Automatic replacement
by xupengrui
Automatic replacement is a Fabric and Forge utility that refills the offhand with a Totem of Undying as soon as the slot empties.
What it does
When the offhand slot runs empty, the mod moves a Totem of Undying into it from the inventory. A toggle in the ESC Options menu turns this behavior on or off, and the mod adds a Mixin Options button there for the same purpose. Min Y and Max Y settings control the world height range, which the mod extends from -128 up to 1024.
Other changes cover item stack sizes: the Totem of Undying stack size is raised to 8, and many other item stack limits are adjusted. A global setting syncs the choice across players on a server, and the networking runs through Fabric API. Client and server both need the mod, so the server and every player install it.
Required dependency: Fabric API. The mod is released under the MIT License and is open source, with the source code and issue tracker publicly linked. Files target 1.20 – 26.1.2 on Fabric and Forge.
