Java Edition data values/Pre-flattening/Item IDs

All items have values above 255, making it easy to separate the Block IDs from the Item IDs. Entries marked with a D use the item's Damage field to define its durability, while those marked with a B require data from the Damage field to fully define the item in a world. The chainmail set is currently obtainable in Survival mode via Villager trading, rare mob drop (armored zombie or skeleton), hacking, or the /give server command. It is available in Creative mode normally.
