About this project
What does Hephaestus Fabric add?
Hephaestus is a Fabric port of the Forge mod Tinkers' Construct. Hephaestus is a mod about putting tools together in a wide variety of ways, then modifying them until they turn into something else. The tools never disappear and can be named and changed to your heart's desire. Once you make them, they're yours forever. Many different materials can be used to make your tools. This mod doesn't add anything besides making it compatible with Fabric. For more info about the mod itself see the Tinkers' Construct page.
1.18.2 builds have been archived due to them having critical bugs.
No support will be given if you are using a 1.18.2 build
