This item cannot be bought, only found, but can be sold for 1050. In the Johto region games, this item can be found in Mt. Mortar and at the PokÃ©athlon Dome in PokÃ©mon HeartGold and SoulSilver.
A millstone weighing a ton or two can do a lot of damage before it comes to rest. A millstone turning 125 revolutions per minute will destroy the millstone cover and I seen then destroy machinery in a mill and go through a 14 inch square log wall like butter and before they come to rest out side the mill.
Therefore, if a Hard Maple at 20 dbh has a merchantable log length of 30 ft. it will have approx. 250ft. including defects etc. or 1 full cord. The crown would weigh about half that much if it was a forest tree. Therefore the average 20 maple would weight 4 tons. One bf of MH weights 13.5 # in roundwood form. Since pine is half the weight, but taller and smaller of crown, I would think a 20. White Pine would weigh 3 tons depending on time of year and MC.
