TrinityCore: Item Creator
This application allows the user to generate queries for the item_template table in the Database. You are able to modify every single row to your specific need, and it includes some fail safe mechanisms. The application is easy to navigate and shouldn't be too hard to figure out.
Note: I only spent around 5 hours on this application. The only reason that I'm releasing this application is because I only made it to improve my scripting and therefore have no use of it. Feel free to report any errors you may encounter, and I'll fix them once I get the time.
