VE Att Swaper

Efficiency Swap

Efficiency Swap is a client-side Fabric mod for Minecraft Java Edition 26.1.2 that automates Efficiency attribute swapping between two pickaxes.

Features

• Press **Shift + H** to enable or disable the mod.
• Detects the iron pickaxe with the highest Efficiency level in your hotbar.
• Uses that Efficiency attribute while mining with a selected netherite pickaxe.
• Keeps the netherite pickaxe responsible for block drops and durability loss.
• Protects your netherite pickaxe when it falls below 30 remaining durability.
• Automatically switches to the healthiest safe netherite pickaxe in your hotbar.
• Replacement pickaxes must have **Silk Touch** and at least 30 durability.
• Blocks mining if no suitable replacement pickaxe is available.
• Displays action-bar messages when toggled, automatically switching tools, or protecting a low-durability pickaxe.
• Compatible with Fabric and Lunar Client on Minecraft 26.1.2.
• The server does not need to install the mod.

How it affects gameplay

Players can mine using their normal Silk Touch netherite pickaxe while borrowing the Efficiency level from an enchanted iron pickaxe in their hotbar. This allows the netherite pickaxe to retain its normal harvesting properties while benefiting from the source pickaxe’s mining-speed attribute.

For example, a player can keep an Efficiency X iron pickaxe and a Silk Touch netherite pickaxe in their hotbar. With Efficiency Swap enabled, the player selects the netherite pickaxe and mines normally. The mod automatically handles the required hotbar packet sequence.

When the selected netherite pickaxe falls below 30 durability, the mod searches the hotbar for another safe netherite pickaxe with Silk Touch. If one is found, the mod switches to it automatically. If no replacement is available, mining is blocked to prevent the original pickaxe from breaking.

Important server notice

This mod relies on Minecraft 26.1.2’s attribute-swapping behavior. It may not function on servers that patch or disable attribute swapping. Some servers may prohibit automated swapping or rapid slot packets, so players should check the server’s rules before using it.
