Multiple enchantments lvl 32767?

How can i do multiple enchantments with lvl 32767 on a single item in minecraft? I know how an enchantment works on an item, but not several.

You can only get such a high level with mods. In the original gameplay you can't have such high enchantment, there's at most Protection V and nothing over it.

You can get multiple enchantments with the anvil by combining the same items with different or the same enchantments.

Do you mean with a single command or what?

You would have to give yourself a new item which is assigned these values when it is created.

As far as I know, this is a plugin or possibly a mod. You can only do that with a command.
If you have enchanted the item with a command, try again. If it doesn't work, take a second item and try to craft them together in the anvil.

Otherwise read the hints, tips and help pages of your plugin / mod or go to support if it is offered.

I know and I need the command for this new item, please

Since you already know the command:

NBT uses JSON. There are 2 data structures in JSON. Lists and objects.

list
["a", "b", "c"]
object
{"a": 1, "b": 2}

Both can be combined with one another as required. You will notice that the NBT has square brackets around the innermost curly brackets. So just put a comma after it and insert a new object.

[{Enchantment 1}, {Enchantment 2}]

/ give @p minecraft: diamond_chestplate {Enchantments: [{id: "minecraft: protection", lvl: 32767}, {id: "minecraft: thorns", lvl: 32767}, {id: "minecraft: unbreaking", lvl: 32767}]} 1

I have now entered that, but have only received a slide breastplate with protection 32767, and no other enchants, why is that?

/ give @p diamond_sword {Enchantments: [{id: sweeping, lvl: 2}, {id: unbreaking, lvl: 3}]} 1

Here just insert the lvl

Thanks

It's normal in vanilla without mods…

Because there are spaces behind thorns and unbreaking.
