Description

When repairing an item with multiple repairs at a time (IE, using 4 diamondsto fully repair a nearly broken diamond chestplate), all 4 diamonds are consumed, but the chestplate only repairs enough durability as if only one diamond were used.
Additionally, if the chestplate is only damaged enough that 1 item is enough to repair it, then only one of the multiple diamonds is used.
