３鍛冶ツール for DQX is a free Android app developed by blazeworks for craftsmen of the weapon, armor, and tool forging professions in Dragon Quest 10. The app offers a range of helpful features such as a temperature chart, damage calculator, success zone record, and damage prediction.

One of the most significant features of the app is the ability to record success zone values. While the app comes with a set of predefined data, users can contact the developer through the in-app bulletin board to add more data. However, the developer cannot be held responsible for any data loss due to uninstallation or other reasons. Additionally, any errors or mistakes in the predefined data are not the responsibility of the developer, but they can be corrected upon request through the in-app bulletin board.
