In Monster Hunter Freedom, Hard Monster Bone can be obtained by breaking certain monster parts. To increase your chances of obtaining Hard Monster Bone, focus on targeting specific parts of monsters that are known to drop this material, such as the head or back. Additionally, using weapons with high impact damage, such as hammers or hunting horns, can help break these parts more effectively. Good luck in your hunts!
