Swap Helper

When a player attacks with a Sword or an Axe, the mod can switch to a Mace from the hotbar for the follow-up, then return to the previous weapon. It covers Sword Mace and Axe Mace sequences, and its breach swap is meant to make mace combat feel smoother and faster. Only the nine hotbar slots are checked, so a Mace kept in the inventory is ignored. When several Maces sit in the hotbar, the leftmost one is selected.

Timing is handled through configurable swap delays, and a toggle key is bound to P by default. Shield stun slams are supported, and an axe used against a player blocking with a shield is detected as the attack that starts the sequence. A configuration screen lets the player adjust the options, and any feature can be disabled there. The mod is built to stay lightweight, with no extra HUD elements.

The mod is client-side only, so only the player's game needs it and servers run without it. It is published for Fabric alone, which requires Fabric API, for game versions 1.21 – 26.1.2 across 15 release versions, and the latest file is 1.1.0 for 26.1.2. The code is under All rights reserved and is not open source. Players should check a server's rules before using automated combat features, since some servers restrict combat-assistance mods.
