These are 3 Enchantments, that are purely used, to make the Raj Raksha Boss work.
They are:
Nothing that is intended for Player.
If you have one, the best thing to do, is destroying, and reporting it to the structure creator.
I intend to punish players, in a future version, who use them.
None of them are intended to be obtainable by Player, or used by Player.
They can only be obtained from other faulty datapacks.
Explanation:
In the Update to Minecraft 1.21, Mojang changed how the “enchant_randomly” function in Loottables works.
In 1.21, This function now needs a source called “option”, where you would specify the pool of enchantments that can be used for the function. For example: “#minecraft:treasure” for treasure enchantments or “#minecraft:in_enchanting_table” for enchantment table, enchantments.
If you miss this option, Minecraft will not show an error but will instead call enchantments from everywhere it can find them. Even those that can't be obtained.
