Smart Mace Swap is a lightweight Fabric mod that automatically switches between maces with Breach and Density depending on your current movement state.
Whether you are on the ground, jumping, or falling from a height, the mod automatically selects the most suitable mace for the situation.
Automatically switches from your spear to the appropriate mace.
On the ground / while jumping:
Switches to a mace with Breach.
If no Breach mace is available, no switch occurs.
While falling:
Prioritizes a mace with Density.
If Density is unavailable, switches to Breach.
If neither Density nor Breach is available, no switch occurs.
Smart automatic mace selection based on your movement state.
On the ground / while jumping:

While falling:
Density — highest priority.
Breach — used if Density is unavailable.
If neither mace is available, no switch occurs.
