Altering Weapons

As of 1.2, you can now place already crafted weapons in the bars slot of the Forging Interface, provided they were not crafted through this mod. This means you can take an existing item, such as the Fiery Greatsword, and modify it by adding an effect, an affinity, a jewel and a Broken Hero Sword.

However, this feature is not limited to items in unmodded Terraria; you can also take an item from another mod, and alter it through this process.
