Auto Totem Swaper
by omgreal5406
Auto Totem Swaper keeps a Totem of Undying in the offhand slot by moving one from the inventory whenever the offhand is empty.
What it does
Players who fight, explore or build in dangerous places can lose a totem in one hit, and swapping it by hand while under attack is slow. Auto Totem Swaper searches the inventory and hotbar for a totem and moves it into the offhand as soon as the slot is free, so a replacement is in place without opening the inventory. The mod toggles on and off with the R key, and an in-game status message shows whether it is active.
The mod needs Fabric API and runs on the Fabric loader only. It is published in 12 release versions, with 1.0.0 for 1.21.11 as the latest file. Both the server and every player need it, because the swap logic runs on the client and server together. The code is released under the MIT License and is not open source. The author credits a friend, Arnav, for the idea, and notes that more updates are planned.
Key features
Automatic totem swap
When the offhand no longer holds a totem, a totem from the inventory is moved into the offhand slot at once.
Toggle with the R key
Pressing R turns the swap on or off, and the status appears on screen so the player knows which state is active.
Searches the full inventory
The mod looks through the hotbar and the main inventory to find a totem, so one stored in any slot can be used.
Fast and reliable swapping
The swap runs immediately and retries when a move is missed, so the offhand does not stay empty.

Who it’s for: Players on Fabric who want an offhand totem refilled automatically, and server owners who run Fabric and want the same behavior on their server.
