About this Mod
⚔️ Auto Breach Swap (1.21+)
Maximize your Mace attributes with zero effort.
Auto Breach Swap is a lightweight, client-side utility mod designed for Minecraft 1.21 and above. It solves the "Mace vs. Sword" dilemma by automatically swapping to your Mace the moment you initiate an attack with a Sword, ensuring you get the full benefits of Breach and Density attributes without having to manually scroll.
✨ Features
One-Way Attribute Swap: Hold your Sword for mobility/reach, and the mod instantly switches to your Mace slot when you left-click.
Persistent Slot Lock: Unlike other mods that force you back to the sword immediately, this mod stays on the Mace slot after the swap, giving you full control over when to switch back.
Fully Configurable: Use the in-game menu to define exactly which hotbar slot contains your Mace.
Toggle Keybind: Quickly enable or disable the mod on the fly with a single keypress (Default: O).
Version Proof: Built using modern Tag-based detection, making it compatible with all Minecraft 1.21 sub-versions (1.21.1 through 1.21.8+).
