Once you've ordered the appropriate license for yourself, you can get a forge (as well as the crafting table) from Bado after you have activated the 2 central switches to get to the boss room in the Water Ruins, which you can place wherever you choose. Please note that the option for the license will not appear until after you've talked to Bado and he has stated that it's time for you get a forge. Forging is used to make weapons and farming tools, and you can get the recipe bread for either of these by eating the appropriate recipe bread sold by Porcoline. The item's skill level must be within ten levels of your own or less. You can also make items without a recipe, if you so choose, but it will require a lot more RP than it usually would if you learned it from recipe bread.
A magic bread that teaches you new recipes. You can learn one (simple) recipe appropriate to your skill.
When you use the forge, you will be given the option to make a weapon, tool, or upgrade. If you chose weapons, you will get another option menu for the type of weapon you wish to make before going to the forging menu.
This game is the first to use a classification of monster items; for example, cheap cloth and insect carapace both are a part of the cloth and skins class. Many tools and weapons require a certain class of item in place of requiring specific drops. You could use a cheap cloth in place of an insect carapace when making a waterpot, so to say.
While forging, the player may add additional items if there are still any empty slots left to fill out. Adding items may give the forged weapon more benefits aside from the base stats it provides, and this is highlighted with the weapon's name being blue when selected. These effects can either stat-related, where the weapon will offer more benefits than it normally would, status-related, where negative status effects can be added in by items like Poison Powders and Paralysis poison, attack-related, where Crystals can be added to change a weapon's base element or for them to have additional effects like lifesteal, or aesthetic-related, where items like Shade Stone and Invistone affect the weapon's range and appearance respectively.
Another feature is the introduction of the Light Ore; Allowing the player to transfer the stats of one weapon when they forge another. For example, if the player attempts to build a Broadsword, but includes a Spoon and a Light Ore, there will be a chance for the Spoon's base stats to replace the Broadsword's upon creation.
It is possible to "upgrade" platinum tools by adding a Light Ore and a Sacred Pole to the recipe. Doing so will give the platinum tool in question a fourth and final charge that increases the area of effect from nine plots (3x3) to sixteen (4x4) and costs no RP to use. This only applies to the fourth charge: using the first three charges will cost RP.
The only exception is the Blessed Hoe. The area of effect will not go beyond four plots (2x2), but no RP will be consumed when the hoe is swung.
This trick can be detrimental in some instances, however. Crafting a Platinum Hammer in this manner appears to greatly reduce its effectiveness as a hammer, as ores mined with this hammer appear to break quickly and generate very few minerals and jewels, regardless of the player's mining skill.
