Not sure how Demon Piece weapon upgrades work yet? Firstly, you need to find the right NPC, and then you need to gather some materials!
Do you have a weapon you need to upgrade? Head over to the Demon Piece page then! Check out our Demon Piece Scroll Locations guide, our Demon Piece Haki guide, and our Demon Piece Thunder God guide to learn more about the game.
Demon Piece Weapon Upgrades
To upgrade any weapon, you must visit the Blacksmith NPC. He stands in Logue Town by an anvil within a warehouse – there a wooden crates behind him too! You can interact with him to upgrade a weapon of your choice, but you have to collect certain materials of a specified quantity before he can do so. Not only do you need the upgrade materials, but you also need to save up your Beli! The rarer the weapon, the more Beli an upgrade costs.
Upgrade Materials
Some materials upgrade your current weapons, and some forge new ones! In this guide, I’m focusing on the materials that are purely used to upgrade your already-existing weapons. On top of that, each material has a rarity, which mostly coincides with the rarity of the weapon that requires it for upgrade. All materials are either found in chests or dropped by enemies (mobs and bosses!).
