more cursed tools that can then be blessed.
