Java Edition:Negative Durability Sword
In RC1, all swords are coded to have only 5 durability. This change allows negative durability swords to be obtained.
Obtaining
Any sword that has been damaged more than 6 times will become negative if updated (or downgraded) into RC1. The durability will always be 5 - Amount of Damage. In order for the sword to remain negative beyond RC1, multiple swords must be combined in a crafting grid for an even more negative durability. The total damage must become greater than the sword's durability in later versions. Since the swords' durabilities are only 5 in this version, the 20% bonus only adds 1 durability when combining. Therefore, the crafted sword's durability is the sum of the two negatives plus one in RC1. A list of the durabilities that must be exceeded are below.
In RC1, the most damage possible is 32767. Attempting lower can result in a integer overflow, creating a negative damage value or an extra durability sword. Extra durability swords convert to regular zero damage swords in 13w09b (1.5 snapshot). In 17w47a (1.13 snapshot) and later, the damage can be combined all the way up to 2147483647.
Durabilities
The durability amounts (in the table) must be exceeded to keep negative durability past RC1. If the damage count is equal, it will only result in zero durability swords. The damage can be checked with a program such as NBTExplorer. It is possible to obtain a netherite negative durability sword if a diamond sword is upgraded to 20w10a (1.16 snapshot) and later.
