Certain weapons can be upgraded into powerful forms imbued with special attributes by using money and materials. Most weapons that serve as a base for these transformations can be purchased at stores.
Any weapon without a special damage type or attribute has the potential to become stronger through crafting. If you've obtained one, trytaking it over to Julie's Gearworks.
Materials come in various forms, such as lava stones, electric stones, rainbow stones, ice stones and more.
You can spend metals and money to upgrade any weapons to a max of+50, ultimately reaching 7 stars.
Upgrade values carry over when a weapon is used to craft a new one, so don't be afraid to upgrade the weapons you currently have on hand.
Additionally, by upgrading to certain levels, you'll unlock a brand slot, allowing you to customize weapons with special abilities.
