After unlocking and buying a forge, it is fairly easy to quickly level up the forging skill. Making anything with the forge will give experience, with higher difficulty items giving more experience. The only factor that determines the experienced gained for each item forged is the required level of the item- thus making items that require fewer and less rare materials is the best way to level. One of the easiest ways to take advantage of this is to mass-produce hoes, which are made from only one item, an ore. Make sure that you have obtained the recipe for the Cheap Hoe, and check to see that you have a decent supply of Iron. Mass-produce Cheap Hoes by using the arrow at the lower right corner of the touch screen, watching the required RP to insure that you will not faint. Make as many as you can hold. At lower levels, it is also a good idea to upgrade the hoes up to level ten using whatever useless items you have picked up to gain more experience. The experience needed to level the forging skill increases with each level, so after a while, forging Cheap Hoes will become less effective for raising your forging skill. At this point, start making the next level of hoe, and continue to mass-produce the appropriate leveled hoes with your extra materials to quickly level your forging skill.
