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, however there are plans later to add some exclusive content and possibly tweak some of the current content. For more info about the mod itself see the Tinkers' Construct page.
1.18.2 builds have critical bugs that may ruin game-play experience. They are effectively archived.
No support will be given if you are using a 1.18.2 build
A 1.19.2 PORT IS NOT HAPPENING!
I don't have the time and motivation to do 1.19.2.
So stop harassing me to support older versions.
