Batch Repairing

Batch Repairing

This tiny mod allows you to combine more than two items with durability on the crafting grid to repair equipment.

In vanilla Minecraft, two items can be placed on the crafting grid or the grindstone to get a single repaired item. However, there are more than two available slots when you are crafting (in the inventory menu or crafting table menu). Batch Repairing allows any number of items placed together on the crafting grid to be combined for repairing. This helps simplify the process of combining damaged items in bulk.

With Batch Repairing

Durability Calculation

Any number of items that have durability can be placed in any slots on the crafting grid. As long as the items are the same type and consist of the same material, the result will be a single repaired item.

The durability of the repaired item is the sum of the old items' durabilities plus a bonus of 5% of its maximum uses for every extra item added after the first one. For example, combining three stone axes with 10, 20, and 30 uses left respectively results in a stone axe with a durability of 73:

10 + 20 + 30 + 5% × 131 × (3 - 1) = 60 + 13 = 73

Where 131 is the stone axe's maximum durability and 3 is the number of stone axes combined together.

This formula matches the one used by Minecraft to calculate the durability of the result of two combined items and ensures you get the same outcome as if you combined the same items together two at a time.

Enchantments and Curses

Enchantments on items do not transfer to the repaired item except for curses. Combining items with different curses results in an item with all the maximum level of enchantments from that set of curses.

When placing a single item with non-cursed enchantments on the crafting grid, the result is the same item but without the enchantment. This mechanic lets you easily disenchant items from your inventory (or a crafting table) without having to use a grindstone. The tradeoff for the convenience is that you don't get experience points from doing so.
