In Minecraft, the NBT (Named Binary Tag) format is used to store data of our Minecraft worlds, including block, entity, and item properties.
In the Java Edition of Minecraft, you can modify this data by including the data in the command, like so:
/give @s diamond_sword{Enchantments:[{id:"minecraft:knockback",lvl:10s}]}
In the Bedrock Edition, on the other hand, NBT is inaccessible from commands. In order to modify NBT, we need to use an external editor.
What are some useful item properties that I can modify with an NBT editor, and how can I do so?
