i got the fire and water crystal just mastering different moves and earning gold for bottled lighting all you gotta do is take hits and chuck lighting at the gaurdian
im going to love it when i upgrade my blacksmith efficiency to 100%.
I would never need to use gems again!
think about it if most fail i could keep trying forever.
also gems would only used be used on the upgrades.
then you could fly through the hell stone lvl's.
it might take awhile to upgrade your pick.
but you'll get alot of $$$$ for upgrading.
+ this to know the possibilities of pick power. also happy new year!
