Combining items whose combined durability is more than 100% actually wastes more resources than simply using tools until they break. The precise combined durability for efficient repairs is shown in the following table.Ī perfect repair is theoretically possible, but unlikely in practice. In the example, repairing a stone tool restores a bonus of 6 durability, which is actually only 6/132 = 4.5%. The order in which items are combined does not matter one sequence of repairs gives exactly the same durability as any other. The greatest benefit is gained when the two items have a combined durability of at most approximately 95%, in any combination, such as 47.5% + 47.5%, 94% + 1%, 10% + 10% or any other values that total 95% or less. Or, in terms of percentage (approximated): A newly crafted stone axe would have 61 uses. Where "floor" means round down to the smaller integer, and "min(x,y)" means the smallest of x or y.Įxample: Two stone axes have 10 and 45 uses.

Min( Item A uses + Item B uses + floor( Max uses / 20), Max uses) The formula for determining how many uses a repaired item can have restored to it in the crafting box, is as follows: Tools made of different materials (for example, a wood and a stone pickaxe) cannot be combined. Therefore, using a "junk" item in a repair may sometimes be useful for removing an unwanted enchantment from an item prior to enchanting it again. The repaired object is never enchanted even if both items were to have the exact same enchantments, with the exception of curse enchantments, which are transferred to the repaired item. Repairing gives a slight benefit in conserving inventory space, as it combines two non-stackable objects into one.

The durability of the repaired item equals the sum of the old items' durability plus a 'repair bonus' of 5% of the item's maximum uses, up to a limit of the maximum durability for that item. Two items of the same type and material can be placed anywhere on the crafting grid or grindstone, which results in a single repaired item.
