TOTEM LOCK
by Knightiix
Totem Lock keeps a Totem of Undying in the off-hand slot so a stray key press cannot pull it out mid-fight.
What it does
The mod blocks the F key, which normally swaps the main-hand and off-hand items, while combat is underway. The Totem of Undying stays in the off-hand slot, so a player fighting another player or a mob cannot move it out by accident. The swap-hands key still works inside the inventory screen, and the Q drop key and the hotbar keys 1 to 9 keep their default behavior when the off-hand slot is not involved.
The Totem Lock author built the mod for PvP and crystal or anchor fights, where one unintended keypress could remove the totem at the wrong moment. Totem death protection itself is unchanged, so a totem still saves the player when it is in the off-hand. Only manual removal through the keyboard is blocked, and deliberate inventory management still works as before. The mod is a client-side Fabric mod with no server component.
Installation requires Fabric API. Builds target Minecraft 1.21.11 and 26.2, and the mod uses only vanilla classes through Mixin. Fabric Loader 0.19 or newer and Java 21 are needed to run it.
Key features
Locked off-hand totem
The Totem of Undying in the off-hand slot is kept there during combat, so it cannot be swapped out with F.
Keyboard removal blocked
Only the keyboard path for taking the totem out of the off-hand is cancelled, and the mouse stays free for inventory work.
Inventory management kept
Moving items through the inventory screen and dropping items with Q work as they do in vanilla.
Death protection unchanged
A totem in the off-hand still triggers its normal effect when the player would otherwise die.

Players in close combat can keep the totem ready without spending attention on the swap key.

Who it’s for: Players who fight other players or mobs often, and who want the off-hand totem to stay put during combat.
